Cotyledon Shading and Seedling Growth of Pumpkin1
Year: 1981
Type: article
Abstract: Pumpkin ( Cucurbita moschata Poir, cv. Dickinson Field) seedlings were grown in the light, in the dark, or in the light with the cotyledons covered. Cotyledons kept in the dark or covered, lost a fourth of their dry weight to support axis tissue growth and were dead 25 days after planting. Dry weight of light-grown cotyledons decreased initially but by 25 days after planting equaled their initial dry weight. Dry weight of dark-grown axis tissue increased for 9 days and then remained constant. The weight of axis tissue of plants grown in the light at 25 days was 4-fold greater than axis tissue from plants whose cotyledons were covered. The data show that shading of the cotyledons dramatically affect the growth of the axis tissue of the young pumpkin seedling.
