Once soybeans begin to flower, indeterminate and determinate plants differ dramatically in stem growth habit. Both determinate and indeterminate tomato varieties have their pluses and minuses. It really depends on what you are going to be using the tomatoes for and how long your growing season is. But mild pruning of lower older leaves, dry leaves, or any diseased leaves of plants can perform better. 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. 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. Growth of both types is similar during the vegetative growth phase until flowering. All the tomatoes from the plant ripen at approximately the same time (usually over period of 1- 2 weeks). Plants are capable of indeterminate growth because they have perpetually embryonic tissues called meristems. 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. How determinate tomatoes and indeterminate tomatoes differ. What's the difference between "indeterminate" and "determinate" tomatoes? Growth habits: determinate vs. indeterminate. Each flower cluster is referred to as a 'hand'. Determinate tomato plants are small and bushy, typically no more than four to five feet tall. Fixed growth involves the elongation of preformed stem units after a rest period. 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. Indeterminate plants continue to develop leaves on the main stem and branches throughout flowering. Determinates produce fruit first, usually in a two- to three-week period, while indeterminate varieties will produce fruit after a longer period. Indeterminate tomato plants have a more vine type of structure and can grow over ten feet tall. The difference between determinate and indeterminate ultimately boils down to the length of harvest and the time of harvest. Shoots may be formed by fixed (determinate) growth, free (indeterminate) growth, or a combination of both. 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 … So what is the difference between a determinate and indeterminate tomato plant? Determinates stop growing when fruit sets on the top bud. The primary shoot of a young tomato plant produces 5 to 10 leaves, then produces a flower cluster. 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. Usually, determinate tomatoes don’t need any pruning at all. Determinate tomatoes, or "bush" tomatoes, are varieties that grow to a compact height (generally 3 - 4').
