Investigation of Cold Resistance and Rubber Production Capacity of Rubber Clone Zhanshi 327-13 |
| |
Abstract: | The production test area was investigated at the Xinshidai farm of Guangdong province to evaluate the cold resistance and rubber production capacity of the rubber tree clone ‘Zhanshi 327-13’. The result showed that the cold injury level of ‘Zhanshi 327-13’ was 2.1 grade in winter-spring of 2007~2008, and the ‘93-114’ has the same cold injury level. Results of yield analysis in 2009~2014 showed that individual plant yeild of ‘Zhanshi 327-13’ is 1.86-3.24 times than ‘93-114’, the dry rubber content is 3.00%higher than ‘93-114’. ‘Zhanshi 327-13’ is a new clone with strong cold resistance and high yield through the comprehensive analysis. |
