详细研究了新疆农田寄生杂草菟丝子的种子外部形态特征和种胚形态,对新疆农田主要的菟丝子属植物:苜蓿菟丝子(Cuscuta approximata Bab.)、田野菟丝子(Cuscuta campestris Yuncker)、欧洲菟丝子(Cuscuta europaea Linn.)、亚麻菟丝子(Cuscuta empilinum Weihe)、中国菟丝子(Cuscuta chinensis Lam.)、单柱菟丝子(Cuscuta monogyna Vahl.)、杯花菟丝子(Cuscuta cupulata Engelm)及南方菟丝子(Cuscuta australis R.Br.)共8种菟丝子的种子,分别进行外部形态、种胚形状及结构的描述和绘图,编制分种检索表,为新疆菟丝子的种子检疫及鉴定提供鉴别依据。
In this paper, the morphological characteristics and embryo morphology of the seeds of parasitized weed dodder in Xinjiang were studied in detail. The main dusarium species in Xinjiang were Cuscuta approximata Bab., Cuscuta campestris Yuncker, Cuscuta europaea Linn.), Cuscuta empilinum Weihe, Cuscuta chinensis Lam., Cuscuta monogyna Vahl., Cuscuta cupulata Engelm and Cuscuta australis R. Br. A total of 8 kinds of seeds of dodder, respectively, the external morphology, embryo shape and structure of the description and mapping, the preparation of the seeding search table for the Xinjiang Dodder seed quarantine and identification to provide identification.
