Gurevitch, Jessica, Samuel M. Scheiner, and Gordon A. In subnormal season alternate plant could be removed to reduce density to half is desirable. Crop stems are thinner, and due to more height crop is more subjected to lodging. Inter- and intraspecific Competition in Plant Communities can also affect population growth measures such as survival and fecundity. Frequency is highly influenced by the size and shape of the quadrats used. Agricultural Biotechnology: A range of tools, including traditional breeding techniques, that alter living organisms, or parts of organisms, to make or modify products; improve plants or animals; or develop microorganisms for specific agricultural uses. The metapopulation concept, originally developed for animals, can be applied to plant populations that are connected by gene flow but that are also subject to rapid extinction by disturbance. The mating or crossing of two plants or lines of dissimilar genotype is known as hybridization. In case of safflower there is remarkable adjusting capacity to plant density. However it is desirable to have plant density between 50 to 100 thousands ha.
