Effects of Different Light Intensities on Vegetative Growth,Phenotypic Characteristics and Ornamental Value of Passiflora suberosa Linnaeus
摘要
Abstract
To explore the adaptability and ornamental value of Passiflora suberosa Linnaeus under different light intensities,the growth dynamics of the main vine,leaves,lateral vines,and other vegetative parts were dynamically tracked under six different light intensities and the related phenotypic characteristics and ornamental value were analyzed.The results revealed that the growth rate,lateral vine length,internode length,leaf length,leaf width,overall growth,and ornamental properties of the main vine and leaves of Passiflora suberosa Linnaeus were significantly greater than those of the other treatments under a daily light intensity of 6 400 1x(T2).The above indicators ranked second,and the indices of lateral branch differentiation speed,villus density,and leaf thickness ranked first under the full sunshine light intensity of 25 400 1x(T1).All the measure-ment indices ranked third under the light intensity of 1 600 1x(T3).The differentiation and growth of Passiflora suberosa Linnaeus tended to stop at light intensities of 400 1x(T4)and 100 1x(T5).The light intensity of 50 1x(T6)and below was the lethal light intensity range of Passiflora suberosa Linnaeus.关键词
