2、最低.结果表明:大蒜溶液浓度较低的时候,波斯菊和雏菊种子在溶液处理下无明显变化,但是浓度过高会抑制种子萌发。关键词:大蒜鳞茎;分蘖葱头;波斯菊;雏菊;;AbstractAllelopathy is widely exists in natural ecological system, refers to the plant allelopathy of plant (including microbiological) by releasing chemicals into the environment to other plants (incl
3、uding microbiological) as a result of the direct or indirect harmful effects. The definition of RICE showed that allelopathy of chemical substance is released by plants, allelopathy of results is harmful to other plants or microbes. Now, however, research has shown that the ob
4、ject of the allelochemicals role is more than other plants, sometimes even the same plant. The allelopathy includes not only the result of the harmful, also include some mutual promotion effect. Therefore, somebody called allelopathy of plant - based.Allelopathy between plants
5、 is a hot research topic in today's plants. This time, we take the marigold and clovers crops as receptors, passed the test of the seed germination and seedling growth test, the points nie onion liquid and garlic (Allium fistulosumL. Var. Caespitosum Makino) of root system and
6、 aboveground water immersion allelopathy is studied. The results showed that the tiller onion and garlic aboveground liquid water immersion of marigold and clovers allelopathy. When the concentration reaches a certain degree, have a certain role in promoting. But on the contra
7、ry, when the concentration reaches a point also can have certain inhibition. Therefore, to expand the experiment we set a concentration gradient. We hope this research of tillers of onion and garlic liquid concentration for the growth of chrysanthemum and all over the sky star
8、, can contribute strength for chrysanthemum growth subject. K
