Demand for Light and Temperature of Medium Syringa Clove Seed Germination The medium-sized clove, also known as the dew ball flower, is an evergreen shrub of the Rubiaceae family and is 2 to 4 meters in height. The medium-sized clove grows in Dali, Yunnan, and Yishui, etc. in Yunnan, and is in the thickets of 1200-2600 m above sea level. Guangxi also has distribution. The medium-sized clove is the top cyme, the inflorescence is dense and luxuriant, the flower is colorful and fragrant, the plant type is beautiful, and the branches and leaves are luxuriant. It is an excellent ornamental plant and should be arranged in the courtyard or the flower bed. Its roots, flowers, and fruits can be used as medicines to cure diseases such as whooping cough, chronic bronchitis, tuberculosis, rheumatic pain, and migraine headaches. External use can cure poisonous snake bites. Seed germination requires a certain amount of light and temperature requirements, of course, there are other requirements such as humidity, seed quality. By finding some information, we have obtained special requirements for the temperature and illuminance of medium-sized clove seeds. Here we come to a specific analysis. We provide parameters such as germination time and germination potential by providing different temperatures and illuminance, and then recording the number of related germinations. Finally, we obtained: at a constant temperature of 20°C, the germination rates of medium-sized clove seeds were 96% and 0%, respectively, under light and dark conditions; under constant temperature at 25°C, the seeds of medium clove seed were germinated under light and dark conditions. The rates were 100% and 92%, respectively; while at 30°C, the germination rates of medium-sized clove seeds were 90% and 28%, respectively, under light and dark conditions. The difference between light and darkness is significant. The illuminance can be recorded by temperature illuminance recorder and adjusted in time. Under light conditions, the seeds of medium-sized C. syringae have higher germination power and germination rate, and germinate neatly, and the germination of medium-sized C. syringae seeds is darker than that of the early stage. The time required for complete seed germination is shorter; while in the dark Under the condition, the germination potential and germination rate of the medium-sized C. syringae seeds are all lower, the germination is not neat, and the germination period of the seeds is delayed, which takes a long time to complete germination of the seeds. It was shown that light had a significant effect on the germination of medium-sized clove seeds. In addition, the effect of temperature on seed germination was as follows: Temperature had a significant effect on the germination rate, germination potential and germination rate of medium-sized clove seed. The test results showed that the optimum temperature for the germination of medium-sized clove seeds was 25°C. At 25°C, both the seed germination potential and the final germination rate reached the highest values. Temperature control requires the temperature logging function of the temperature and humidity self-monitor. At this temperature, the seeds germinated 12 days later. At 16 days, the germination rate reached the highest value (100%), germination was neat, and the time required for complete germination was the shortest. From the data, it can be seen that with 25°C as the boundary, the germination rate of the medium-sized clove seeds decreased significantly with increasing or decreasing temperature. At 20°C, the seeds began to germinate within 14 days. At 26 days, the seed germination rate reached 96%, but the germination was irregular and the germination time was longer. At 30°C, the seed was also 12 days. Germination begins, but the final germination rate of seeds is only 90%. The self-reporting thermometer and hygrometer always runs through the whole process of the experiment. The self-reporting thermometer and hygrometer can be used to know the temperature of the environment in time and make adjustments. 3 In 1 Milk Frother,Stainless Steel Milk Steamer,Automatic Milk Steamer Machine,Milk Warmer Heshan Zilong Home Appliance Technology CO.Ltd , https://www.techonelfoodmixer.com
