摘  要：
采用全株调查统计法,对种质圃12个油棕新品种多年来大田抗逆性表现进行了调查与分析。结果表明:连续9个月的干旱在一定程度上影响了油棕的生长、开花、结实与产量,但无植株因干旱死亡,其中品种RYL7和RYL3表现最好;中心风力达11级的强台风后,64%以上植株的叶片受损,但断折叶片仅占树体总叶片数的2.9%～8.2%,无折干和倒伏植株;受持续32d低温冷害,期间花序、初果、小果几乎全部受冻害死亡,受冷害叶片数占植株所有叶片数的3.5%～17.4%,但无植株死亡,当年油棕减产约20%。冷害后所有植株都正常开花、结实;几乎无明显病虫害,多年来没有喷洒过农药,对环境无污染。

摘  要：
Resistance performance of 12 species oil palm planted in the field was observed and analyzed by the way of statistic whole colony.Drought for continuous 9 months affected to some extents the growth,flowers,fruits and yield of oil palm,but did not result in killing of palm trees.Of the 12 species the species RYL7 and RYL3 performed better.Fronds of more than 64% palm trees were injured by strong typhoons with more than force 11 at the Beaufort scale,but only 2.9%～8.2% of fronds were broken off,without stem snapping or lodging.Inflorescence,early fruit and small fruit were all dead when suffering low temperature for continuous 32 days,and 3.5%～17.4% of the fronds suffered cold injury.However,no palm tree died due to cold injury,and the yield decreased by 20% in the same year.All oil palm trees restarted flowering and fruiting naturally after the cold attack.There was nearly no evident attack by diseases and insect pests.The palm trees have not been applied with any agrochemicals,and are environment-friendly.
