Rose scale (order Hemiptera: family Coccoidea) Aulacaspis rosae – Mainly found on the stems and branches of the plant, lack of control will allow the pest to spread to flower stalks and petioles. At this point the plant would be stunted, spindly and with a white, flaky crust of scales on the bark.
White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [2] diverse host range and ability to infect plants at any stage of growth makes white mold a serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.
The stems are straight, red to grey-brown and studded with prickles. [3] The deciduous leaves are each made up of several widely spaced sharp-toothed leaflets up to 5 centimetres (2 inches) long. The inflorescence is a cyme of up to a few fragrant flowers with five petals in any shade of pink and measuring up to 2.5 cm in length.
Prickles and thorns are an evolved defense against herbivores — animals that eat plants — and can also aid in growth, plant competition and water retention, according to the study.
elongation of stems and leaves; weakening of cell walls in stems and leaves; longer internodes, hence fewer leaves per unit length of stem; chlorosis, a pale yellowish-white coloration. De-etiolation is the transition of seedlings from below-ground growth to above-ground growth form. [2]
Rosaceae (/ r oʊ ˈ z eɪ s iː. iː,-s i. aɪ,-s i. eɪ /), [5] [6] the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. [7] [8] [9] The name is derived from the type genus Rosa. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. [10]
The heartwood is golden to dark brown; the sapwood is white to pale brownish white. The heartwood is durable (its specific gravity is 0.7 – 0.8) and is very resistant to fungi, but the sapwood is readily attacked by dry-wood termites and borers. D. sissoo is known to contain the neoflavonoid dalbergichromene in its stem bark and heartwood. [5]
Fasciation (pronounced / ˌ f æ ʃ i ˈ eɪ ʃ ə n /, from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue ...
