摘要
IAN873是从国外引进的一个速生高产抗性较强的橡胶树优良品种。在广东省高州市3个农场的生比区和南亚所高级系比区,开割9割年内的平均株产干胶产量和每公顷干胶产量均显著高于GT1(对照种),增产幅度均达30%以上;干胶含量与GT1相当,胶乳和生胶性能好;开割前后的茎围生长和抗寒性均显著强于GT1,抗白粉病和炭疽病能力也强于GT1;抗风性与GT1相当。适宜在轻风轻寒区、轻风中寒区(北坡除外)作大规模推广种植。
Absract IAN873is a fast-growing,high-yielding and highly resistant rubber clone.Production trials at the three state farms in Gaozhou,Guangdong and advanced clone trials at the South Subtropical Crops Research Institute showed that the dry rubber yields per tree and per hectare of IAN873in the first nine tapping years were obviously higher than those of the check clone GT1,both the increment of the dry rubber yield per tree and the increment of the dry rubber yield per hectare being more than30%.Its dry rubber content was similar to that of the check clone GT1.The girth growth and the cold resistance of the IAN873before and after tapping were significantly better than those of the check clone GT1,and its powdery mildew and anthracnose resistances were stronger.Its wind resistance was similar to that of the check clone GT1.It is fit for planting on large scale in mild-wind and mild-cold areas and in mild-wind and medium-cold areas(except in the northward slopes).
