Leaf responses to soil water deficits: comparative sensitivity of leaf expansion rate and leaf conductance in field-grown sunflower (Helianthus annuus L.)



Leaf responses to soil water deficits: comparative sensitivity of leaf expansion rate and leaf conductance in field-grown sunflower (Helianthus annuus L.)



Plant and Soil 153(2): 189-194



The leaf expansion rate (LER) and leaf conductance (g1) responses to soil water deficits in sunflowers Sungro 380 grown at Cordoba, Spain, were qualified under conditions of moderate (spring) and high (summer) evaporative demand. Soil water content, g1 and LER were measured in dryland (DRY) and daily-irrigated (WET) crops established on a deep sandy-loam (Typic Xerofluvent). There was no difference between g1 of DRY and WET plants in contrast with a highly significant difference in LER.
