Author(s): RK Jhade, AD Huchche and SK Dwivedi
Abstract: Citrus (Citrus spp.) is one of the main fruit tree crop grown in many tropical and subtropical regions in the world. Flowering is a cascade reaction consisting of several steps. Flower formation is a transition phase in the life cycle of a plant. Citrus species usually produce a large no. of flower over the year the floral load depends on the cultivar, tree age and environmental conditions. Flowering is the first of several events that set the stage for citrus production each year. It also influences the quality and quantity of fruits. The flowers and fruit of trees senesce when the concentration of auxin decreases and the concentration of abscissic acid (ABA) increases. Endogenous hormones and their balance play a modulating role in the mobilization of nutrients to the developing organs. Temperature, florigenic promoter, inhibitors, auxin, cytokinin, gibberellin, carbohydrates, amino acids, phenols, enzymes and genetic factors play important role in the floral induction of citrus. The elements and mechanisms whereby endogenous and environmental stimuli affect fruit growth are being interpreted and this knowledge may help to provide tools that allow optimizing production and fruit with enhanced nutritional value, the ultimate goal of the Citrus Industry. To obtain higher fruit yield during a particular period, the citrus (Nagpur mandarin) plants are given a resting period by which the natural tendency of the tree is altered with artificial means. It is done by withholding of water for about 30 to 40 days in advance of the normal flowering, root exposure and also use of chemicals is known as bahar treatment.
