The chemicals that regulates the plant growth, and which are also termed 'plant growth substancesââ¬â¢ are referred to as phytohormones. These are produced in extremely less concentrations within the plant. Hormones play a major role in regulation of cellular processes in plants in cells that are targeted locally and, when moved to other locations.
The formation of flowers, stems, leaves, development and ripening of fruit, shedding of leaves are also determined by Phytohormones. Plants do not have any glands that produce and secrete hormones and are different form animals. Instead, each and every cell has got the capacity of producing hormones. Plant hormones plays an important role in shaping the plant, time of flowering, affecting seed growth, senescence of leaves, the sex of flowers and fruits. The journal that publishes all the articles online in the topic of phytohormones is Journal of Steroids & Hormonal science. The unofficial impact factor for the Journal of Steroids & Hormonal Science is 3.125.
