Water stress caused by drought affects the productivity of sugarcane crop. A breeding alternative is selection drought-tolerant cultivars. The objective this study was in vitro screening cultivars tolerant to water using polyethylene glycol (PEG) as a stressing agent. Cultivars (cv) Mex 69-290, CP 72-2086, 79-431 and MOTZMex 92-207 were subjected different concentrations PEG 6000 (0, 3, 6 9% w/...

Drought is a major threat worldwide for crop production, especially due to the rapid climate changes. Current drought solutions involve improving irrigation system, rainwater harvesting, damming, cloud seeding, and changes of cultivation methods. Despite effective, each solution has economic, environmental, temporal drawbacks. Among all solutions, most inexpensive manageable method use drought-...

Plant salt tolerance is associated with a high rate of root growth. Although growth governed by cell wall and apoplastic pH, the relationship between these factors in elongation zone under salinity stress remains unclear. Herein, we assess pH- expansin-dependent extensibility, expansin expression salt-sensitive (Yongliang-15) -tolerant (JS-7) cultivars stress. A six-day 80 mM NaCl treatment sig...

abstract planting of olive (olea europaea l.) tree due to salt and drought tolerance and ever green habit increasingly is considered in urban landscape in recent years. the low resistance to cold has been a major problem in using this tree in temperate and cold zones. so, determination of frost resistance cultivars is one of the important measures for use of this tree in urban landscape. to eva...

Chromium (Cr) as a toxic metal is widely used for commercial purposes and its residues have become a potential environmental threat to both human and plant health. Oilseed rape (Brassica napus L.) is one of the candidate plants that can absorb the considerable quantity of toxic metals from the soil. Here, we used two cultivars of B. napus cvs. ZS 758 (metal-tolerant) and Zheda 622 (metal-suscep...

Cotton (Gossypium hirsutum L.) production in Oklahoma has more than tripled the last ten years. This increase cotton acreage Oklahoma, a region that traditionally produces winter wheat, led to increased incidences of 2,4 D contamination sprayers are used spray crops. is extremely sensitive D, with losses yield and ultimately profit producer cases drift or tank carryover. In this study, six cult...

Forms of aluminum (Al) present in the solution tropical and subtropical soils can cause toxicity rootstocks peach cultivars, impairing growth productivity. This be minimized by growing Al-tolerant cultivars. However, this is not sufficiently known, especially because plant breeding programs do always consider tolerance as a selection variable for genetic materials. The study aimed to (a) select...
