Abstract
The aim of the present paper Was to test the value of various plant extracts (yeast barm, mature walnut embryos, coconut meal, young spinach leaves and tomato juice) used as the complementary elements of White's mineral nutrient for the culture in vitro of generative apices of winter wheat, rape and wetch. The results showed that the generative apices of investigated planits had various nutritive requirements which point to the necessity of a careful selection of a specific nutrient for particular plant material.
