A Detailed Explanation of the Growth Characteristics of Sweet Persimmon Seedlings and Persimmon Cultivation Techniques

What are the growth characteristics of sweet persimmons? Do you know? Would you like to learn about them? Let's take a look together.

1. Fairly strict selectivity for rootstock:Based on the rootstocks commonly used in Taiwan, China, Jiro has better compatibility, Fuyu is poorer, and the Goshо series is even worse, with incompatibility continuing to appear about three years after grafting, leading to death.

2. Sweet persimmons require a certain air temperature during the growth period for astringency to be fully removed:Taking Fuyu as an example, during the growth period from bud break to leaf fall, the average temperature should be above 17°C. During the fruit development period, because metabolism is vigorous, the average temperature should be between 18~19°C. During the period when fruit enlargement stagnates, it should be 21~23°C. Temperatures that are too high or too low are both unfavorable for fruit enlargement.

3. Biennial bearing tendency:The period from flowering to flower bud differentiation in sweet persimmons is relatively short. Usually, flower bud differentiation begins after physiological fruit drop is complete, and this is exactly when nutrient consumption is greatest. In years with many fruits, the tree's nutrients are insufficient to supply flower bud differentiation for the following year, so the number of flowers the next year is low. If there is no proper regulation in years with too many fruits, the fruit load will inevitably affect the following year's fruiting, forming the phenomenon of biennial bearing.

4. Much physiological fruit drop:Fruit drop before June is when the calyx and fruit fall together, called early fruit drop. Fruit drop after June is when the sepals remain on the tree, called late fruit drop.
