摘　　要：西番莲属多年生藤本植物,有很高的开发利用价值,且市场前景十分广阔,但传统的种植方式及西番莲品种本身已经不能满足市场需要,因此,西番莲育种及其育种的改良尤为重要。由于西番莲染色体数目少,且未发现有自然的多倍体变异,所以西番莲多倍体育种是可能的。传统的多倍体育种依靠秋水仙素来完成,但秋水仙素存在很大的不足,许多国内外学者在这方面已进行了不少探索,如用除草剂类的Oryzalin取代秋水仙素作为诱导剂来诱导植物多倍体,并取得了一些进展。本研究对Oryzalin在西番莲多倍体育种中的应用进行探索,以期望取得预期的目的。Passiflora edulis belongs perennial liana,it has high value of exploitation and utilization,and the market prospect is very broad. But the traditional way of planting and Passiflora edulis varieties itself cannot meet the needs of the market,the improvement of Passiflora edulis breeding and breeding is particularly important. Passionflower chromosome number is little,and polyploid variation has not been found in nature,so passionflower polyploid breeding is possible. Traditional polyploid breeding relied on colchicine,but there is a big lack of colchicine,and many scholars at home and abroad has made a lot of exploration in this aspect,with a herbicide such as Oryzalin replace colchicine as inducers to induce polyploid plants,and achieved the expected purpose. This paper explored the application of Oryzalin in Passiflora edulis polyploid breeding to expect to achieve purpose.
