18 Nov Application of Paclobutrazol in Alternate Bearing Fruit Crops
फल फसलों मे अनियमित फलन की समस्या में पैक्लोबुट्राजोल का अनुप्रयोग Biennial fruits bearing or Irregular bearing or Alternate bearing is serious problems in fruit crops leading to considerable decline in their fruits production potentials. Alternate bearing means "a condition at which high or optimum fruit production in on year or higher and certain year bear little or no fruit (off-year). Flower initiation is very important because it is the first step towards attaining fruit. Recent trials have clearly shown that while the extent (quantity) of flowering affects yields, time of flower emergence has a significant influence on time of fruit maturity. Early flowering clearly resulted in early fruit maturity, therefore, one method to manipulate flowering is to use the plant growth regulators particularly the growth retardants like paclobutrazol. Paclobutrazol is a member of the triazole plant growth inhibitor group that is responsible restricts vegetative growth and induce flowering in biennial bearing several fruit crops. Paclobutrazol (PBZ) is responsible for the induction and manipulation of flowering, fruiting and tree vigor in biennial bearing fruit crops. The application of paclobutrazol in the soil promotes flowering and increasing yield in many fruit crops. Besides reducing gibberellins level, paclobutrazol increases cytokinin contents, root activity, and C: N ratio, whereas its influence on nutrient uptake lacks consistency. It also affects...
