The seasonal changes in photosynthesis of the genus Prunus are very different due to different species and ecology. Pn is caused by the combined effects of leaf growth conditions and environmental factors. It has obvious seasonal changes. Seasonal changes may be due to incomplete differentiation of apricot leaves and mesophyll tissues. The reduction of chlorophyll content and chloroplast function is not perfect. The photosynthetic apparatus was used to reduce the intensity of photosynthesis measured by it, and the respiration was consumed.
With the development of the leaf, the photosynthetic rate gradually increased. When the leaves were fully developed, the chlorophyll content also reached a higher level, and the photosynthetic rate was the strongest. After a certain period of time, as the leaf senescence, the photosynthetic rate was found by the photosynthetic apparatus. It gradually decreased again. There are few studies on the seasonal changes of photosynthesis in Pleurotus, but when Yin Li studied the photosynthetic characteristics of Prunus persica, it was found that the Pn of P. oleifera leaves in different months was obviously different, and the variation curve showed a bimodal pattern.
From the beginning of leaf development, Pn increased from negative to positive. Afterwards, with the increase of solar radiation, excessive photosynthetically active radiation and temperature restrained the increase of Pn, causing Pn to decrease. The photosynthesis instrument showed that there was a trough in July. However, it rose again in September because of the weakening of solar radiation, the release of light suppression, the reduction of solar radiation in October, and the rapid decrease in photosynthetically active radiation, and the rapid decline in atmospheric temperature forces Pn to decline.
Therefore, most people think that the seasonal variation curve of photosynthesis in the genus Bryonia is also bimodal. The photosynthetic rate analysis of the genus Apricot by the photosynthesis instrument shows that most of the plant leaves will have similar and regular changes. Affected by the environment and itself, the photosynthetic rate of plants of different cultivars will not be the same and their growth will be different. The impact is also significant.
