The effect of temperature on growth and development of cultivars of radish (Raphanus sativus L. var. radicula Pers.) under summer conditions.

Abstract

During 1977, seven cultivars and strains were sown in glasshouses at temperatures of 10, 14, 17, 20, 23 and 26 deg C and harvested at five dates. Maximum leaf and dry-matter production occurred at 20 and 23 deg C, and maximum root growth initially at 20 and 23 deg C, but later at 17 deg C. Cultivar differences in rate of leaf and root growth were observed, and cultivar X environment interactions were apparent for leaf and root growth under summer conditions. The overall order of cultivars for leaf and root weight was similar to that for plants grown under autumn conditions [see PBA 47, 5915]; hence it is suggested that selection of plants for growing in winter could be performed during the summer.
