Histology and Physiology of BPM1 Clones with Different Exploitation Systems

Abstract

This research aimed to study the characters of histology and physiology of BPM1 rubber clones to obtain the right exploitation system in increasing production in accordance with the character of the clones. The research results are expected to serve as a useful technology package which can be applied not only in the community rubber plantations but also in private as well as government large rubber plantations. The study was conducted in the rubber plantation of PT Perkebunan Nusantara III (Persero), Deli Serdang, North Sumatra, from 5 April to 28 December 2014. This study used a randomized block design with exploitation systems as the treatments, and each treatment was repeated three times. The exploitation systems employed were: tapping system (P) with four levels (P₁ : S/2 d3 BI-1,
