In biology and botany, indeterminate growth is growth that is not terminated, in contrast to determinate growth that stops once a genetically predetermined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate.
Tomato and potato cultivars are commonly classified as determinate or indeterminate according to the amount of time that they produce new leaves and flowers. Varieties that produce few leaves and flowers over a shorter period are classed as determinate and those that produce new leaves and flowers for longer are classed as indeterminate.
A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses, such as oat and crabgrass, [a] as well as other plants such as pistachio and mamoncillo.
Determinate inflorescence: Sympodial (cymose) growth. The terminal bud forms a terminal flower and then dies out. Other flowers then grow from lateral buds. Indeterminate and determinate inflorescences are sometimes referred to as open and closed inflorescences respectively. The indeterminate patterning of flowers is derived from determinate ...
Determinate varieties, such as Roma, are ideal for canning and sauces, while indeterminate types, like Cherry or Beefsteak, produce fruit throughout the season. ... Test your soil’s pH, aiming ...
Indeterminate growth – Inflorescence and leaves growing for an indeterminate time, until stopped by other factors such as frost (see also Determinate). Lax – non upright, growth not strictly upright or hangs down from the point of origin. Lithophyte – Growing on rocks Endolithic – growing in crevices of rocks.
Primary growth gives rise to the apical part of many plants. The growth of nitrogen-fixing root nodules on legume plants such as soybean and pea is either determinate or indeterminate. Thus, soybean (or bean and Lotus japonicus) produce determinate nodules (spherical), with a branched vascular system surrounding the central infected zone.
Determinate nodules are found on certain tribes of tropical legume such as those of the genera Glycine (soybean), Phaseolus (common bean), and Vigna. and on some temperate legumes such as Lotus. These determinate nodules lose meristematic activity shortly after initiation, thus growth is due to cell expansion resulting in mature nodules which ...
