pears (pyrus spp.) belongs to the rosaceae family, which have been cultivated formore than 3000 years. pears are among the most important fruits in all the temperateregions in about 50 countries of the world. the objectives of this study were to classifypear genotypes based on qualitative and quantitative characteristic and determination oftheir genetic distance. evaluation of genetic diversity...

Based on the importance of drops' behavior in liquid-liquid extraction, the maximum sauter mean drop diameter has been investigated and correlated in a counter-current spray extraction column with two chemical systems. Spargers were set of nozzles in all experiments. Studying the effects of several parameters on drops size, some correlations were estimated by the last available version of softw...

effect of different fruit position on postharvest quality of f1 hybrid redfleshed watermelon hi-u 16 was examined. in this study only one main vine was trained and maintained. the plants were allowed to set three fruits naturally at the first (8th - 11th nodes), second (13th - 16th nodes) and third (18th - 21th nodes) position. fruits were harvested at 35 days after anthesis. fruit weight, diam...

apricot (prunus armeniaca), palys an important role in fruit production industry in iran. irregular set of fruit, caused by either sterility of flower organs or incompatibility has been the main problem in apricot production over the years. in this study, it has been attempted to determine these phenomena for four apricot cvs. namely ‘shahroodi’, ‘nasiri’, ‘jahangiri’ and ‘noori’ through the me...

Pear (Pyrus spp) is an important fruit crop, grown in all temperate regions of the world, with global production ranked after grape and apples among deciduous tree crops. A high-density linkage map is a valuable tool for fine mapping quantitative trait loci (QTL) and map-based gene cloning. In this study, we firstly constructed a high-density linkage map of pear using SNPs integrated with SSRs,...

In Japanese pear, the application of GA3+4 during the period of rapid fruit growth resulted in a marked increase in pedicel diameter and bigger fruit at harvest. To elucidate the relationship between pedicel capacity and fruit growth and to determine the main factor responsible for larger fruit size at harvest, fruit growth and pedicel vascularization after GA application were examined and the ...

In the present investigation, an attempt has been made to evaluate the genetic variability of yield contributing characters, and the genetic diversity in forty-four genotypes of okra collected from the IIHR, Bangalore, India. Analysis of variance indicated significant differences among the genotypes for different morphological characters. High GCV and PCV were observed for plant height, inter-n...
