What are the methods for germinating蜡梅 (Chimonanthus praecox) seeds?
Today's focus is on introducing the methods for germinating蜡梅 seeds and the easy-to-learn germination techniques for green plants and flowers, let's take a look together!
Different types of flowers have different seed coat structures and physiological mechanisms, which result in varying germination times. For example, as long as seeds of 一串红 (Chinese red), 翠菊 (China aster), and 凤仙花 (Indian pink) are sown at the right time, they can quickly sprout. However, some flowers require several months or even years to germinate, so artificial germination must be carried out to break seed dormancy. The following three methods are commonly used:
One, Variable Temperature Method: Some flower seeds, such as 流苏 (Flos chionanthi), 荚 (fruit pod), 牡丹 (peony), and 芍药 (Chinese peony), have the habit of double dormancy in the radicle and plumule. That is, their radicle (the part of the seed embryo that develops into roots) needs to go through a high-temperature stage of 25°C-30°C for 1 to 2 months or even longer to break dormancy, while the plumule needs to be in a temperature range of 3°C-5°C for 1 to 3 months to break dormancy. For these seeds, they must be mixed with moist sand before sowing, undergo a certain period of high temperature, and then transferred to low temperature. After the variable temperature treatment, spring sowing can lead to quick germination. However, it is crucial to ensure the duration of the high and low temperature periods during the treatment, otherwise the seeds may still fail to germinate after sowing.
Two, Water Immersion Method: For seeds with short dormancy periods and easy germination, such as 紫荆 (redbud), 珍珠梅 (oakleaf hydrangea), and 锦带花 (kerria), soaking the seeds in warm water at 40°C-60°C for 1 to 2 days can facilitate direct sowing. For seeds like 火炬树 (torchwood), immersing them in 90°C water and allowing them to cool naturally for 24 hours softens the gelatinous and waxy seed coats, facilitating water absorption and germination. However, when using the water immersion method, it is important to change the water frequently, and the duration of high water temperature above 60°C should not exceed half an hour. Then, the water temperature should be reduced to below 40°C, otherwise the seed embryo may die.
Three, Low Temperature Method: Some flower seeds, such as 刺梨 (Rosaceous fruit), 蜡梅 (Chimonanthus praecox), 连翘 (forsythia), 丁香 (lilac), and some herbaceous flowers sown in autumn, need to undergo a certain period of low temperature (0°C-10°C) treatment to break the dormancy of the seed embryo and germinate. The method is to mix the seeds with sand at 60% humidity (the sand should form a ball when squeezed and disperse when released), then put them in a plastic bag, seal the opening, place the bag in a flowerpot, and bury the pot in the ground at a depth of 40 to 60 centimeters. Alternatively, the seeds can be placed in a refrigerator at 3°C-5°C for 60 to 90 days, then sown in spring. Or, they can be sown in the open ground in autumn, allowing the seeds to experience natural low temperatures over the winter and germinate the following year.
The above sharing on the methods for germinating蜡梅 seeds and the detailed introduction of the easy-to-learn germination techniques hope to bring some knowledge of flowers to green plant enthusiasts.
