¬¬¬one of the most important limitations for selection of second crop in paddy fields in guilan is waterlogging in the second half of the year. for an evaluation of waterlogging effect (in adequate drainage) on canola yield, a lysimeter study was conducted implementing -10,-5,0 and +5 cm water level for 2,5,7 and 10 day durations at 3 plant growing stages namely: emergence, beginning of floweri...

Almond is one of the most important nut crops in Iran. Due to the suitable climatic conditions, Iran is one of the most important growing centers for wild and domesticated species of almond in world. Native genotypes typically are early flowering, due to late spring frost, often; they have been damaged. So frost damage to the flowers and early developing fruits is one of the most limiting facto...

The abscisic acid (ABA)-, stress-, and ripening-induced (ASR) protein is a plant-specific hydrophilic transcriptional factor involved in fruit ripening and the abiotic stress response. To date, there have been no studies on the role of ASR genes in delayed flowering time. Here, we found that the ASR from banana, designated as MaASR, was preferentially expressed in the banana female flowers from...

in order to study the effect of different concentrations of salicylic acid in two commercial apricotcultivars of shahrood namely ‘shahrood 41’ and ‘jaffari’, under cold stress, a factorial experiment wasconducted in a randomized complete block design with three replications in 2012 at the agriculturalresearch center of shahrood city. the test had four factors including: sa with three levels (0....

a pot experiment was carried out to determine the effect of foliage spraying of silicon (si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. a factorial experiment based on completely randomized design was conducted with 3 levels of si (0, 50 and 100 mg/l) and 3 levels of nacl (0, 100 and 200 mm) with 4 replications. at flowering stage, s...
