Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. [1] Chlorophyll degradation during leaf senescence reveals the carotenoids, such as anthocyanin and xanthophylls, which are the cause of autumn leaf color in deciduous trees. Leaf senescence has the important function of ...
For best results, repot your plants in spring and choose a well-draining pot that’s just one or two sizes larger than the pot your plant is growing in. If the peace lily’s roots are tangled in ...
An albino corn plant with no chlorophyll (left) beside a normal plant (right) In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll.As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white.
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination ...
Lethal yellowing (LY) is a phytoplasma disease that attacks many species of palms, including some commercially important species, such as the coconut and date palm.In the Caribbean, it is spread by the planthopper Haplaxius crudus (former name Myndus crudus) which is native to Florida, parts of the Caribbean, parts of Australia and Central America.

More experimental field studies on plant-animal interactions regarding seed dispersal need to be conducted [9] [14] for a thorough understanding of seed dispersal syndromes. There is limited knowledge about the presence of elaisomes and ant behaviour affecting seed dispersal, and how ant-plant interactions evolved under various plant traits. [8]
Some plants may respond to more than one of these triggers. For example, Pinus halepensis exhibits primarily fire-mediated serotiny, [ 3 ] but responds weakly to drying atmospheric conditions. [ 4 ] Similarly, Sierras sequoias and some Banksia species are strongly serotinous with respect to fire, but also release some seed in response to plant ...
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
