Changes in physicochemical attributes of sweet pepper var. 'BARI Misti Morich-1' during fruit growth and development were studied. Capsicum flowers were tagged on the day of anthesis and fruits were harvested at three days interval started on 33 days after anthesis (DAA) until 48 DAA, when turned to light green colour. Length, diameter, and weight of fruits were linearly increased from 33 DAA to 48 DAA. Dry matter content, TSS, firmness, and shelf life of fruits were also gradually increased with lengthen the harvesting time from flower anthesis and reached from 5.1 to 7.3%, 4 to 5%, 7.1 to 14.5 kgf cm -2 and 9.6 days to 21.3 days, respectively, from 33 DAA to 48 DAA. However, ascorbic acid content of fruits was sharply decreased from 68 to 56 mg/100g from first harvest to last harvest, respectively. Hue angle declined with time while chroma and lightness values increased with fruit maturity. Considering all physical and nutritional characteristics and shelf life along with sensory evaluation scores, fruits of BARI Misti Morich-1 was found suitable to harvest after 45 days of anthesis, when they attained length 12.2 cm, diameter 8.8 cm, and weight 191g. Moreover, fruits were crispier, glossy with attractive colour and flavour and contained 58 mg/100g ascorbic acid at this maturity stage.
A set of 9x9 half diallel cross comprising of promising genotypes was studied to analyze the inheritance pattern of yield components in tomato. Haymans analysis of variance (ANOVA) indicated importance of both additive and nonadditive genetic components for all the thirteen yield contributing characters. The ANOVA showed unidirectional dominance, asymmetrical gene distribution and residual dominance effects for all the characters studied. Five out of the thirteen characters viz., number of flowers/cluster, individual fruit weight, fruit breadth, number of locules and number of seeds/fruit followed the simple additive-dominance genetic model. The rest of the characters showed non-allelic gene interaction or epistasis. P6 had most of the dominant genes for both number of flowers/cluster and number of locules, while P3 contained most dominant genes for individual fruit weight and P5 possessed that for both fruit breadth and number of seeds/fruit. The estimates of components of variance demonstrated involvement of both additive and dominant components in the inheritance of all those five characters. The distribution of dominant and recessive genes was equal in the parents for only fruit breadth. There was drastic influence of environment on these characters following simple additive-dominance genetic model except fruit breadth.Bangladesh J. Agril. Res. 41(2): 335-344, June 2016
Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cutoff conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16
Four bottle gourd varieties and lines (V1: BARI and three pruning stages (P1: Pruning at two vine stage, P2: Pruning at 3 vine stage and P3: Pruning at 4 vine stage) were implied to observe the effect of pruning on the maximization of vine production in bottle gourd. V4 produced maximum number of vine (117.2/plant) and highest vine yield (10.2 t/ha) among four varieties while P3 produced maximum number of vine (109.2/plant) and highest vine yield (9.1 t/ha) among three pruning techniques. The maximum number of harvested vine (118.0/plant) and highest vine yield (10.73 t/ha) was found from V4P3 which was statistically followed by V4P1 and the lowest vine yield was recorded from V2P1 (6.62 t/ha). LS 0026-5-3 along with pruning of terminal shoots four vine stages can be recommended for better vine production in bottle gourd for use as leafy vegetable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
