4. Price
Nina Queen has not yet entered the mainstream grape production industry in China. It is planted on a small scale in Honghe and Binchuan, Yunnan, with an average purchase price of 50-60 yuan per jin.
5. Characteristics
However, its flowering bud stage has a relatively weak tree vigor. As a variety with a very high flowering rate, Nina Queen indeed has a somewhat weak growth momentum, which is a characteristic of the variety. It is prone to fruit splitting in the later stage, and many growers, in their excessive pursuit of large fruits, easily encounter fruit splitting in case of sudden rainfall or high-temperature weather.
Difficult to change color during the maturation stage. Currently, the feedback from plantations growing Nina Queen is that it is indeed difficult, which should be due to the variety's characteristics. In areas with higher temperatures, the difficulty in changing color is even more pronounced.
