Gametophytic Apomixis,d anomaly of reproduction is “amphimixis”, i.e., sexual reproduction. Orginally, Winkler (1908) defined apomixis in a wider sense, including vivipary, pseudovivipary, and other forms of vegetative propagation such as bulbils, runners, rhizomes, etc. This broader definition is now rather rarely used.作者: 話 時(shí)間: 2025-3-23 01:27
Role of Polyploidy in Reproductive Organs and Tissues, including reproductive tissues, have been reported, and the connection between nuclear size and trophic activity of the cell has been stressed (references in Schnarf 1929, Tischler 1944, Maheshwari 1950).
