self fertilization

Process of covering the flower or inflorescence by paper covers in order to avoid fertilization by external pollen. This makes only self pollination possib..

Incompatibility is the inability of functional male and female gametes to effect fertilization in certain plants. Incompatibility may be between 2 different species of the same genus, when it is called Interspecific incompatibility . If it is within the same species, it is called Intra..

:1. This is called the phenotypic ratio. Of the tall plants, 1/3 rd of the plants are homozygous for tallness and the remaining 2/3 rd are heterozygous. The heterozygous plants on self-fertilization again result in offspring that show 3:1 ratio for tallness to dwarf ness. Thus the genotyp..

While modern day farmers specialize in one agricultural sector, either dairy or growing potatoes, their predecessors kept a wide array of farm animals and planted many different kinds of field crops. Their farms were remarkably self sufficient, producing eggs, meat, milk, vegetables and g..

Mixed Farming - While modern day farmers specialize in one agricultural sector, either dairy or growing potatoes, their predecessors kept a wide array of farm animals and planted many different kinds of field crops. Their farms were remarkably self sufficient, producing eggs, meat, milk, ..

Crop yields remaining stagnant, pesticides polluting the eco-systems, increasing cost of fertilizers, reducing soil fertility, imbalance in host - parasite and predator - parasite relationships have pushed agriculture into dangerous mode. Scientists have looked back into the tec..

. Use of commercial hybrids invariably involves inbred plants as parents -which means parental purity is maintained by not allowing pollen from other varieties to fertilize. The success of hybrid crop and its heterosis is much dependent on purity of parents. As against this, hybridization..

. Thus for each U-235 atom the two Pu-239 atoms are produced. Thus in breeder reactors, the formation of fissionable nuclei is more in comparison to their respective consumption. Fissionable nuclides like U-235 or Pu-239 are also called fissile nuclides. On the other hand, non-fissionable nuclides ..

There are several varieties of rice available in the market. Similarly, there are many varieties of mangoes and brinjal. Each variety is unique in its colour, size, shape and taste. Thus, one type of plant has many varieties. A lot of research has gone into creating these varieties. They have been ..
