A pot experiment was conducted for the first time in Bangladesh, at the Horticulture Farm of Sher-eBangla Agricultural University, Dhaka during November, 2010 to July, 2011 to asses the adaptability of seven lisianthus (Eustoma grandiflorum) cultivars namely Micky Rose, Pink Rose, Azuma No Yosooi, Purple Edge Glass, Piccolo Blue, Mellow Purple and Royal Violet for commercial cultivation in Bangladesh. The experiment was conducted in a Randomized Complete Block Design with nine replications. Significant differences among cultivars were noted for all the attributes evaluated. The highest number of flowers (16.0/plant) was produced by Piccolo Blue and the lowest from Pink Rose (7.0/plant). All the cultivars in this study showed very good shelf life (12.0-25.0days) in normal condition. All the seven lisianthus cultivars performed satisfactorily as ideal cut flowers. Further work may be done to develop these as commercial cultivars in Bangladesh.

Five varieties viz., Caesar, Aymara, Ivory, Jewel, and Triticaca were in use for the study in Randomized Complete Block Design with five replications. Significant differences among cultivars were noted for all attributes evaluated. Variety 'Triticaca' had maximum stalk length and diameter, spathe length and breadth, spadix length, vase life and flowers per plant. Through present analysis it is noticed that, variety 'Titicaca' are exceedingly preferred because of its attractive flowers, excellent flower size, yield potentiality and long shelf life.

An experiment was conducted at Research and Development (Vegetable) Farm, Supreme Seed Company Limited, Mymensingh in 20th March to 14th June, 2013 to evaluate performance of eight snake gourd genotypes. Among snake gourd genotypes four were test hybrid viz. SG1001, SG1002, SG1003 and SG1004 (from the seven inbreed lines) and four were checks (three from local market and one from BADC) viz. SUPREMA, RUNNER, SURMA, ZUM LONG. Wide ranges of variability were found in the studied characters among the genotypes. Maximum total number of fruits was found from SUPREMA (235.3/plot) which was statistically similar to RUNNER (201.3/plot) while minimum from ZUM LONG (24.7/plot) that was used as check. SG1002 genotype provided maximum marketable yield (49.6 kg/plot) and minimum from ZUM LONG (30.7 kg/plot). SUPREMA, SG1002, SG1001 and RUNNER genotypes showed better performance in respect of number of fruits/plant, fruit length, individual fruit weight, yield/plot and some other characters. Flowering period was significantly correlated with yield contributing characters. Number of fruits/plant, total number of fruits/plot and individual fruit weight was significantly positively correlated with yield of snake gourd.  DOI: http://dx.doi.org/10.3126/ijasbt.v2i4.11302Int J Appl Sci Biotechnol, Vol. 2(4): 525-528

To find out the response of potted gerbera under different light spectrum wavelengths of solar radiation was carried out. Three gerbera cultivars viz. V 1 (red), V 2 (pink), V 3 (brick red) and seven
