Certainly, I would be happy to provide an article on plant growth regulators in pea.
Pea (Pisum sativum) is an important legume crop that has been cultivated for thousands of years. In order to increase yield and quality of pea crops, plant growth regulators (PGRs) can be used. PGRs are chemicals or compounds that regulate plant growth and development, and they can be used to modify plant growth and production in a variety of ways.
One commonly used PGR in pea production is gibberellic acid (GA), which stimulates growth and enhances cell elongation. GA can be applied to pea plants both before and after flowering, and can increase pea yield and the number of pods per plant. Additionally, GA treatment has been found to improve the quality of pea pods, increasing their length and weight.
Another PGR that is used in pea cultivation is auxin, which helps regulate root development and hormone balance in plants. Auxin can be applied as a foliar spray or through soil application, and has been shown to increase lateral root formation and root biomass in pea plants. It can also improve the resistance of pea plants to environmental stressors, such as drought or nutrient deficiency.
Cytokinins are another class of PGRs that are used in pea production. These hormones play a key role in cell division and differentiation, and can help promote shoot growth and branching. Cytokinins can be applied to pea plants through foliar spray or soil application, and have been shown to increase pea yield, pod size, and shoot biomass.
Finally, ethylene is a plant hormone that influences a variety of physiological processes in plants, including ripening and senescence. Ethylene can be used to control the maturity and harvest time of pea crops, and can also help reduce the incidence of pod splitting. Ethylene can be applied as a spray or through exposure to gaseous ethylene, and has been found to increase the yield and quality of pea crops.
In conclusion, the use of plant growth regulators in pea production can have a significant impact on yield, quality, and overall crop performance. By carefully selecting and applying PGRs, farmers and growers can optimize the growth and development of pea crops, leading to higher yields and more profitable harvests.
