摘　　要：小佛肚竹以特形秆作为观赏性状的重要观赏竹之一,但在自然选择条件下,数量少且变异不稳定。通过正交实验的设计方法,讨论了小佛肚竹在不同的密度、光照、外源激素的条件下,其秆型的变异规律。结果表明,通过人工调控可以改变秆型变异率,在30%遮阴条件下,小佛肚竹的秆形变异比例最高,达80.0%;密度模式为45 cm×45 cm时,小佛肚竹的秆形变异比例最高,达93.3%;外源激素GA3处理,小佛肚竹的秆形变异比例最高,达77.8%。The Bambusa ventricosa cv.nana is an important decorative bamboo for the special shape of its stalk.However,under the natural selection condition,the occurence of Bambusa ventricosa cv.nana is rave and the variation is also unstable.Therefore this orthogonal experiment,through the test of the density,the illumination and the plant hormones on Bambusa ventricosa cv.nana,attempted to research the characteristic of its growth as well as the variation rule.The results showed that the best density patterns is 45...
