As a plant with high photosynthetic efficiency, the chlorophyll content has become an important physiological index of pumpkin production process. The relationship between the chlorophyll content and the net photosynthesis rate has been studied, but research on pumpkin chlorophyll is relatively rare. The chlorophyll content of pumpkin leaves was systematically studied. The relationship between chlorophyll content and photosynthetic rate was also observed. The rules were found to provide theoretical basis for future research and cultivation. Chlorophyll content was determined using a chlorophyll detector.
The photosynthetic apparatus was used to determine the net photosynthetic rate of four pumpkins. During the measurement, the vent pipe was kept away from the human body for 3m, and a buffer device was used to keep the airflow stable. The measurement period of the net photosynthetic rate is the same as the measurement period of the chlorophyll content, and it is measured every 2 hours from 8:00 to 18:00 for each measurement, and the average value of daily measurements is taken.
Chlorophyll per unit area increases, but due to the increase in leaf thickness, the mass per unit area of ​​the leaf increases, and the area of ​​perforation decreases. The water content of the leaves is easily increased or decreased by the influence of cultivation factors such as temperature and light intensity, resulting in unstable data, which is difficult to avoid during cultivation. The net photosynthetic rate is the number of grams of organic matter left behind after the organic matter produced by the plant minus the consumed organic matter. The main organs of photosynthesis in most plants are leaves, and chlorophyll is the main pigment for photosynthesis of plants, so the level of chlorophyll content is closely related to the net photosynthetic rate of plants. The chlorophyll content and net photosynthetic rate of the four varieties of pumpkin leaves were compared below to observe their correlation.
Analysis of the chlorophyll content of pumpkins at different growing stages by chlorophyll detector showed that the chlorophyll content gradually increased during the vegetative period of the pumpkin (the seedling stage and the ranch stage); the chlorophyll contents of the offspring and the parents were compared. The similarity between the offspring and maternal changes is similar to that of the chloroplasts, which again confirms that the heredity of the chloroplasts follows the cytoplasmic inheritance law; the comparison of the change laws of the chlorophyll content and the changes of the net photosynthetic rate of all varieties can be seen that the chlorophyll content is consistent under the same environmental conditions. The change in net photosynthetic rate is positively correlated.
