The growth rate of geometric growth is called relative growth rate or ‘efficiency index’. It is defined as all the changes that an organism goes through during its life cycle, right from seed germination to senescence. Cytokinins promote the growth of lateral and adventitious shoots and delay senescence. Save my name, email, and website in this browser for the next time I comment.

Plant Growth and Development for NEET 2020 Exam has been discussed in this video. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. 2. Learning the important concepts is very important for every student to get better marks in examinations. 1. Growth refers to the increase in size and number whereas development refers to an improvement of circumstances. Growth: It is a quantitative parameter and refers to an irreversible increase in size or weight of a cell, tissue or organ.Plants are capable of growing throughout their life due to meristematic tissues present in certain parts. There are a number of different offerings in the market, but to make them available at an affordable cost is the big question. Fundamental to this process are several growth regulators collectively called the plant hormones or phytohormones. growth and differentiation) is influenced by extrinsic factors (light, temperature, water) and intrinsic factors (genes and plant growth regulators).
