国家橡胶树种质资源大田鉴定圃2011年“纳沙”台风风害调查

摘要

Typhoon No. 17 ＂Nesat＂ had a severe impact to the growth of rubber trees in Hainan Province after attacking in 2011. A comprehensive investigation was done to find out the anti-wind capacity of the rubber tree in national germplasm resource field identification nursery. Investigation results were that 201Wickham clones were unaffected by wind damage with anti-wind ratio 51.41%; and 520 1981＇IRRDB wild germplasm clones were unaffected by wind damage with anti-wind ratio 30.82%, which indicated that there were a lot of anti-wind rubber tree resource in national germplasm field identification nursery, but some degree of difference between in the germplasm of diverse genetic background. Also found that the windbreaks of Acacia mangium had obvious efficiency within 18 meters around the nursery. This investigation results provided excellent resources for rubber tree anti-wind breeding and theoretical basis of windbreaks scientific planning.%对国家橡胶树种质大田鉴定圃中橡胶树种质资源．在2011年第17号台风“纳沙”登陆海南后的抗风害能力进行全面调查。结果表明：201份橡胶树魏克汉（Wickham）品种未受风害，抗风比例为51．41％；520份1981’IRRDB野生种质未受风害，抗风比例为30．82％。种质资源圃中存在大量抗风的橡胶树资源，但遗传背景不同的种质在抗风能力上具有一定程度的差异。同时发现，大田圃四周的马占相思（Acacia mangium willd.）防风林带在风向辐射18m内防风效能比较明显。
