Abstract:

In order to apply the interspecific grafting technique in coffee production, five years of field experiments were carried out to study the main agronomic characters and quality characters between C. canephora cv. Reyan No.3 (No Grafted) and C. canephora scion grafted on C. liberica var. Dewevrei No.16 rootstock (Grafted). The results showed that the plant height, stem diameter, crown width and longest primary branches length were higher in 1-year-old grafted trees, but the difference was not significant. The number of primary branches and the number of the longest primary branches node of the grafted were significantly bigger than that of not grafted. The fruit number per node was significantly higher in the not grafted in 2015, but there was no significant difference in 2014 and 2016. The dry-fresh ratio, weight of 100 beans, single plant fruits weight were not significantly different between the not grafted and the grafted. As the number of fruit nodes per grafted plant increased, the yield of grafted plants not significantly decreased. In summary, there were no effects on the yield and quality characters of grafted plants, the interspecific grafting could be applied in coffee production.

Key words: Coffea canephora Pierre ex Froehner, interspecific grafting, agronomic characters, quality characters
