Fixed growth involves the elongation of preformed stem units after a rest period. Usually, determinate tomatoes don’t need any pruning at all. Growth of both types is similar during the vegetative growth phase until flowering. On the most basic level, that really just means that one type of plant grows and grows without end and the other experiences growth for a … The primary shoot of a young tomato plant produces 5 to 10 leaves, then produces a flower cluster. Plants are capable of indeterminate growth because they have perpetually embryonic tissues called meristems. Determinates stop growing when fruit sets on the top bud. Determinates produce fruit first, usually in a two- to three-week period, while indeterminate varieties will produce fruit after a longer period. Indeterminate plants continue to develop leaves on the main stem and branches throughout flowering. Indeterminate tomato plants have a more vine type of structure and can grow over ten feet tall. Once soybeans begin to flower, indeterminate and determinate plants differ dramatically in stem growth habit. Determinate tomatoes, or "bush" tomatoes, are varieties that grow to a compact height (generally 3 - 4'). What's the difference between "indeterminate" and "determinate" tomatoes? Both determinate and indeterminate tomato varieties have their pluses and minuses. Determinate growth: a type of growth characteristic of most animals and some plant organs, in which the growth stopes after a certain size it reaches. All the tomatoes from the plant ripen at approximately the same time (usually over period of 1- 2 weeks). How determinate tomatoes and indeterminate tomatoes differ. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate. The terms determinate and indeterminate are descriptions of how a tomato plant grows. In indeterminate cultivars, the shoot continues to grow upward and flower clusters appear to develop to the side of a main shoot or main stem. Shoots may be formed by fixed (determinate) growth, free (indeterminate) growth, or a combination of both. Resistant Varieties for both Determinate and Indeterminate Tomatoes include some of the following: A Alternia (early blight) stem canker;, " VFN " indicates the variety is resistant to Verticillium wilt, Fusarium wilt (generally both races of the Fusarium wilt fungus), and root-knot nematodes. But mild pruning of lower older leaves, dry leaves, or any diseased leaves of plants can perform better. They need pruning in different stages of plant growth. If you want a thick tomato for making sauces, you are better off with a paste tomato, which tends to be determinate. Typically, indeterminate tomatoes need regular pruning for better production. Examples: leaves, thorns, flowers Determinate tomato plants are small and bushy, typically no more than four to five feet tall. So what is the difference between a determinate and indeterminate tomato plant? The difference between determinate and indeterminate ultimately boils down to the length of harvest and the time of harvest. In biology and botany, indeterminate growth is growth that is not terminated in contrast to determinate growth that stops once a genetically pre-determined structure has completely formed. Growth habits: determinate vs. indeterminate. It really depends on what you are going to be using the tomatoes for and how long your growing season is. Each flower cluster is referred to as a 'hand'.
