Malay apple is a strictly tropical tree and will be damaged by freezing temperatures. [12] It thrives in humid climates with an annual rainfall of 152 cm (60 in) or more. It can grow at a variety of altitudes, from sea level up to 2,740 m (8,990 ft). The tree can grow to 12–18 m (39–59 ft) in height.
The growth cycle of M. sieversii could be divided into several stages from germination to developing fruit bearing trees, and to the death of aged trees. [7] Period I starts from seed germination to the development of vegetative tree parts, and to the first round of fruiting. [7] A typical apple tree reaches age 6 to 8 in this period.
Apple scab is spread through fungus growing in old apple leaves on the ground and spreads during warm spring weather to infect the new year's growth. [ 61 ] Among the most serious disease problems is a bacterial disease called fireblight , and three fungal diseases: Gymnosporangium rust, black spot , [ 62 ] and bitter rot . [ 63 ]

[citation needed] New shoots are dark purple, and leaves range from purplish when new to dark green when mature. In the spring it puts out intensely magenta-rose flowers.

Antonovka apples. Antonovka is a cultivar of vernacular selection, which began to spread from the region of Kursk in Russia during the 19th century. [4] While the fruit-bearing trees have not received a wide degree of recognition outside the former Soviet Union, many nurseries do use Antonovka rootstocks, since they impart a degree of winter-hardiness to the grafted varieties.
