Abstract:

This study aimed to evaluate the effect of rootstock age and grafting season on the graft success and initial growth of ‘Tainung No.2’ papaya in nursery. The experiment was conducted using an experimental Randomized Complete Block design with factorial scheme 4Ax2B, four blocks and 15 grafted plants per experimental unit. Factor A represented 4 levels of rootstock age (1, 2, 3 and 6 months) and factor B, two grafting times (May, September). The findings showed that rootstock age and grafting season had the significant effect on all the parameters: Time required for take, percentage of graft take, sprout length of scion, number of new leaves. The youngest age of rootstock (1-month) achieved the best results. Grafting in May achieved better results than in September. The best combination was of 1-month-old rootstock and grafting time in May with the minimum time required for take (8.4 days), the highest percentage of graft take (96.7 %), the maximum sprout length of scion (3.9 cm), and maximum number of new leaves (3.1 leaves). Therefore, this combination should be recommended for papaya propagation through cleft grafting
