NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cuttings. It is also used for plant tissue culture. [2] The hormone NAA does not occur naturally, and, like all auxins, is toxic to plants ...
Step 1: Take a Cutting. Cut a four-inch-long piece of the plant you wish to propagate, making sure to include at least one node—this is the area on the plant where new growth occurs. On vining ...
Indole-3-butyric acid (1H-indole-3-butanoic acid, IBA) is a white to light-yellow crystalline solid, with the molecular formula C 12 H 13 NO 2. It melts at 125°C in atmospheric pressure and decomposes before boiling. IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking.
Plant hormone. Lack of the plant hormone auxin can cause abnormal growth (right) Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, [1] the regulation of organ size, pathogen ...
Plant development. Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very early ...
A grafted tree showing two differently coloured blossoms. Grafting or graftage[1] is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion (/ ˈsaɪən /) while the lower part is called the rootstock.
Helichrysum petiolatum D.Don. Helichrysum petiolare, the licorice-plant[2] or liquorice plant, is a species of flowering plant in the family Asteraceae. It is a subshrub native to the Cape Provinces of South Africa — where it is known as imphepho — and to Angola, Zambia, and Zimbabwe. [1] It is naturalized in parts of Portugal and the ...
