| 摘 要： | 为了比较油棕新品种RYL31—40 10个油棕新品种的抗寒性,在经历了2012年冬季低温寒害之后,于2013年4月对广东省江门市油棕抗寒种植前哨点的油棕试种基地进行调查,测定各油棕新品种的寒害指数。参考《油棕品种区域适应性试种观测技术规范》中寒害调查方法,将所调查的油棕进行分级,然后根据权数计算寒害指数。结果表明,RYL38和RYL32的寒害指数较大,分别为0.286、0.270,RYL40、RYL31和RYL39的寒害指数相对较小,分别为0.157,0.177和0.183。以寒害指数作为评价油棕新品种抗寒性的指标,结果得出10个不同新品种油棕在江门地区能够顺利过冬,其中RYL40、RYL31和RYL39的抗寒性相对较强。

| Abstract: | After the cold chilling in 2012, in order to compare the cold resistance of Elaeis guineensis Jacg new varieties including RYL31-40, Elaeis guineensis Jacg planting base of Jiangmen in Guangdong Province was investigated in April, 2013, and then chilling injury index of Elaeis guineensis Jaeg was determined. Referring to regional the adaptive observing technical specifications of Elaeis guineensis Jacg varieties, the investigated oil palm was graded, and the chilling injury index was calculated according the weight. The results showed that： the chilling injury index of RYL38 and RYL32 were 0.286 and 0.270, respectively, they were larger than the other varieties. While, the value of RYL40, RYL31 and RYL39 were smaller relatively, they were 0.157, 0.177 and 0.183. The results indicated that with chilling injury index as the evaluation of Elaeis guineensis Jacg cold resistance, Elaeis guineensis Jacg could withstand winter, and RYL40, RYL31 and RYL39 showed stronger cold resistance than the other varieties. |
