Furthermore, uniform plant stands are easier to manage and harvest by machine. As a rule, chokeberry branches achieve the highest yields in the 5-6 year period, so cutting is not done again until the 7th year. [21] The aim of both the mechanical and the manual cutting system, is to let the shrubs grow into a closed hedge. While in the ...
Chokecherry, including the foliage, is toxic [6] to moose, cattle, goats, deer, and other animals with segmented stomachs , especially after the leaves have wilted (such as after a frost or after branches have been broken); wilting releases cyanide and makes the plant sweet. About 4.5–9 kilograms (10–20 pounds) of foliage can be fatal.
Sparganothis directana, the chokecherry leafroller moth, is a species of moth of the family Tortricidae. It is found in North America from Ontario to Florida, west to Texas and Michigan. [2] The wingspan is about 20 mm. Adults are on wing from June to August. The larvae feed on the leaves of Prunus virginiana. [3]
Stem cuttings of young wood should be taken in spring from the upper branches, while cuttings of hardened wood should be taken in winter from the lower branches. Common bounds on the length of stem cuttings are between 5–15 centimetres (2.0–5.9 in) for soft wood and between 20–25 centimetres (7.9–9.8 in) for hard wood.
Prunus avium, sweet cherry P. cerasus, sour cherry Germersdorfer variety cherry tree in blossom. Prunus subg.Cerasus contains species that are typically called cherries. They are known as true cherries [1] and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. P. serrula; some species with ...
Prunus ilicifolia flowers. It is an evergreen shrub [4] or small tree approaching 15 metres (49 feet) in height, [12] with dense, hard leaves [4] (sclerophyllous foliage). The leaves are 1.6–12 centimetres (3 ⁄ 4 – 4 + 3 ⁄ 4 inches) long with a 4–25 millimetres (1 ⁄ 8 –1 in) petiole [12] and spiny margins, somewhat resembling those of the holly.
It is a branching shrub with glossy dark green leaves that take on a red color in the autumn; it grows well in the sun and part-shade, often to heights of six feet (1.8 m) or more, forming clumps by means of stems rising from the roots. Its flowers are white or pink, appearing at the end of spring and producing black fruits in September. The ...
They can start new infections in new, green leaves and serve as the primary inoculum in each new growing season. The ascospores can stick to the leaf and, given a film of water and optimal temperature, germinate within hours of adhesion. Upon germination, hyphae can grow into the leaf via stomata (natural openings) on the underside of the leaf. [8]
