摘要(Abstract):

[Objective] To study the morphology characteristics of the individual growth of Silybum marianum (L.) Gaertn. [Method] Seedling materials were cultivated in laboratory; young plants were planted in open filed. The external morphology and growth rhythm of S. marianum were observed and recorded. Then, hand-held slicing method and temporary slice method were used to observe the structures of fresh leaves and roots. Morphological characteristics of seedling, roots, stems and leaves were researched by conventional paraffin section technique. [Result] As for the seed germination method, cotyledon was epigeal and shallow sowing should be adopted. Structure of nutritive organs of seedlings and plants was characterized by typical herbaceous dicotyledon structure. Synantherous stamen was a little shorter than the corolla lobe. And the growth period was 125-140 d. [Conclusion] The morphology characteristics of the individual growth of S. marianum were researched, which provided references for the standard cultivation of S. marianum.
