Meaning of the term "determinant"

First of all, we find out what the determinant variety of tomatoes means. This term is derived from the Latin word "determination", which translates as "limitation, limit". Tomato varieties having such a definition are self-limited in growth. Plants of this variety tie an average of 4-8 brushes and stop their growth.The distinction of the indeterminate is that they have no restriction in growth and they can have an unlimited number of brushes. Because they need to pinch the top.

What does a determinant variety of tomatoes mean?

In plants of this species, the first ovary is formed after the 5-7th leaf, and the next after only 2. The main advantage of these tomatoes is in early harvest and fruit ripening almost simultaneously. In addition, the limited growth of tomatoes significantly reduces the labor costs of plant care. In the middle lane from determinant varieties of tomatoes, a high yield is obtained even when grown in open ground.

Varieties of determinant varieties

This group of plants is divided into four varieties. They differ in their limited growth; moreover, each has its own characteristics.

  1. Semi-determinant. These tomatoes are sometimes confused with indeterminate. Plants stop growing only after they form 10-12 brushes with set fruits, while laying leaves at them occurs every two full-fledged leaves (rarely after three). In this case, the first brush is formed before the 8th or 9th sheet.
  2. Determinant.In tomato varieties, brushes are formed only with an interval of less than 3 leaves. The first inflorescence is formed after the 6-7th leaflet. After the appearance of 5-6 brushes, the growth of tomato ends with a brush.
  3. Super determinant. All varieties are distinguished by precocity. Brushes are laid in 1-2 sheets. Then, after the formation of brushes (4-5 pieces), sprout grows, which completes the growth of the plant inflorescence.
  4. Supersuper determinant. This variety includes super dwarf and super-early varieties. The row formed 2-3 floral brushes, not having gaps from the leaves. Plant growth is completed after 3-4 brushes are formed. Moreover, the first appears after the fifth sheet, and the next can already form through the sheet.
