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...

peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

in order to study the effects of ga3and cacl2 treatments in resolve the problems of sweet pepper culture in ilam region (including small size fruits with sunscald and blossom end rot disorders), this study was carried out in ilam university in 2012. for that, ga3 (50 mg/l) and cacl2 (0.5%) treatments were sprayed at two (fruit set and 15 days thereafter) and three (fruit set, 10 and 20 days the...

the level of self-compatibility of the 48 pre-selected apple cultivars, using their own pollen, the genetic capacity of flowering, flower-fruit conversion ratio, multiple fruit fall and bearing preservation during 4 successive biological growth stages were examined through two main treatments of self and cross pollination, in horticulture research station of kamalshahr in karaj (iran). the frui...

The influence of harvesting date on some physicochemical properties of nectarine (Prunus persica var. Red gold) fruit including fruit weight, pigment content, total carbohydrate, total phenol and antioxidant activity were studied. Fruits were harvested in four different stages; a) two weeks after fruit set, b) pit hardening, c) three weeks after pit hardening and 6 weeks after pit hardening. Re...
