Elongation in plants is primarily stimulated by the hormone auxin, which promotes cell expansion and growth in response to light and gravity. Auxin redistributes within the plant, causing cells on the shaded side of a stem to elongate more than those on the light-exposed side, resulting in phototropism. Additionally, environmental factors such as water availability and nutrient levels can also influence elongation by affecting overall plant health and growth conditions.
Stem elongation, seed germination, and flowering are primarily stimulated by the plant hormones auxins, gibberellins, and cytokinins. Auxins promote cell elongation and are crucial for directional growth, while gibberellins trigger seed germination by breaking dormancy and promoting growth. Cytokinins support cell division and are involved in regulating growth processes, including flowering. Environmental factors such as light, temperature, and water availability also play significant roles in these developmental stages.
The growth of stems and leaves is primarily stimulated by plant hormones called auxins, which promote cell elongation and division. Additionally, gibberellins play a crucial role in stem elongation, while cytokinins promote cell division and growth in leaves. Environmental factors such as light and water availability also significantly influence the growth of stems and leaves by affecting hormone production and distribution within the plant.
One cycle of elongation adds one amino acid to the growing polypeptide chain. Therefore, to produce a protein with 100 amino acids, 99 cycles of elongation are required, as the initial methionine is not incorporated through elongation but rather at the initiation step of protein synthesis.
MD Elongation (Machine Direction Elongation) refers to the stretching or deformation of a material along the direction of its production or processing, typically along the length of a film or sheet. In contrast, TD Elongation (Transverse Direction Elongation) measures the stretching perpendicular to the machine direction, across the width of the material. These properties are crucial in evaluating the mechanical performance and flexibility of materials, especially in applications like packaging and textiles. Understanding both elongations helps in optimizing material performance for specific uses.
The elongation of a tension specimen can be measured by marking a gauge length on the specimen before testing it and then comparing the final length of the specimen after it has been stretched to the original gauge length. The elongation can be calculated using the formula: Elongation = ((final length - original length) / original length) x 100%.

strain is percent elongation/100; for example a strain of 0.02 is 2% elongation. Often we refer to elongation at failure; for example if a material fails at 10% elongation its strain is 0.10
