摘要
采用野外踏查和样点调查相结合的方法对吉安市南方菟丝子寄主的种类及危害进行了调查,并对寄主组成及寄生关系的利用进行了分析探讨。结果表明:吉安市南方菟丝子寄主种类涉及23科62种植物,以菊科、豆科寄主植物最多,分别为11种(17.74%)和8种(12.90%),并对菊科、豆科、唇形科及旋花科的大部分寄主植物产生较严重的危害。南方菟丝子可寄生香丝草等14种(22.58%)入侵植物,并对大狼把草等5种植物产生严重危害。南方菟丝子寄主植物种类繁多,属于广寄性种类,其对入侵植物的寄生危害性将为防治入侵植物提供重要思路。
The host species and the hazard of Cuscuta australis in Ji’an city were investigated by the methods of combining field survey and sample spot survey,and the host composition and the utilization of the parasitic relation were analyzed and discussed.The results show that there are 62 host species in 23 families for C.australis in Ji’an city,of which the largest are Asteraceae and Leguminosae,with 11 species(17.74%)and 8 species(12.90%),respectively.C.australis has great endanger on most host species in Asteraceae,Leguminosae,Lamiaceae and Convolvulaceae.C.australis can parasitize 14 invasive plants including Conyza bonariensis,with great endanger on 5 species including Bidens frondosa.It can be seen that the host species of C.australis are various,it is a wide parasitic species,and its parasitic harm to invasive plants will provide important ideas for the prevention and control of invasive plants.
