Oxalis triangularis, commonly called false shamrock, is a species of perennial plant in the family Oxalidaceae. It is native to several countries in southern South America . This woodsorrel is typically grown as a houseplant but can be grown outside in USDA climate zones 8a–11, preferably in light shade.
In biology, nastic movements are non-directional responses to stimuli (e.g. temperature, humidity, light irradiance) that occur more rapidly than tropisms and are usually associated with plants. The movement can be due to changes in turgor (internal pressure within plant cells). Decrease in turgor pressure causes shrinkage, while increase in ...
Dormancy should not be confused with seed coat dormancy, external dormancy, or hardheadedness, which is caused by the presence of a hard seed covering or seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol ...
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.

Oxalis triangularis. Several species are grown as pot plants or as ornamental plants in gardens, for example, O. versicolor. Oxalis flowers range in colour from whites to yellow, peaches, pink, or multi-coloured flowers. [11] Some varieties have double flowers, for example the double form of O. compressus.
Photoblasticism is a mechanism of seed dormancy. Photoblastic seeds require light in order to germinate . [ 2 ] Once germination starts, the stored nutrients that have accumulated during maturation start to be digested which then supports cell expansion and overall growth. [ 3 ]
Original - Oxalis triangularis (also known as the love plant or purple shamrock) is a classic example of a plant which responds with movement to an external stimulus. The leaves open and close in response to varying light levels with the result that they are open during during the day and close at night.
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]
