Objective:
To study the influence of host species on growth and development and active component content of Thesium chinense.
Method:
Plant morphology and active component content of T. chinense grown with different hosts were measured. The hosts were evaluated by using index-sum method.
Result:
Hosts significantly promoted the growth of T. chinense by increasing height, per plant weight, stem diameter, leaf area, the number of seed and haustorium,and decreased RW/SW ratio compared to without host treatment. Considerable differences existed among the effect of different host species treatments. Synthetical evaluation score of Gnaphlium affine was the highest (37), followed by Imperata cylindrical and Prunella vulgaris (36). It is suggested that they were superior hosts for T. chinense. But the scores of Triticum aestivum (25) and Eremochloa ophiuroides (17) were lower, so they were unsuited hosts for T. chinense.
Conclusion:
Hosts significantly promoted the growth of T. chinense. Considerable differences existed among the growth and development of T. chinense grown with different hosts, as well as active component content. Gnaphlium affine, Imperata cylindrical and Prunella vulgaris were superior hosts for T. chinense. While Triticum aestivum and Eremochloa ophiuroides were unsuited hosts for T. chinense.
