1, the first rapid growth period: from the beginning of flower shedding to the hard core before, lasts 10?15 days, the time in the sunlight greenhouse should be longer. This period of rapid expansion of the fruit, kernels close to the size of corn kernels, kernel volume increased to close to the size of the maturity, but white, not lignified, the seed kernel is mainly endosperm development, liquid jelly-like.

2, sclerotium stage: near normal size kernel began to lignify, this is the fruit in the appearance of the volume of almost stop growing period. During this period, the fruit appearance changes are very small, the development of the mesocarp in the ovary to form the edible part of the almost stopped, while the organization of the nucleus is very active at this time. The kernel shell lignifies, hardness gradually increases, and the color changes from white to brown.

3, the second rapid growth period fruit volume and weight increase rapidly, until the fruit is ripe. This period lasted about 15 days, fruit volume and weight growth accounted for 50% to 70% of the fruit at harvest, the main reason for the growth of the fruit is the increase in cell volume and weight, cell gap increase.

Extended information:

The growth habit of cherry:

Born in the sunny part of mountain slopes or the edge of the ditch, often cultivated, 300-600 meters above sea level. Cherry is a light-loving, temperature-loving, moisture-loving, fertilizer-loving fruit trees, suitable for growth in the average annual temperature of 10-12 ℃, annual precipitation of 600-700mm, annual sunshine hours of 2600-2800h or more climatic conditions.

The average daily temperature is higher than 10℃ for 150-200d, and the extreme minimum temperature in winter is not lower than -20℃ can grow well and have normal results. If there is a local frost, the cherry orchard site can be selected in the spring temperature rises slowly, air circulation of the northwest slope. Considering the shallow distribution of cherry root system is easy to wind fall, the garden to be in the section not subject to wind damage is preferable, the soil to loose soil, deep soil layer of sandy loam is preferred.
