What is the difference between determinate and indeterminate growth in plants?
Determinate growth in plants refers to growth that is limited by genetic factors, typically resulting in a specific size or shape. Indeterminate growth, on the other hand, refers to growth that continues throughout the life of the plant, typically resulting in larger or more complex structures. In agriculture, determinate varieties are often preferred for crops such as tomatoes or beans, while indeterminate varieties are preferred for crops such as vine crops or fruit trees.
Determinate plants- Plant growth in which the main stem ends in an inflorescence/Flower.
Indeterminate plants- Growth is not terminated by reproductive growth.
La réponse de Monsieur Ashok Kumar Meena est exacte à un détail près : chez les plantes à croissance déterminée, la tige et ses rameaux se transforment en fleurs. En culture maraichère aux champs, les maraichers utilisent des cultivars de tomates à croissance déterminée. Par contre, en culture en serre, ces derniers utilisent de préférence des variétés indéterminées.
Determinate and indeterminate growth are two different patterns of growth exhibited by plants.
Determinate growth is characterized by a finite growth period during which the plant reaches a predetermined size or height. This type of growth is commonly seen in annual plants, where the plant grows vegetatively until it reaches a certain size, after which it transitions to the reproductive phase and produces flowers and fruits. Once the plant has reached its full size, no further growth occurs.
Indeterminate growth, on the other hand, is characterized by continuous growth throughout the plant's life. This type of growth is commonly seen in perennial plants, where the plant continues to grow and produce new leaves, branches, and stems each year. Indeterminate growth allows the plant to continue to increase in size and biomass over time.
In terms of plant structure, determinate growth often results in a compact, bushy plant with a defined shape and size, while indeterminate growth often results in a taller, more open plant with a less defined shape.
It's important to note that while many plants exhibit either determinate or indeterminate growth, there are also some plants that exhibit a combination of both types of growth. For example, tomato plants are typically classified as indeterminate but can also exhibit some determinate growth patterns depending on environmental conditions and management practices.
Determinate structures are analyzed just by the use of basic equilibrium equations. By this analysis, the unknown reactions are found for the further determination of stresses. Redundant or indeterminate structures are not capable of being analyzed by mere use of basic equilibrium equations.Determinate plants are triggered to produce all flowers in a certain time frame, despite many other factors. Indeterminate plants flower until some environmental condition triggers them to stop. For iteroparous species, those reproducing more than once, there are two growth strategies available: determinate growth, whereby growth ceases around/slows considerably after sexual maturity and indeterminate growth, which, at the most basic level, involves continued growth through life cycle. Determinate varieties require little or no staking of the plant. Indeterminate varieties develop into vines that never top off and continue producing until killed by frost. They are preferred by home growers and local-market farmers who want ripe fruit throughout the season. Plant growth in which the main stem continues to elongate indefinitely without being limited by a terminal inflorescence or other reproductive structure. Most plants demonstrate indeterminate growth, growing as long as the plant lives. In contrast, most animals and certain plant organs, such as flowers and leaves, undergo determinate growth, ceasing to grow after they reach a certain size.
