Genetic divergence among 46 ash gourd genotypes from different origins was investigated to select the parents for hybridization using Mahalanobis D 2 statistics. Though the genotypes grouped into seven clusters, the pattern of distribution of the genotypes into different clusters were random indicating that the geographical isolation was not always related to genetic diversity. Characters like ...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

Sixty genotypes of ridge gourd (Luffa acutangula Roxb.) were collected from different locations of Bangladesh and were used to study their variability, character association and genetic diversity. Seventeen traits studied, of these, eight showed high heritability (over 80%). Correlation coefficient study indicated that yield per plant had highly significant positive relationship with the number...

to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...

the effect of shoot pruning (2, 3 and 4 branches per plant) and fruit position selection (on main branch vs on main and lateral branches) on yield and qualitative characteristics of two greenhouse grown pepper (capsicum annuum l.) cultivars (torkal and paramo) was studied through a factorial experiment arranged in a completely randomized block design, of three replications. results indicated th...

The objectives of this experiment were to determine the effects of different application rates of an enzyme hydrolyzed animal protein biostimulant (Pepton) compared to a standard application rate of a biostimulant derived from seaweed extract (Acadian) on plant growth parameters and yield of gold cherry tomatoes (Solanum lycopersicum L.). Biostimulant treatments were applied starting at 15 days...

BACKGROUND AND AIMS Allocation of resources to floral traits often declines distally within inflorescences in flowering plants. Architecture and resource competition have been proposed as underlying mechanisms. The aim of the present study is to assess the relative importance of resource competition and architectural effects in pollen and ovule production on racemes of Hosta ventricosa, an apom...

Rates of fruit drop and remaining fruited pan icles were monitored in the field for 96 days beginning on April 1, 1983. More than 90% of total fruit drop occurred within the first 4 wk, and final fruit set was 0.61%. Per centage of fruited panicles remained constant for the first 3 wk, decreasing sharply to 40% by the 6th week, and ending at 11.7% at harvest. Of the fruit which reached maturity...
