This study evaluated the side-cleft grafting in native species of the genus ( L., Sw., and Jacq.) with BRS Kottanadan pepper cultivar as rootstocks (Experiment 1). The top-cleft grafting was evaluated in native species Aubl., , and with Balankotta pepper cultivar as graft using black pepper cv. Bragantina (Experiment 2). Black pepper cv. Bragantina autograft was considered as control. The rootstock showed initial incompatibility with the cv. Bragantina, with survival of about 34.8% (side) and 62.5% (top) and total inhibition of graft shooting. The side and top graft on resulted in 84.0 and 47.5% of survival, respectively. The JIP-test parameters indicated better photochemical efficiency in the species grafted using the method of side-cleft grafting. Finally, the initial compatibility was associated with greater survival, shooting, and better energy flow through the electron transport chain.
本研究评估了以BRS科塔纳丹辣椒品种为砧木，对（L.、Sw.和Jacq.属）本地物种进行侧裂嫁接（实验1）。以巴兰卡辣椒品种为接穗，以黑胡椒品种布拉甘蒂纳为砧木，对本地物种Aubl.、和进行顶裂嫁接评估（实验2）。黑胡椒品种布拉甘蒂纳自嫁接作为对照。砧木与布拉甘蒂纳品种表现出初始不亲和性，侧裂嫁接存活率约为34.8%，顶裂嫁接存活率为62.5%，嫁接苗完全抑制抽梢。在砧木上进行侧裂嫁接和顶裂嫁接的存活率分别为84.0%和47.5%。JIP测试参数表明，采用侧裂嫁接法嫁接的物种具有更好的光化学效率。最后，初始亲和性与更高的存活率、抽梢率以及通过电子传递链的更好能量流相关。
