Effects of Light and Temperature on the Germination of Motherwort Seeds Motherwort is a 1a or 2a herbaceous plant of the genus Lamiaceae of Lamiaceae. It is used as a whole herb and has the functions of regulating blood circulation, diuresis and swelling, and has a wide range of clinical applications. The natural regeneration ability of Motherwort is low. In the process of cultivation, there is a phenomenon that the seed germination rate is low, which has a great influence on the product yield. Natural environments such as light and temperature will have a certain influence on the growth of Motherwort. Here we will analyze how temperatures and illuminance affect the growth of Motherwort and its yield. Among them, we control temperature and light by cultivating Motherwort seeds or seedlings in a light incubator, because the light box is a scientific instrument that can be used to set parameters such as set temperature, illumination, and humidity. Effects of light intensity on seed germination of Leonurus: By measuring the seed germination rate, germination potential and germination index of Leonurus radix seed cultured in dark, 32, 40, 50, 60, and 74 μmol·m-2·s-1 light intensity, and The analysis of variance showed that the seed germination rate, germination potential and germination index of Leonurus had no significant differences under different light intensity conditions (F germination rate = 3.480; F germination potential = 0.442; F germination index = 0.620, P> 0.05). Therefore, the following tests were conducted under dark conditions. The effect of temperature on the seed germination of Leonurus sinensis seedlings: The temperature had a great influence on the seed germination of Leonurus, and the analysis of variance showed that the difference between the treatments of germination rate, germination potential, and germination index was extremely significant within the treatment. The data showed that the seed germination rate, germination potential, and germination index were the highest at 30°C, and the seed germination rate was lowest when the germination temperature was 10°C and 45°C. There was no significant difference in germination rate, germination index, and germination power at 10°C, 15°C and 40°C, and there were significant differences among others. The analysis showed that the seed germination temperature was 15~40°C, but it germinated early at 30~35°C, and the germination rate was high. The suitable germination temperature was 30~35°C. Thus, temperature is one of the key factors that restrict the germination of Leonurus seeds, and the high temperature is more suitable for the germination of Leonurus seeds. Hand-held meteorological stations are occasionally used in such experiments, because sometimes it is necessary to measure the temperature, humidity, and carbon dioxide concentration of the environment in time. These parameters will have a certain influence on the growth of motherwort. 27 Caliber Straight Valve,27 Caliber Straight Valve Regulator,Lpg Gas Cylinder 27 Caliber Regulator,Lpg 27 Caliber Valve Regulator Jiangsu Minnuo Group Co., Ltd. , https://www.minnuocm.com
