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.
Sempervivum (/ s ɛ m p ə ˈ v aɪ v əm / [1] [2]) is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks.Other common names include liveforever (the source of the taxonomical designation Sempervivum, literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well.
In developmental biology, photomorphogenesis is light-mediated development, where plant growth patterns respond to the light spectrum.This is a completely separate process from photosynthesis where light is used as a source of energy.
It is cultivated as an ornamental plant for use in drought tolerant and succulent gardens, and in container gardens. It is also suitable for growing indoors as a houseplant if provided with full-exposure, sunny windows or grow lights, to prevent etiolation. [3]
The IOS focuses on global research and conservation of the succulent plant families (Agavaceae, Aloaceae, Cactaceae, Crassulaceae, Portulacaceae, Talinaceae). [3] It later became the first plant conservation organization with a strict code of conduct for all members to follow, detailing principles to conduct field research, specimen collection ...
Crassulaceae are generally herbaceous but there are some subshrubs, and relatively few treelike, epiphytic (growing on surface of plants), scandent (vine like) or aquatic plants. [3] [4] Most species are herbaceous leaf succulents, with regular 5 part (pentamerous or fivemerous) flowers, isomerous free carpels and one or two whorls of stamens. [5]
Aeonium, the tree houseleeks, is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae.Many species are popular in horticulture. The genus name comes from the ancient Greek αἰώνιος / aiōnios (ageless). [1]
Curio herreanus, syn. Senecio herreanus, which is also known as string of watermelons, string of beads, gooseberry plant and string of raindrops, is a flowering succulent plant in the daisy family Asteraceae that is native to Namibia. [1]
