Allelopathy of Brassica. A review
Journal Title: Scientia Agriculturae - Year 2013, Vol 3, Issue 2
Abstract
Plant growth regulators also impart important role towards the higher yield of crops. Among different strategies, exogenous application of plant growth regulators (PGR’s) are involved in promoting plant growth and development under normal and stressful conditions. However, use of organic fertilizers and green manures, cover crops, smother crops and surface mulch is beneficial for soil health, but their use is uncommon. Allepathic crops are also a source of organic agriculture and their utilization can enhance crop growth and yield. Allelopathy is a naturally occurring phenomenon based on fact that organic chemicals (allelochemicals) release from the plants and enter in to the environment. Release of chemicals also occurred from different plants organs having positive or negative impacts on the growth and development of others plants, which are growing in natural environment. The beneficial and harmful chemical compounds are called allelochemicals, and their actions can be classified as secondary metabolites.There are numerous ways in which allelopathy affects the adjoining systems. It influences the vegetation pattern and diversity, seed decay is prohibited, enhance plant succession, hence, allelochemicals affect the plants to greater extent. Several chemicals are present in different kinds of soils and the plant materials effect the germination and growth of the other plants which are growing in the vicinity of that plants. Virtually, allelochemicals are components of all plant parts and target plants can be sprayed through foliar application.
