中国菟丝子(Cuscuta chinensis R.Br.)寄主范围很广,但大多侵染双子叶植物,我们于1991年系统地观察到中国菟丝子寄生小麦的情况。 据1991年3月下旬-4月上旬观察,中国菟丝子在小麦行间成片发生,在下水头密布一层淡黄色的嫩茎,高约5-7厘米,有的还未缠绕上寄主,有的已与杂草旋花草、苦苦菜等建立了寄生关系。4月上旬小麦处于拔节期,菟丝子大多在小麦离地面1厘米左右的部位缠绕寄主茎部,也有的缠绕叶片。 Cuscuta chinensis R.Br. hosts a wide range of hosts, but mostly infects dicotyledons. In 1991, we systematically observed the situation of parasitized wheat in China. According to the observation conducted in late March-early April 1991 in early March 1991, Chinese dodders occurred in the middle of the wheat line, with tender yellow stems about 5 to 7 cm high, some of which were not yet entwined with the host. There were Has been with weeds convolvulus, bitter vegetables and other parasitic relationships established. In early April, wheat was in jointing stage. Most of the dodders were wrapped around the host stems about 1 cm away from the ground and some were twining leaves.
