摘要
本文报道柑桔根线虫在重庆地区的田间消长规律,查明柑桔根线虫在田间发生量以1～3月和10～12月最多,7～9月最少。雌成虫对须根的寄生量周年基本相同。据对7种柑桔砧木抗病性的初步观察证明,枳对柑桔根线虫病抗性最强,枳橙次之,其余砧木(包括柚、红桔、枸头橙、酸橙和香橙)均感病。
The pupulation of citrus root nematode (Tylenchulus semipenetrans Cobb)has been observed in a sweet orange orchard in Chongqing, Sichuan province, The density of larvae in fibrous root during spring or winter was higher than that during summer,but the population of female adults changed a little during different seasons. Among 7 citrus rootstocks, the trafoliate orange (Poncirus trifcliata Raf. ) has high resistance to the nematode disease,and the citranges(P, trifoliata × Citrus sinensis)has moderate resistance, and the others including shaddock, tangering, Goutoucheng (sour orang hybrid) , sour orange and Citrus junos are susceptible.
