In this article we will discuss about the process of cybrids production. These are cytoplasmic hybrids. In cybrids, nucleus of one parent and cytoplasm of both the parents constitute cytoplasmic hybrids. More precisely, cybrids can be accomplished by fusing protoplast derived from one of the parent plants with enucleated protoplast of other. Cybrids can also be obtained through various other [...]
In this article we will discuss about:- 1. Anther Culture Technique 2. Microspore Culture 3. Diploitization 4. Anther Vs. Pollen Culture 5. Plant Regeneration 6. Characteristics of Microspore Derived Plants 7. Ontogeny of Androgenesis. The term haploid refers to those plants which contains gametophytic number of chromosomes. Anther/pollen culture mediated production of haploid plants approves the concept of totipotency. Guha [...]
Plant culture media contains: 1. Macronutrients 2. Micronutrients 3. Adjuvant 4. Carbon Source. 1. Macronutrients: Macronutrients or macroelements are basically inorganic salts. There are six major elements indispensable for growth of plants—nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. Carbon, hydrogen and oxygen are obtained from the environment. In culture media concentration of these elements are well balanced depending on the [...]
