Gender differences analysis of apparent traits of Humulus scandens in response to temperature in the vegetative growth stage

Through determination of the vegetative growth duration of individual male and female Humulus scandens, the data of quantitative traits of components(root, stem, leaf), fresh weight, dry weight and biomass allocation, this paper analyzes the impact that temperature has on the growth characteristics of male and female Humulus scandens during their vegetative period under culture conditions with temperature of 15 ℃, 20 ℃, and 25 ℃. The results show that temperature has a significant influence on the vegetative growth duration of Humulus scandens (P0.01). Female plants are more sensitive than male plants to temperature, temperature also significantly affects the data of quantitative traits of components (root, stem, leaf), fresh weight, and dry weight and the same influence can be seen on the constitution and total biomass of the single female and male Humulus scandens in the vegetative growth stage. Material basis for reproductive growth is supported by male and female Humulus scandens, through reducing leaf biomass and increasing root biomass respectively.
