Abstract:
To study the photosynthetic physiological characteristics of Cultivars Prunus Humilis bge. in the region of shandong, analyze on the relationship between the quality of seeds and photosynthesis, In order to formulate reasonable cultivation measures and improve the yield quality of seed production. LI-6400 portable photosynthesis apparatus was used to determine light response curve, diurnal change of photosynthetic parameters of Huadong 1 and Huadong 2. Using vernier caliper and electronic balance to measure the quality data of two varieties of eucalypis, the quality difference was analyzed. Two kinds of Prunus Humilis bge, cultivating in Shandong, had higher photosynthetic rate and higher light saturation point, and the photosynthetic rate were "unimodal" type curve. The change of the two peaks all appeared at11: 00, and had no obvious "lunch break" phenomenon. The photosynthetic rate, the utilization of strong and weak light, and the efficiency of absorption and conversion of light energy of Huadong 2, were all higher than that of Huadong 1, which had better quality. The quality of seed of Prunus Humilis bge is related to its photosynthetic capacity. When planting Prunus Humilis bge., we should formulate reasonable cultivation measures according to its features such as photosynthesis, transpiration, water use efficiency.
