Effect of Plant Hormones & Micro Nutrients on Fruit Production: A Review
Abstract
The plant growth regulators are chemical compounds, which can regulate some important metabolic activities in plants. They influence on growth and development of plants, which influence the increase in yield, quality of product, flowering and some other parameters. Plant growth regulators include auxins, gibberellins, cytokinins, ethylene, growth retardants and growth inhibitors. Production of low quality fruits is a common experience therefore, to improve the yield and quality of fruit crops application ofgrowth regulators is one of the important production strategies. Application of micronutrients and growth regulators applied fifteen days after fruit set was more effective in improving fruit quality as compared to thirty days after fruit set. The pomegranate plant continues to bear flowers irregularly once, twice or thrice in a year, depending upon germplasm, agro-climatic conditions and management practices. It produces a low yield of inferior quality with non-synchronized maturity. To avoid this, flower regulation is practiced to encourage prolific harvest at specific time depending upon rainfall/irrigation facilities, pests and diseases incidence and market demand. Investigated research areas – Moisture stress, plant growth regulators, nutrient and canopy management (training, pruning and thinning) are major horticultural interventions which influence flowering. Although, many studies have been conducted in different countries to induce profuse flowering with improved sex ratio, fruit set, retention and ultimately high quality fruiting in desired season
