Abstract: | Seeds of Scurrula pulverulenta, a leafy mistletoe, germinatedon a simple nutrient medium, and addition of casein hydrolysate(CH) supported better growth of the seedlings. In either casethe seedlings developed haustoria which were comparable to thehaustoria formed in vivo inside the host tissue. On White'smedium (WM)+CH+indole-3yl-acetic acid (IAA) the embryo callusedand, subsequently, differentiated shoot buds and/or haustoria.On WM+CH+IAA+ kinetin the callused embryo did not differentiatehaustoria or shoot buds. However, on this medium, embryoidsdeveloped up to the heart-shaped stage. The effects of somecytokinins, coconut milk, and water-melon juice, on germination,proliferation of embryo, and differentiation of shoot buds fromthe callus were also studied. |
