Mangosteen trees grow in mountain jungles. Mangji persimmon (scientific name: Garcinia mangostana? L.), commonly known as mangosteen, or mangosteen, mangosteen, upside down. Small trees, 12-2 meters high, with many and dense branches, alternate and opposite, and branchlets with obvious longitudinal ribs. Leaf blade is thick leathery, glossy, oval or elliptic-oblong, with short tapering tip and wide wedge-shaped or nearly round base.

Male flowers 2-9 are clustered at the top of branches with short pedicels; Female flowers are solitary or paired, inserted at the top of branches, slightly larger than male flowers; Ovary 5-8-loculed, few styles, stigma 5-6 parted. The fruit is purplish red when ripe, with yellowish brown patches, smooth, with 4-5 seeds, and the aril is juicy and white. The flowering period is from September to October, and the fruiting period is from November to December.

Extended data

The drainage conditions are good, and Mangji persimmon needs more water when it grows rapidly. The annual rainfall of 13-25mm in tropical areas can meet its vigorous growth. The uniformity of rainfall distribution during the year will also affect the growth rate of mangosteen. Generally, the uniform rainfall distribution is more conducive to the rapid growth of Mangji persimmon.

Mangji persimmon is a typical tropical rain forest fruit tree, which can grow vigorously at 25-35℃ and 8% relative humidity, and the temperature range of 2-25℃ can also meet the basic requirements of mangosteen growth. However, when the temperature drops below 2℃, the growth of mangosteen will be obviously inhibited; When the temperature is lower than 5℃ or higher than 4℃ for a long time, mangosteen plants will die.

The early growth of Mangji persimmon needs a weak light environment, and the shading degree of 4%-75% is the most suitable for the growth of Mangji persimmon. Under direct light, mangosteen leaves, especially newly-pumped leaves, are easily burned by strong light.

The life span of Mangji persimmon is as long as 7 years, but it grows slowly, and it takes seven or eight years from cultivation to fruiting. The fruit ripens in October-December, and the yield is higher in November-December.
