Abstract
In order to verify whether there are relevant substances in Jacaranda mimosifolia that can produce the allelopathy to other plants. We studied the allelopathy of the concentration of 0. 001,0. 025,0. 050 g·m L- 1water extract of the flowers of J. mimosifolia for the seed germination and seedling growth,taking the complete single flowers of J. mimosifolia grown in Wenjiang region as materials,the seeds of Lactuca sativa and Festuca arundinacea as receptor materials,and the water treatment as the control CK. The results were as follows: firstly,the seed germination of F. arundinacea and Lactuca sativa was suppressed by the water extract,especially performance on the germination index,and the comprehensive allelopathies( SE2) were-0. 13 and-0. 27 respectively; secondly,the seedling height of L. sativa was promoted but its root length and root-shoot ratio were suppressed,and the values of SE3,SE4,SE5 were 0. 13,-0. 36,-0. 16,while the root-shoot ratio of Festuca arundinacea were promoted but its seedling height and root length were suppressed,and the values of SE3,SE4,SE5were-0. 12,-0. 08,0. 16 respectively. Meanwhile the MDA contents and root vigor of Lactuca sativa were also suppressed,whose values of SE6 and SE7were-0. 25 and-0. 44,the values of Festuca arundinacea were 0.04 and 0. 34 reversely. Most of all,when the concentration of the water extracts was 0. 025 g·m L- 1,it showed the RI peak and inflection point of some trend in many places,especially the changes in MDA contents and root vigor of receiver plant's leaves. Thus,the experiment proved the existence of allelochemicals in water extract of Jacaranda mimosifolia flowers,Lactuca sativa and Festuca arundinacea,and they had different responses to the allelochemicals,which will provide the relevant theoretical basis to the plant landscape design and maintenance of Jacaranda mimosifolia in the future.
