Time of cutting collection, use the rooting fitorregulador and different types of grafts in the seedlings production of 'Roxo de Valinhos' fig tree

Abstract

This work aimed to develop a protocol of table grafting in 'Roxo de Valinhos' fig tree by bud method. The first experiment, woody cutting of the medium portion, with 20 cm of length, were collected of May, June, July, August and September. Table grafting was accomplished by bud method plate type (it cuts of 10 mm² among two buds of the cutting, bud interfering of same dimension, extracted of the green and swollen buds of the cutting apical portion). In the second experiment, the cuttings were collected in July, being accomplished table grafting by the bud methods, for different types: plate, normal "T", inverted "T" and window. After the insert of the bud, in two experiments, they were tied the bud with plastic ribbon, leaving the exposed of the bud. Half of the grafted cutting had its bases negotiated in 2000 mg L^-1 of IBA by 10 seconds and the other half stayed without treatment. The cuttings were buried in sand, under nursery with 50% of brightness. The 120 days after the grafting, the percentage of alive, sprouting buds, alive buds in taken root rootstocks and the medium length of the sprouting were evaluated. The table grafting is among of June to August, by normal "T" and the cutting treatment with IBA.
