Spindly growth, also known as leggy growth, is a term used when two plants compete for sunlight and nutrients in order to develop. ... Why Vegetable Plants Are Spindly;
The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule ...
Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods.
Plants are produced using material from a single parent and as such, there is no exchange of genetic material, therefore vegetative propagation methods almost always produce plants that are identical to the parent. In some plants, seeds can be produced without fertilization and the seeds contain only the genetic material of the parent plant.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
A study published in July found that over 40% of self-identified gentle parents teeter toward burnout and self-doubt because of the pressure to meet parenting standards.
The most telltale symptom of Bakanae is the tall, spindly look of the plant. This is a result of the gibberellins, or growth hormones, the fungus secretes. [ 2 ] Infected plants are easy to pick out, then, as they often rise above the rest of the healthy plants with regularly secreted growth hormones.
