Uji Kompabilitas Sumber Mata Entres dan Batang Bawah terhadap Pertumbuhan Mata Tunas beberapa Klon Tanaman Karet (Heavea Brasiliensis Muell. Arg.)

Abstract

This study aims to determine the compatibility of eye and under eye sources on the growth of some rubber clones, Avros 2307, GT 1, PB 330, PB 260, IRR 5, and RRIC 100. This research was conducted in Pergajahan village, Bintang Bayu Kab. Serdang Badagai with altitude of approximately 14 m from sea level, tofography and alluvial soil types. This research was conducted on March-June 2015. This research uses factorial randomized block design (RAK) consisting of two treatment factors. The first factor of rootstock (B) consists of 3 levels: B1 = afros 2307, B2 = GT 1, B3 = PB 330. The second factor of entres (E) sources consists of 3 levels: E1 = PB 260, E2 = IRR 5 , E3 = RRIC 100. From the results and discussion of this research it can be concluded that the most comparative rootstock clones are clones GT1 and for clones entres are clones PB260 and for the highest compatibility between rootstock with entres clones GT 1 with PB 260 on the growth of rubber clones eye buds (Hevea Brassiliensil Muell.Arg.).
