The tapetum on the basis of its behaviour is divided into two main types: 1. Amoeboid 2. Secretory Tapetum. Type # 1. Amoeboid or Invasive or Periplasmodial Tapetum: This type of tapetum is seen in Alisma, Butomus, Tradescantia, Typha, etc. where, the tapetal cells fuse among themselves to form a tapetal periplasmodium. The protoplast of the fused tapetal cells move [...]
Self-incompatibility system can be divided into two basic groups: 1. Heteromorphic Systems 2. Homomorphic Systems. Group # 1. Heteromorphic Incompatibility: This incompatibility refers to those plants where the same species produces more than one morphological types of flower, where the relative length of the style (distyly and tristyly) and stamens differ. In distyly the plants produce two forms of flowers, [...]
