Salt stress is one of the main abiotic factors affecting castor yield. Wild resources can provide important insights for cultivated breeding. However, little known about how wild responds or adapts to salt stress. To understand physiological mechanisms tolerance in castor, morphological and responses two varieties, with contrasted were characterized under Seedlings exposed 0, 50, 100 mM NaCl. T...

theeffect of salt stress on the pysiological and biochemical responses of the seedlings of eight eucalyptus species viz. e. kingsmillii, e. tetragona, e. salubris, e. occidentali, e. microtheca, e. camaldulensis, e. globules and e. sargentii was analyzed. four month-old seedlings grown in greenhouse were watered by five levels of salt solution (0, 50, 100, 150 and 200 mm of nacl) in five replic...

TURKYILMAZ UNAL, B., L. Y. AKTAS and A. GUVEN, 2014. Effects of salinity on antioxidant enzymes and proline in leaves of barley seedlings in different growth stages. Bulg. J. Agric. Sci., 20: 883-887 The participation of antioxidant defence under mild and severe salt stress conditions (120 and 240 mM) on barley (Hordeum vulgare L.) seedlings in different growth stages, antioxidant enzyme (super...

We investigated the impact of arbuscular mycorrhizal fungi (AMF) on the morphology and physiology of two genders of the typical dioecious plant Populus cathayana under salt stress. We conducted a pot experiment containing seedlings of the two genders that were subjected to salt or non-salt and filled with soil that was either inoculated with Rhizophagus intraradices or not. The results showed t...

Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...

Salt stress is one of the most crucial factors impacting plant growth, development and reproduction. However, information regarding differences in tissue-specific gene expression patterns, which may improve a plant's tolerance to salt stress, is limited. Here, we investigated the gene expression patterns in tissues of Populus euphratica Oliv. seedlings using RNA sequencing (RNA-Seq) technology....

It is adopted mostly of the non-imaging spectrometer in current crop seedling monitoring, this method is greatly interfered by the soil background, makes it difficult to analyze the partial area nutritional status of the seedlings. In this study, we took advantage of merging the image with spectrum of the imaging spectrometer, to analyze the canopy, individuals, different size of leaves, charac...

Effects of brassinosteroids (BRs) on cucumber (Cucumis sativus L.) abiotic stresses resistance to salt, polyethylene glycol (PEG), cold and the potential mechanisms were investigated in this work. Previous reports have indicated that BRs can induce ethylene production and enhance alternative oxidase (AOX) pathway. The mechanisms whether ethylene is involved as a signal molecule which connected ...

The work reported here evaluates whether bacteria populating arid and salty environments can confer resistance in tomato and pepper plants to water stress. Plant growth-promoting bacteria that have ACC deaminase activity were isolated from soil samples taken from the Arava region of southern Israel. One of these strains, Achromobacter piechaudii ARV8 [Mayak et al., Plant growth-promoting bacter...

Acacia ampliceps (salt wattle), a leguminous shrub, has been introduced in salt-affected areas in the northeast of Thailand for the remediation of saline soils. However, the defense mechanisms underlying salt tolerance A. ampliceps are unknown. We investigated various physio-biochemical and morphological attributes of A. ampliceps in response to varying levels of salt treatment (200-600 mM NaCl...
