Narrative

Pretreatment of seeds of rootstock before sowing. The seeds of the rootstock will germinate only after the treatment of cold stratification. The stratification method is as following: 1) Stratification time: in late January. 2)Treatment: seeds are soaked in water for twelve hours. After seeds are saturated with water, seeds are mixed with fine sand in the proportion of 1:4-6. The moisture content of sand shall be appropriate when sand can be held together in the hand but with no free water flowing out. The container used for storage can be a wooden box or a chinaware. Cover the sides and bottom inside the container with a layer (approximately two centimeters thick) of moist sand; then place the mixture of seeds and sand inside the container; fill the top of the container with a five centimeter depth of moist sand; at last, seal the top with a layer of white plastic film (0.05 to 0.10 mm thick). The container should be placed at an open and cool place (such as outside the northern sideof the house). The optimum storage temperature is between two to six degrees Celsius. Be sure to check the moisture inside the container occasionally. In spring when temperature rises, the seeds are ready to be sown.
