Growth and Development of Radish (Raphanus sativus, L.) Under Selected Light Environments

Plants of radish (Raphanus sativus L.) were grown under selectedlight conditions in controlled environmental chambers in orderto monitor the role of photoperiod, irradiance level and inputlight energy in plant development. Results indicated that thedaily input of light energy was the most important light factoraffecting leaf development while photoperiod and irradiancelevel had the major influences on storage organ development.Distribution of assimilates to leaves and storage organs variedunder different light regimes with long photoperiods and highirradiances producing the largest storage organs. Once initiated,the rate of storage organ growth was similar under all testedlight environments.
