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;
Etiolation / iː t i ə ˈ l eɪ ʃ ən / is a process in flowering plants grown in partial or complete absence of light. [1] It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color . The development of seedlings in the dark is known as "skotomorphogenesis" and leads to etiolated seedlings.
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 ...
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.
The uprooted tree falls, and a pit forms in the forest floor where the root mass and associated soil matrix used to be. Eventually after a period of time in which the roots decay, the associated soil matrix that was pulled out of the ground with the roots falls back to the ground, creating a corresponding mound. [1]
For most plants species the radicle dies some time after seed germination, causing the development of a fibrous root system, which lacks a main downward-growing root. Most trees begin life with a taproot, [ 3 ] but after one to a few years the main root system changes to a wide-spreading fibrous root system with mainly horizontal-growing ...
A law passed in 1982 was supposed to have created a permanent dumping ground for nuclear power plant waste − considered dangerous for thousands of years after its produced. Four decades later ...
Plants are susceptible to such localized calcium deficiencies in low or non-transpiring tissues because calcium is not transported in the phloem. [1] This may be due to water shortages, which slow the transportation of calcium to the plant, poor uptake of calcium through the stem, [ 2 ] or too much nitrogen in the soil.
