The Effect of Agar Concentration on the Growth of Cotyledon Tissue of Pumpkin in vitro

Sibila Jelaska ; Hrvatska

Abstract

Tissue fragments of cotyledons of pumpkin (Cucurbita pepo L.) were cultivated on Heller’s nutrient medium — in artificial light (485 ± 45 lux) as well as in darkness — and the effect of the agar concentration (0%, 0,5%, l'°/o, and 1,3%) on their growth rate was investigated.
Both in light and darkness the highest increase of fresh and dry weight of the tissue fragments has been obtained with 0,5% agar concentration, the growth rate being iin light always much bigger than in darkness.
