Another special advantage of the variety is better salt-tolerating capacity compared to other varieties of star apple. During the two fierce salt intrusions in 2016 and 2020, with the same watering and caring conditions, other star apple trees in many orchards in Nhon My died while the trees of this variety stilled developed as normally. According to Thang, salt water sometimes leaked into ditches in the orchard with salinity of 3‰ but his orchard showed no sign of damage due to salt intrusions.
In terms of morphological characteristics, in comparison with the purple star apple variety is widely cultivated in Ke Sach district, the new variety has bigger leaves with more wrinkles, and the underside of the leaves and flowers has darker yellow-brown color.
The fruit quality is also outstanding. When open a star apple, there is no latex, the seeds are completely peeled, the skin is thin, and the flesh is thick and delicious.
With these unique characteristics, the new star apple variety is warmly welcomed in the domestic market. The fruits of this variety are sold well at prices 1.5-2 times higher than other varieties of purple star apple. Many exporting enterprises took field trips to the orchard to take samples for analysis, saying that the fruits meet requirements from importing countries in terms of size, appearance and quality
However, the cultivation area of this variety is only 3.5 ha of which two hectares of trees is bearing fruit when the trees are at the age 6 and 7. The remaining 1 hectare is just one-year old trees.
