Title: Influence of different pulsing and holding solutions on vase life of tuberose
Abstract: Extended of the vase life is a crucial point of view for commercial cut flower. To improve the vase life of tuberose some preservative solution viz. T0: Tap water (Control); T1: Sugar (50-ppm); T2: Citric Acid (50-ppm); T3: Salicylic Acid (50-ppm); T4: Chitosan (50-ppm); T5: Silvar Thiosulphate (50-ppm); T6: Sugar + Citric Acid (50-ppm); T7: Sugar + Salicylic Acid (50-ppm); T8: Sugar + Chitosan (50-ppm) and T9: Sugar + Silvar Thiosulphate (50-ppm) were used as vase solution. Maximum floret opening (42.7%), first floret wilting (4.3 days), first petal dropping (5.3 days), solution uptake (74.0 ml), petal water content (54.3%) and vase life (9.7 days) was found from T7 which was followed by T6. Findings of the study indicated that carbohydrate and acidic mixture as vase solution greatly influence the shelf life of the cut tuberose.

Title: Flowering, fruiting and seed maturity of common plantation tree species in Bangladesh
Abstract: Flowering, fruiting and seed maturity are important aspects in the life span of a plant or plant community. These phenological characteristics have great significance in plantation program. A study was carried out from January, 2011 to March, 2012 with a view to explore these phenological affairs of 65 commercially important plantation tree species. The research was conducted covering wide area of hill forest and plain land Sal forests of Bangladesh through repeated field visits and review of literature. The results showed that flowering, fruiting and seed maturity period varied from species to species The findings of the study represent that most of the studied species bear flowers (32 - 33 species) and fruits (26 - 29 species) during March-May and April-June respectively. The flowering period varied from 3 to 5 months among the species. The results also showed that viable recalcitrant seeds of most of the species can be collected between May and June with, while for very few species seeds can be collected between September and October. The findings will be helpful to the nursery owners, small scale planters and forest managers to know the information of fruit setting and time of seed collection for raising nursery with desired plant species.

Title: Effect of high temperature on some physiological parameters of grain growth and yield of boro rice varieties
Abstract: A pot experiment was conducted with four varieties viz. Binadhan-5, Binadhan-6, Binadhan-8 and Iratom-24 in the plant growth chamber at Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh to assess the effects of high temperature at different growth stages on yield and yield attributes and photosynthetic rate, transpiration rate, leaf conductance and water use efficiency during grain growth period. For yield and yield attributes the following five treatments T0 (Ambient temperature), T1 (36°C at tillering stage), T2 (36°C at panicle initiation stage), T3 (36°C at booting stage), and T4 (36°C at flowering stage) were applied. Two temperature treatments T0 (Ambient temperature) and T1 (30oC) were also maintained during grain growth period. Temperature treatments significantly decreased number of total tillers and effective tillers per plant, filled and unfilled grains per panicle, 1000-grain weight, grain yield per plant and harvest index but plant height, non-effective tiller number and panicle length were not affected by temperature treatments. High temperature stress (36oC) at panicle initiation reduced grain yield more compared to other treatments. The grain dry weight, photosynthetic rate, leaf conductance, transpiration rate decreased but water use efficiency of flag leaf increased with temperature treatments. Binadhan-6 showed the highest grain dry matter accumulation under temperature treatments during grain growth period. Binadhan-6 seems to be tolerant to high temperature.

Title: Screening for BLB resistance in BRRI and BINA released rice germplasms using RAPD marke
Abstract: The present work was conducted to identify Random Amplified Polymorphic DNA (RAPD) markers linked to the rice Bacterial Leaf Blight (BLB) resistance gene for a marker-assisted selection program. Eight genotypes were screened by RAPD marker. These are Iratom 24, Binasail, Binadhan 4, Binadhan 5, Binadhan 6, Binadhan 7, Brridhan 29 and BR 14. Out of 12 decamer random primers, two were used to amplify genomic DNA and the primers yielded a total of 12 RAPD markers of which 2 were considered as polymorphic. The primer 70AB10C10 produced maximum number of bands (7), whereas the least number of bands (4) was generated by the primer 71AB10G11. The percentage of polymorphic loci was 36.36. For all loci, the average number of allele was 1.1818 and the average number of gene diversity was 0.0787 and their standard deviation and mean were 0.4045 and 0.1758, respectively. A dendrogram based on genetic distance using UPGMA, indicates segregation of eight germplasms of rice into two main clusters Iratom 24, Binasail and BR 14 grouped in cluster I, while Binadhan 4, Binadhan 5, Binadhan 6, Binadhan 7, Brridhan 29 in cluster II. In cluster I, Iratom 24 alone formed sub cluster I; Binasail and BR 14 formed sub cluster II. In cluster II, Binadhan 4 forms subcluster I and Binadhan 5, Binadhan 6, Binadhan 7, Brridhan 29 grouped in sub cluster II. Brridhan 29 formed alone sub sub-cluster I. Again, sub sub-cluster I; Binadhan 7 formed alone cluster and Binadhan 5, Binadhan 6 formed sub sub-cluster III.The highest genetic distance (0.2007) was observed in Binasail Vs Binadhan 5, Binasail Vs Binadhan 6, Binasail Vs Binadhan 7, Binasail Vs Brridhan 29 and BR 14 Vs Binadhan 5,BR 14 Vs Binadhan 7, BR 14 Vs Brridhan 29 germplasms pair whereas, no genetic distance was estimated in Binadhan 6 Vs Binadhan 7, Binadhan 6 Vs Brridhan 29, Binadhan 5 Vs Binadhan 7, Binadhan 5 Vs Brridhan 29. Results are discussed considering the potential utility of the RAPD markers found, for marker assisted selection in rice breeding programs aiming at developing rice varieties with durable BLB resistance based on a combination of resistance genes.

Title: Correlation and path coefficient analysis of Blackgram (Vigna mungo L.)
Abstract: Blackgram (Vigna mungo L.) has the potential of supplying a major portion of protein demand and restoring the soil health at the same time. Research on genetic variability and correlation study between yield components of the genotypes of this crop may increase the opportunity to exploit its potential which will help meet the demand of high yield and nutrition supply. Current aim is to study the correlation coefficients and path coefficients between the genotypes to establish the selection criteria which might help to develop genotypes of high yielding potential. Moreover, studying the contribution of the yield components towards yield is also the purpose of this study. The experiment was conducted at Bangladesh Agricultural University in the summer season of 2012. Ten germplasms were evaluated through 11 morphological traits. Among the morphological traits pod weight (g) 8.81%, harvest index (7.72%), number of branches plant-1 (6.18%) and 100-seed weight (g) 5.24% had shown the highest level of coefficient of variation. Grain yield plant-1 had the highest heritability (99.43) and seed pod-1 had the lowest heritability (53.10). Relationship between physiological characters and yield contributing attributes was studied through analysis of correlation. In the present study, out of 55 associations, 22 associations were positively significant and the rest 16 were negatively significant. Yield plant-1 was positively and significantly associated with pods plant-1, pod length, weight pod-1, harvest index and 100-seed weight but negatively associated with plant height, fresh weight and dry weight. The result of the present experiment indicated that number of pod plant-1, pod length and 100-seed weight were the most important characters which exhibited positively to yield plant-1. It was observed that biomass plant-1 (0.73 g) had maximum positive direct effects on yield plant-1 followed by pods plant-1 (0.37), seeds pod-1 (0.19) by path coefficient analysis. Hence, for increasing the seed yield, direct selection of genotypes based on positively correlated traits will be more fruitful.

Title: Screening of brinjal lines to high salinity levels
Abstract: A pot experiment was conducted at the Sher-e-Bangla Agricultural University, Bangladesh during the months of November 2012 to April 2013 for screening the salt tolerant brinjal lines. Ten lines coded from V1 (Line-1) to V10 (Line-10) were executed under different salinity conditions (S0: Control; S1: 12dS/m and S2: 16 dS/m) following completely randomized design (CRD) with three replication. Maximum yield was provided by V1 and V6 (2.4 kg/plant) in 12 dS/m salinity level and V6 provided the maximum yield (1.3 kg/plant) which was closely followed by V1 (1.2 kg/plant) in 16 dS/m salinity level whereas 4.1 kg/plant and 3.8 kg/plant from V6 and V1 respectively in control. From the current study it can be stated that V6 and V1 lines were the best lines to grow in the highly saline affected areas in Bangladesh but varietal development form promising line and further field trials in different areas is recommended.

Title: In vitro regeneration potentiality of some Brassica genotypes
Abstract: Ten genotypes of Brassica, from three different groups of species, namely Tori-7, Kallyania, Sampad, Sonali (each from Brassica campestris), BARI sarisa-7, BARI sarisa-8 and MM-20-3 (each from Brassica napus), Rai-5, Shambal and Daulat (each from Brassica juncea) were selected to observe their in vitro regeneration potentiality using stem segment as the explants. Investigations on regeneration of these ten genotypes were accomplished with callus induction, maintenance of calli, organogenesis and finally plantlet regeneration and subsequent their establishment in the field condition. Among the varieties, BARI sarisa-8 showed the highest response in all aspects. Callus induction was highest in BARI sarisa-8 (99.60%) and lowest in Sonali (92.40%). Time required for shoot initiation was minimum in BARI sarisa-8 (21.12days) while it was maximum in Kallyania (25.12days). Number of shoots per callus was highest in BARI sarisa-8 (2.502) and lowest in MM-20-3 (1.208). Number of rooted shoots was highest in BARI sarisa-8 (55.56%). Survival rate of regenerated plantlets was highest in BARI sarisa-8 (80.00% in pot and 75.00% in soil) while the same was lowest in Kallyania (61.11% in pot) and in BARI sarisa-7 (30.00% in soil).

Title: Agrobacterium-mediated genetic transformation in Brassica species
Abstract: An efficient and reproducible protocol for the production of transgenic Brassica plants was developed by inoculating hypocotyl explants with Agrobacterium tumefaciens strain LBA4404 carrying a binary vector pBI121, which contains selectable marker gene nptII conferring resistance to kanamycin and the GUS reporter gene. The transformation experiment was performed by optimizing two important parameters: preculture period and co-cultivation period. Infection was most effective when explants were precultured for three days (68.75% GUS positive) and co-cultivated for three days (82.92% GUS positive) with Agrobacterium. Among the varieties, BARI sarisa-8 showed the highest response to GUS assay (64.38% GUS positive). Callus induction was highest in Rai-5 (10%) and three day period of preculture and co-cultivation (12.33 and 13.33%, respectively). Transformation percentage was also highest in Rai-5 (4.75%), and three day period of preculture and co-cultivation (7.50 and 5.42%, respectively). Highest percentage (33.33) of root induction from transgenic shoots was observed in ½ MS + 0.5 mgL-1 NAA + 50 mgL-1 kanamycin + 50 mgL-1 cefotaxime. Among the varieties, BARI sarisa-8 produced the highest percentage (37.78) of rooted shoots.

Title: Effect of greywater irrigation on wheat and mung-bean production in clayey-loam soil
Abstract: Greywater is considered as a viable and alternative source of irrigation in many parts of the world. In Bangladesh, it is mainly the marginal farming community who use untreated urban greywater for irrigation. However, very few crop and soil specific investigations on greywater use have been carried out in Bangladesh. This study reports the results of two agronomic experiments carried out to quantify the effects of greywater irrigation on the production of two popular winter crops in Bangladesh i.e., mungbean and wheat. It also reports the status of the nutritional balance of soil due to greywater irrigation in two consecutive years i.e., 2012 and 2013. The experiment with each crop was conducted in random blocks replicating each of the six greywater treatments thrice. The results highlighted the fact that raw use of greywater was not beneficial for mungbean. On the other hand, second highest yield of wheat was obtained from the raw greywater treatment. Nonetheless, the highest crop yield was found when greywater (75%) was diluted with freshwater (25%) in a combined use. Crops irrigated with alum-treated greywater produced moderate yields. Considering the health risks associated with raw use of greywater, the alum-treatment of greywater appears to be a viable alternative to the farmers. It was found that unregulated use of greywater resource could lead to salinity problems in clayey loam soil. In particular, raw greywater irrigation was shown to be leading a buildup of P in the soil which could pose a potential environmental risk. This study recommends that crops good at up-taking phosphorus from the soil should be prioritized in greywater irrigation schemes.

Title: Aquaponics in Bangladesh: current status and future prospects
Abstract: country has excellent fish culture potentiality because of its abundant water resources. Currently aquaculture is being intensified in Bangladesh to meet the demand of fish protein for increasing population. Agricultural land is also being converted to other uses everyday that is creating pressure on natural resources. Lack of food security and food safety are also serious problems here. Aquaponics, as a combined system of recirculating aquaculture and hydroponics, is an innovative technology in Bangladesh which could contribute to addressing these problems. However, there is a lack of quantitative research to support the development of economically feasible aquaponic systems in the country. Although many studies have addressed some scientific aspects, there has been limited focus on commercial implementation. The analysis shows that in aquaponic system water use is minimum, fish and vegetable production per unit area is higher than the conventional aquaculture and agricultural systems. Therefore, aquaponics have ample scope of enhancement of sustainable food production, especially in adverse geographical context of Bangladesh.
