Spindly growth, also known as leggy growth, is a term used when two plants compete for sunlight and nutrients in order to develop. Causes
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.
1. Leggy Stems. While more common when starting seeds, stretched out, leggy stems can also be an issue with houseplants. The stems grow longer, and the space between leaf nodes elongates as the ...
Growth may be impacted by lower light, producing leggy growth. The growth can also be impacted by the invasion of non-native plants. [5] Chrysocephalum semipapposum was found to inhibit the process of nitrification in the rhizosphere, when compared to non-rhizosphere soil. [35] The rhizosphere is the soil surrounding the plants roots. [36]
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
After germination, seedlings must grow quickly to escape floodwaters; they often reach a height of 20–75 cm (up to 100 cm in fertilized nursery conditions) in their first year. Seedlings die if inundated for more than about two to four weeks. Natural regeneration is therefore prevented on sites that are always flooded during the growing season.
The affected plants, which are visibly etiolated (long and weak stems), chlorotic (lacking chlorophyll), and which are at best infertile with empty panicles, producing no edible grains; at worst, they are incapable of supporting their own weight, topple over, and die (hence "foolish seedling disease").
The epigenetics of plant growth and development refers to the heritable changes in gene expression that occur without alterations to the DNA sequence, influencing processes in plants such as seed germination, flowering, and stress responses through mechanisms like DNA methylation, histone modification, and chromatin remodeling.
