对海南岛初期引进的油棕进行了亩产量、形态性状和抗寒性变异的鉴定。根据10～15年的原始材料分析,其结果明显地说明,早期引入南滨农场的大叶杜拉型种最好,果穗年产量为每亩800公斤以上。可是,海南岛的日里杜拉种适应性不强,在当地条件下,产量很低。在本院的日里杜拉种中,笔者发现其叶片的寒害程度和果穗败坏有明显的正相关(r=0.935)。经产油组分和其他选择因子的鉴定之后,从南滨和本院选出15株亲本,并估计了这些亲本可能的产量。
Hainan Island early introduction of oil palm per mu yield, morphological traits and cold resistance variation identification. According to the analysis of the raw materials from 10 to 15 years, the results clearly show that the early-stage Dulla species introduced into Nanbin Farm is the best with an annual yield of 800 kilograms per acre or more. However, adaptability is not strong in Rinlidu Island of Hainan Island. Under local conditions, the yield is very low. In our hospital, the author found that there was a clear positive correlation between the degree of chilling injury and ear rot (r = 0.935). After identification of oil-producing components and other selection factors, 15 parents were selected from Nanbin and our hospital and the possible yield of these parents was estimated.
