Associations between heat tolerance, water consumption, and morphological characters in Chinese cabbage

Variations with regard to heat tolerance, in terms of heading ability, and water consumption under high temperatures were studied in various Chinese cabbage (Brassica campestris spp. pekinensis Rupr.) varieties. Total water consumption did not differ among entries; however, heat tolerant varieties h...

Description
Summary:Variations with regard to heat tolerance, in terms of heading ability, and water consumption under high temperatures were studied in various Chinese cabbage (Brassica campestris spp. pekinensis Rupr.) varieties. Total water consumption did not differ among entries; however, heat tolerant varieties had greater water uptake than heat sensitive ones at the onset of head formation. Heat tolerant varieties also possessed thicker leaves, higher leaf sap electrical conductivity and chlorophyll content, and lower stomatal number. These characteristics appeared to facilitate water transport to the leaves and reduce transpiration, thus enabling the heat tolerant plants to maintain leaf turbidity during the heading stage at high temperature.
