Sugar Accumulation along the Seminal Root Axis, as Affected by Osmotic Stress in Maize: A Possible Physiological Basis for Plastic Lateral Root Development

Screening of Maize Genotypes for Drought Tolerance Related Trait Variability

“…An inverse relationship between rooting depth and available soil water was reported in maize under field conditions (Dwyer et al, 1988). Earlier Ogawa et al, (2005) also reported declined root length and roots density in maize in water deficit environment. Eggball and Maranville (1993) reported that root weight and length of maize cultivars differed among genotypes.…”

Genotypic Variations in Responses of Lateral Root Development to Transient Moisture Stresses in Rice Cultivars

“…On the other hand, drought was induced using polyethylene glycol 6000 (PEG 6000) (4%, W/V) to attain -0.13MPa water potential. PEG has been reported to have no apparent toxic effects under wellaerated condition (Verslues et al, 1998;Raymond and Smirnoff, 2002;Ober and Sharp, 2003;Ogawa et al, 2005Ogawa et al, , 2006aOgawa et al, , 2006b) and hence, can mimic the drying effects of soil environment. Seven days after the onset of the moisture stress treatments, the seedlings of each genotype were transferred to their contrasting moisture stress treatments for another 7 days.…”

“…On the other hand, drought was induced by adding polyethylene glycol 6000 (PEG 6000) (4%, w / v) to attain a -0.13MPa water potential. Polyethylene glycol has no apparent toxic effects under wellaerated conditions (Verslues et al, 1998;Raymond and Smirnoff, 2002;Ober and Sharp, 2003;Ogawa et al, 2005Ogawa et al, , 2006aOgawa et al, , 2006b hence, can mimic the drying effects of soil environment. Seven days after the onset of the initial moisture stress treatment (7 DAS), the seedlings of each genotype were transferred to the contrasting moisture stress treatment for another 7 days (8-14 DAS).…”
