Review of Cold Injury on Rubber Plantations in Southeast Yunnan in the Year of 2007 to 2008

In 2009,an investigation was carried out to review the actual loss of natural rubber and its recovery from cold damage in the year of 2007 to 2008.The results showed there was great difference in cold resistance for different clones,and monoclone in some rubber farms seemed more easier to be affected by this disaster.Furthermore,remedial measures weren’t taken in accordance with the Rubber Tree Cultivation Technical Regulations for recovery.It suggests that further study on reducing loss in or after cold injury should be done based on the Regulations.
