Role of auxin in horticultural fruit crops

Abstract

As we know auxins were the first class of plant hormones to be discovered that use to kill weeds, promote growth and fruit quality of particular plant.in this review paper I have compile the summary of Auxin as important hormone required to carry any essential function in plant viz., delaying, early maturation, help in rooting etc. I have categorized crop in accordance with role of auxin with tropical and temperate crops, which I hope could help scientist for further breeding programme, to acknowledge the role with its pros and cons. In mango it mainly influence the girdling effect, fruit repining process, and in grape it helps in the maturation and quality maintenance of berries on the other hand in apple with the appropriate concentration it triggers the production of ethylene which eventually promotes ripening accompany it helps in the translocation of calcium which maintain the fruit quality. In guava auxin is immensely used in the form IAA and IBA which operates as a rooting hormone in this crop to hasten the growth during layering on the other hand in pear and peach its application influence the growth of primary and secondary shoot.
