橡胶树胶木兼优品种热垦525适应性试种研究
Trial Planting of Timber/Latex Clone Reken 525, Hevea brasiliensis
摘要
Abstract
Eleven trials have been undertaken in Hainan, Guangdong and Yunnan Province aimed to breed latex-timber clones. The results showed that Reken 525 performed good adaptability in most of the trials after 10 years of systematical observation. Advanced trials in the Experimental Farms of CATAS revealed that Reken 525 grew fast with annual stem increment 8.23 cm, which leading this clone to exceed cutting standard for 1.5 year earlier than normal clones; the tappability reached 58.79% in its first cutting year and its annual dry rubber yield was 1.62 kg; its cold tolerance was 1.44 grade, which was equivalent with the control of RRIM600 and better than PR107. It had both middle resistance to powdery mildew disease and rubber tree anthracnose. Meanwhile it had better tolerance to wind injury and TPD. Reken 525 also performed fine adaptability in other planting trials. Accordingly, this clone could be recommended to enlarge its planting region in Hainan, Guangdong and Yunnan with middle wind and cold injury climatic type .关键词
