BACKGROUND
Ashwagandha (Withania somnifera) is an important medicinal plant in Indian traditional system of medicine and traditionally has been used for several medicinal purposes in the Indian subcontinent.
OBJECTIVE
The present study was aimed at the evaluation of allelopathic effect of hydroalcoholic extract of ashwagandha against germination and radicle growth of Cicer arietinum and Triticum aestivum seeds.
MATERIALS AND METHODS
The extract at different concentrations was incubated in controlled conditions with the surface sterilized seeds of C. arietinum and T. aestivum and observed periodically for seed germination and radicle growth to assess the allelopathic behavior.
RESULTS
The extract mainly at higher concentrations demonstrated promising allelopathic potential by significantly affecting seed germination and radicle elongation of both C. arietinum and T. aestivum in a concentration dependent manner. T. aestivum was found to be more sensitive than C. arietinum.
CONCLUSION
The present study demonstrated remarkable allelopathic potential of ashwagandha against the test seeds. The effect was plausibly due to the alkaloid and withanolide contents of ashwagandha.
背景
印度人参（南非醉茄）是印度传统医学体系中的一种重要药用植物，在印度次大陆传统上已被用于多种药用目的。
目的
本研究旨在评估印度人参水醇提取物对鹰嘴豆和普通小麦种子萌发及胚根生长的化感作用。
材料与方法
将不同浓度的提取物在可控条件下与经表面灭菌的鹰嘴豆和普通小麦种子一起培养，并定期观察种子萌发和胚根生长，以评估化感行为。
结果
提取物主要在较高浓度时表现出有前景的化感潜力，以浓度依赖的方式显著影响鹰嘴豆和普通小麦的种子萌发和胚根伸长。发现普通小麦比鹰嘴豆更敏感。
结论
本研究证明了印度人参对受试种子具有显著的化感潜力。这种作用可能归因于印度人参中的生物碱和睡茄内酯成分。
