Allelopathic Effects of Sunflower (Helianthus annus L.) against Luffa cylindrica (L.) Roem
Journal Title: GU Journal of Phytosciences - Year 2021, Vol 1, Issue 2
Abstract
The Sunflower (Helianthus annus L.) has been considered for allelopathic plant and it has potential properties against different weeds and crop plants. The sunflowers usually release the allelochemicals to influence the growth and germination of different plants and crops. In present study, screenhouse and lab-based experiments were carried out to explore the allelopathic effect of H. annus against test crop Luffa cylindrica (L.) Roem. The petri-plate method was applied in lab by the application of whole plant extract of Sunflower with different concentrations (4, 8 and 10%). The seedling germination of test crop L. cylindrica was evaluated in petri-plate experiment and the control seedling was treated with distilled water in lab-based conditions. However, clay pot method was applied in greenhouse conditions. The soil was amended by whole plant powder extract with concentration of 4, 8, and 12g was inoculated in soil of clay pot and control plant were filled without soil treatment inoculation. The growth parameters like percent germination, germination index, radicle and plumule elongation, seedlings growth, fresh and dry weights and chlorophyll contents of test crop L. cylindrica were studied. During this research study, the plumule lengths of L. cylindrica were much more affected by the extract concentration as compared to control. Powder also contained phytotoxic compounds that caused remarkable reduction in plant heights and chlorophyll contents of test species. In addition, it can be concluded from this research observed the allelopathic effects of sunflower extract and powder showed inhibitory effects on different growth parameters of L. cylindrical.
