Plant Growth: Growth is an essential, natural and irreversible factor. As living beings, every plant grows but unlike humans, plants have unique characteristics of growth. They grow throughout their life. Plant growth takes place in a systematic manner. This systematic mannerism of growth is defined as development in plants.

Plant growth is an irreversible and permanent increase in the size of the plant parts, organs, tissue, entire plant or an individual cell. Growth is the most fundamental characteristic of living plants, similar to any other living organism. Plant growth is also accompanied by metabolic processes such as catabolism and anabolism that require spending energy.

Stages of Plant Growth

It’s a quantitative parameter and refers to an unrecoverable increase in the size or weight of a cell, towel, or organ. Plants can grow throughout their lives due to meristematic tissues present in the specific corridors.

Growth can be measured by increasing cell number, length, area, volume, and dry or wet weight.

• Primary Growth – Apical meristems of roots and shoots are responsible for rapid growth.

• Secondary Growth – Secondary growth is due to side meristems, e.g. vascular and cork cambium. The factory increases in circumference due to secondary transition.

The various stages of plant growth include

Seed Germination – The seed needs water, oxygen, and optimum temperature for its germination. A temperature of 24-32 ℃ is optimum for germination. Water hydrates the enzymes and food inventories, and the seed becomes actuated.

Vegetative and Growth – The roots crop from the seed, and the vegetative stage begins. The most precious growth occurs during the vegetative phase, and it continues unless dammed by environmental change.

Reproductive Stage – This is the final stage where the factory produces flowers, fruits, and seeds. The plants require different nutrients similar to phosphorus and potassium at this stage.

The following are major elements influencing plant growth

• Temperature: As the temperature rises, growth accelerates.
• Light: Light intensity, duration, and quality all have an impact on various physiological processes that occur in plants.
• Water: Water is necessary for plant development. They thrive in adequate amounts of water. They even respond to water scarcity.
• Plant Growth Regulators: Auxin, cytokines, gibberellins, and other plant growth regulators are used to control plant growth.
• Soil Nutrients: Plants require a sufficient amount of nutrients to flourish properly. Plant development is influenced by the quality and amount of nutrients.
