Cuscuta chinensis is parasitic on dry land plants.
Cuscuta chinensis belongs to Convolvulaceae and is an annual parasitic herb. However, it lacks the structure of roots and leaves and is light yellow and filiform. It is a physiological parasitic plant, with no chloroplast in its cells, and generally adheres to dry land plants such as hibiscus, rhododendron, rose and osmanthus.
Cuscuta chinensis was colorless and filamentous at first, and attached to soil particles. If it touches the host, it will wrap around it, and at the same time form root suction and enter the internal tissue of the host. Some cells differentiate into ducts and sieve tubes, which combine with the host's ducts and sieve tubes to absorb nutrients.
At the initial stage of connection with the host, its tussah silk will die, and then the rhizome will continue to extend, become a suction root again, and continue to spread around. When it matures, the host will be covered with dodder, which will make the host plant grow badly and even lead to the direct death of the host.
Generally, Cuscuta chinensis blooms in September, and its seeds mature in June 5438+ 10. After the seeds fall into the soil, they will sleep in winter, or wait until February-March of the following year, and then continue to germinate, waiting for the opportunity to find a host. If there is no host, they will live for about 1 month and a half.
