Alternative oxidase (AOX) has been documented to mitigate the oxidative stress caused by abiotic stresses. However, it remains unknown how AOX regulates antioxidant system and photosynthesis under waterlogging. To address this issue, we used two watermelon (Citrullus lanatus L.) cultivars (waterlogging tolerant cultivar ‘YL’ sensitive ‘Zaojia8424’) as materials inhibitor salicylhydroxamic acid ...
Salicylic acid (SA) is a naturally produced compound and has been implicated to play important roles in defense of plants against diverse biotic and abiotic stresses. To understand how SA functions in the tolerance of cucumber (Cucumis sativus) to chilling stress, endogenous SA levels in two different cultivars with opposite chilling responsiveness were quantified. Membrane integrity, including...
Abstract: Temperature is one of the most important factors limiting the production and distribution of olive. Different olive cultivars show diverse responses to low temperature and so, the selection of cold tolerant cultivars is the most effective method to avoid frost damages. The main purpose of this study was to compare freezing tolerance of seven olive cultivars and to investigate the rel...
The effect o f paraq u a t on hydroxyl radical production , glutathione and ascorbate content, and glutathione reductase and superoxide dism utase activities was assayed in the to lerant “K w angkyo” and the susceptible “ H o o d ” cultivars o f soybean [Glycine max (L.) Merr.]. Seed lings o f both cultivars a t the fully expanded first trifoliate leaf stage were treated with paraquat at 0, 1,...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
Brassinosteroids (BR) regulate plant tolerance to salt stress but the mechanisms underlying are not fully understood. This study was to investigate physiological mechanisms of 24-epibrassinolide (EBR)'s impact on salt stress tolerance in perennial ryegrass (Lolium perenne L.) The grass seedlings were treated with EBR at 0, 10, and 100 nM, and subjected to salt stress (250 mM NaCl). The grass ir...
common vetch ( vicia sativa l.) an annual forage, belonging to the fabaceae family is one of the highly cultivated forage legumes in iran. drought stress is a serious adverse factor that limits plant growth and productivity, inducing a range of physiological as well as biochemical responses in plants. it may also lead to generation of oxygen activated species which in turn result in cell destru...
Scientific data on the hulled wheats is scarce. Therefore, changes in some physiological attributes including carotenoids concentration, antioxidant enzymes activity, malondialdehyde content (MDA), cell membrane stability index (MSI) and grain yield in a hulled tetraploid wheat (i.e. "Joneghan") and a durum wheat cultivar (i.e. "Yavaroos") in response to salinity and plant growth promoting rhi...
this study was carried out to investigation the possibility of using triadimefon (trd) in order to decrease the adverse effects of salt stress on medicago plant. triadimefon is a member of triazol compounds which enhances stress tolerance through physiological processes. two cultivars of medicago sitiva including hamedani and yazdi were used in this study. plants were treated with 1, 2 and 4 mg...
