Frost damage to the flowers and early developing fruits is one of the most limiting factors in almond cultivation regions of the world. This study was undertaken to understand almond response to frost damage concerning ion leakage in order to develop a criterion for the selection of frost-resistant cultivars in field experiments. In this work, 60 almond cultivars and genotypes on the basis fros...

Changes in freezing injury percentage, lipid peroxidation (malonaldehyde formation), antioxidant enzymes activity and proline content were monitored in the leaves of olive cvs. ‘Fishomi’ and ‘Roughani’ under diff erent freezing temperatures (-5, -10, -15 and -20°C for 10 h). Th e results showed that freezing injury (determined by electrolyte leakage analysis) and malonaldehyde (MDA) content of ...

abstract the aim of this experiment was the study of freezing tolerance of bellis perennis under controlled conditions and were arranged in a completely randomized design with three replications. plants after sowing and grow in the bed, at the middle of autumn (after hardening in natural conditions), in the 7-8 leaf stage put on the thermogradiant freezer with the 12 freezing temperatures (0,-2...

A greenhouse experiment was conducted to evaluate the freezing damage in some pistachio rootstocks by ion leakage and pH changes of leaked solution. A factorial experiment was carried out in randomized block designs (RBD) with three factors: Temperature (A) including 4 ̊C, 0 ̊C, -2 ̊C, -4 ̊C, -6 ̊C, Time (B) including 3, 12, 24h , and Rootstock (C) including P. vera cv 'Badami Zarand' (V13) and 'Sar...

the pomegranate fruits of cvs. malas yazdi and malas ashkezar were immersed in sa (1 and 2 mm from source of acytyl salicylic acid) for five minutes, in ja (0.3 and 0.4 mm from source of n-propyl dihydrojasmonate) for fifteen minutes, in cacl2 (1 and 2%) for five minutes, and in distilled water for five minutes as control. then, the fruits were stored in cold storage at 1.5±0.5ºc and 85±5% rela...

In order to evaluate the effects of seed priming with salicylic acid (SA) (0, 2, 10, and 20 mM) to increase salt tolerance (0, 50, 100, 150, and 200 mM NaCl) in medicinal plant Dracocephalum moldavica at seed germination, an experiment was conducted as factorial in a completely randomized design with four replicates. The assessed parameters included germination percentage and rate, len...

due to physiological disorder, primary bud necrosis (pbn) in grapevine is a great problem in vineyards, resulting in reduced yield. primary bud necrosis (pbn) is physiological disorder resulting in the death of the primary bud. the present study conducted through a light on this critical problem in a vineyard of cisakht region. a factorial experiment with three levels of cold temperature (-10, ...
