Test Tube Pollination 5. Stub Pollination 6. Intra-Ovarian Pollination 7. In Vitro Pollination 8. Use of Mentor Pollen 9. Elevated Temperature Treatment 10. Irradiation 11. Surgical Method 12. Application of Chemicals 13. Protoplast Fusion. Method # [...]
In this article we will discuss about the anatomy of anther. 1. Anther Initiation: The dynamics of anther development and differentiation depend on the co-operative interactions between cell populations. The anther normally consists of two lobes, each with two elongated microsporangia or pollen sacs. The anther lobes are fused together by the connective tissue (Fig 1.1). The filament connects the [...]
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, [...]
