In this study scion of Thompson seedless grape cultivar was grafted on three local cultivars (Chav-ga, Rash-meri and Tre-rash) rootstock by wedge grafting in 2021-2022, were made manually the 15th Febrywary using one-year old cuttings ( rootstock). Growth parameters such as shoot length diameter, dry weight vegetative growth, number leaves showed significant...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...

the objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘camarosa’ strawberry (fragaria × ananassa duch.). the strawberry plants were sprayed with boric acid at 0 (control), 50 and 100 mg l-1 at 30 days after planting. in general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

abstract mango is one of the most important tropical fruits in iran and salinity is an important problem to mango production in ‘hormozgan’ province and other mango growing areas in iran. at present experiment the effects of saline irrigation water of different sodium chloride concentration on vegetative growth and ion content of mango was evaluated. treatments comprised two type of cultivars (...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...

Females of woody dioecious species usually devote more resources to reproduction than males. This may lead to a decrease in female survival and growth. The costs of reproduction, however, can be lightened through a number of mechanisms, as for example avoiding the temporal coincidence of reproduction and vegetative growth. The aim of this study was to evaluate whether males and females of P. le...

The vegetative performance of four nectarine tree scion/rootstock combinations, with varying growth capacities, were analysed in the Spring after the canopy:root ratio was dramatically reduced by severe pruning in the dormant season. We anticipated that severe pruning and reduction of the shoot:root ratio would mitigate known root water supply limitations related to the various rootstocks and d...

Irregular fruit production across successive years is a major issue that limits the profitability of most temperate and tropical fruit crops. It is particularly affected by the reciprocal relationships between vegetative and reproductive growth. The concept of the costs of reproduction is defined in terms of losses in the potential future reproductive success caused by current investment in rep...
