- Abstract
【Objective】 To study the biological characteristics of leaves of red Fuji bud and to provide reference for the selection of superior bud variety.【Method】 In this experiment, three preferred types of red Fuji bud and two types of red Fuji were used as experimental materials to compare leaf characteristics with photosynthetic characteristics and analyze the correlation.【Result】 There was no significant difference in leaf length, leaf width, leaf thickness and leaf area of all materials tested (P<0.05), while the leaf weight and chlorophyll content of N1 and N2 were significantly different from those of the other three. There were also obvious differences in materials; the net photosynthetic rate and stomata conductance of N1 were significantly higher than those of other materials; the daily change of the net photosynthetic rate of the test material was a 'bimodal' curve, showing an obvious photosynthetic 'midday break' phenomenon, but the peaks and troughs appeared at different times; correlation analysis shows that the net photosynthetic rate was extremely positively correlated with stomatal conductance, chlorophyll content, water use efficiency and transpiration rate (P<0.01), and was extremely significant negative correlation with intercellular CO2 between cells (P<0.01).【Conclusion】 The net photosynthetic rate, chlorophyll content, single leaf weight and stomatal conductance of "N1" were significantly higher than those of the other four test materials, showing strong photosynthetic capacity, which can be used as key materials for further seed selection of bud variation.
