Effects of Pruning at Different Times of the Year on the Maturation Period and Fruit Quality of Pearl Guavas

Abstract: To regulate the maturation period of Pearl Guavas, improve their fruit quality and reap more economic benefits, pruning at different times of the year can encourage new shoots to blossom and produce fruits. The present study shows that if pruned in August or September guava trees blossom in October or November and their fruits ripen in March or April the following year. If pruned on 25th August, fruits ripen on 27th March the following year with the highest yield and good quality. Key words: pruning; pearl guava; maturation period; quality
