Seed germination in Citrullus lanatus. Part 1. Effect of white light and growth substances on germination

Year: 1982

Type: article

Abstract: Germination of Citrullus lanatus seed is inhibited by white light. The nature of the light inhibition resembles that of a low-energy reaction. Removal of the outer seed structures, especially the membrane enveloping the embryo, overcomes the inhibitory effect of light. Gibberellic acid slightly reverses the inhibitory effect of light while kinetin and particularly ethrel strongly promote the germination of seed in white light. Die kieming van Citrullus lanatus-sade word deur witlig gerem. Die aard van die remming stem ooreen met die van ’n lae-energie-reaksie. Verwydering van die saadomhulsels, veral die vlies wat die embrio omring, hef die remmende invloed van witlig op. Gibberelliensuur hef tot ’n geringe mate die remmende invloed van lig op terwyl kinetien en veral ‘ethrel’ die remmende invloed van lig grootliks ophef.
