Classification of tomatoes

There are so many kinds of tomatoes and most people plant ordinary tomatoes now. According to the growth habit of plants, ordinary tomatoes can be divided into two categories, indeterminate growth type and determinate growth type.


Indeterminate growth type: As long as the environmental conditions are appropriate, the main stem can grow up all the time. As for this type, the apical bud is leaf bud, the first inflorescence is higher and it's usually above the ninth leaf, the interval of inflorescences is about 3 leaves which is more than the other type. As a result, indeterminate kind of tomatoes are often late-maturing.

Determinate growth type:Which is also called the cap type. After two to six inflorescences grow from the main stem, growing point turns into inflorescence and stops growing up. It begins to depend on the auxiliary buds at the bottom of leaves to produce new branches. It will stop growing up again when there are two to six inflorescences in the new branch. The process of producing new branches from the auxiliary buds repeats and repeats. As a result, determinate kind of tomatoes are often short and small and they are early middle maturing. Normally, there is a inflorescence every one to two leaves. Among them, some varieties cap after two to three inflorescences occur which is called low cap type while some other varieties cap after four to six inflorescences occur, they are known as high cap type.
