Effet de l'alimentation en eau sur quelques caractères morphologiques et anatomiques des feuilles de soja (Glycine max (L.) Merrill)

Plant Morphological and Biochemical Responses to Field Water Deficits

“…That trait is believed to be achieved through osmoregulation (1). A variety ofmorphological and biochemical characteristics may contribute to the expression of osmoregulation in drought-tolerant genotypes (2,18). Although the mechanism of osmoregulation is complex, the adaptive ability to maintain membrane integrity during long periods ofwater deficit may be an essential biological trait for drought tolerance.…”

“…Thus far, two striking differences in leaf glycerolipid compo-PLANT RESPONSES TO WATER DEFICIT (18). Quisenberry et al (15) have already shown that maintenance of leaf turgor is essential for cell elongation in photoperiodic strains of cotton; and that strain T25 exhibits a higher number of vascular bundles in petioles than strain T185 (16).…”

Ultrastructural and Histochemical Changes in Glyphosate-Tolerant Soybean Leaves Exposed to Glyphosate

“…Metcalfe and Chalk (1950) investigated several anatomical characteristics of the family and genus, referring to Glycine max by describing the disposition of vascular bundles of petiole and Fisher (1967) described the paranervural parenchyma in the mesophyll. Anatomical studies were conducted regarding variations in leaf thickness and stomatal frequency with factors such as gas exchange rate (Dornhoff & Shibles, 1976), water stress (Vidal & Pognonec, 1984), different nitrogen concentrations and irradiance levels (Sims, Seemann, & Luo, 1998).…”
