摘 要:Coffee cultivation on dry area lately faces more often drought condition because of global warming effect. One effort to solve the problem is by using tolerant clones or varieties as the rootstocks. The aim of this research is to observe influence of BP 308, BP 409, and Exelsa as rootstocks, on growth, yield and bean quality of BP 409, BP 534, BP 936 and BP 939 clones as scions. The research was conducted in Temanggung district of Central Java, Indonesia, using randomized complete block design with 5 replications 10 plants per replication. The result showed that rootstock influenced stem height and number of branches, leaf relative water content (RWC) during dry season, but not stem diameter. BP 308 and BP 409 rootstocks supplied water more than Exelsa, it seem RWC scion on both rootstocks were higher (82.0%) than that of Exelsa (80.0%). Exelsa rootstock cause scion grow more slowly, so bean yield was lower than on BP 308 and BP 409. Yield accumulation until 4 years old on Exelsa was 55% to BP 308, and 52.2% to BP 409 rootstock. Yield of BP 939/BP 308 and BP 409/BP 409 (scion/rootstock) tend to the highest. Rootstocks did not influence percentage of normal and abnormal beans and the outturns. Bean outturn was more influenced by clones. Exelsa rootstock improves caffeine content, body, astringent and bitterness characters of scion cherries, but decreases fragrance and aroma characters of scion yield. It is concluded that farther taxonomical relationship of rootstock, their influence on scion growth, yield and cup test characters are stronger.
