Like seedlings, adult plant shade avoidance involves several mechanisms acting together. Petiole elongation is both a result of cell expansion and cell division, though not at the same stage in petiole and leaf formation. In newly growing leaves, cell division is the primary factor, while fully formed leaves and petioles rely on cell expansion ...
In simple terms, shade-tolerant plants grow broader, thinner leaves to catch more sunlight relative to the cost of producing the leaf. Shade-tolerant plants are also usually adapted to make more use of soil nutrients than shade-intolerant plants. [2] A distinction may be made between "shade-tolerant" plants and "shade-loving" or sciophilous ...
While these plants are relatively low maintenance, it’s not unusual for peace lily leaves to turn yellow here and there due to stress, pests, or other issues. This guide explains the most common ...
The plants, commonly known as centipede tongavine, pothos or devil's ivy, depending on species, are typically grown as houseplants in temperate regions. Juvenile leaves are bright green, often with irregularly variegated patterns of yellow or white. They may find host trees by the use of skototropism. [5] Spadix of Epipremnum pinnatum ...
Epipremnum aureum, the Pearls and Jade pothos, is a species in the arum family Araceae, native to Mo'orea in the Society Islands of French Polynesia. [1] The species is a popular houseplant in temperate regions but has also become naturalised in tropical and sub-tropical forests worldwide, including northern South Africa, [2] Australia, Southeast Asia, Indian subcontinent, the Pacific Islands ...
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".
These are carotenoids and they provide colorations of yellow, brown, orange, and the many hues in between. The carotenoids occur, along with the chlorophyll pigments, in tiny structures called plastids, within the cells of leaves. Sometimes, they are in such abundance in the leaf that they give a plant a yellow-green color, even during the summer.
Small water-soaked lesions, maturing into sunken and brown spots with or without a yellow halo. May show concentric rings with purple margins. Necrotic tissue may fall out to appear shot-holed. Leaf spot on many plants and crops. Septoria: Small brown spots, that turns light tan to white in the centre. Leaf spot on many crops Bipolaris
