These eggs hatch in 3–4 days and the juveniles take 9–10 days to reach maturity. The total life cycle takes 10–13 days [11] In susceptible varieties of Chrysanthemum, the female remains in one place within the leaf as it feeds on adjacent cells and continuously lays eggs. In resistant varieties, the female moves through the leaf laying ...
Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. [1] Plants are able to absorb essential elements through their leaves. [ 2 ] The absorption takes place through their stomata and also through their epidermis .
Puccinia horiana is a microcyclic, autoecious rust, meaning that the fungus has two known spore stages: teliospores and basidiospores, as well as no known alternate host. [6] Similar to other microcyclic rusts, two-celled teliospores produce unicellular basidiospores which are then dispersed via air currents.
The advantages here is that using the plant as a fertilizer has proven to increase crop yields. [5] T. diversifolia has the ability to restore phosphorus in high amounts to the soil. [21] T. diversifolia as a fertilizer contains 1.76% N, 0.82% P, and 3.92% K. All three properties are lower in cattle manure, and P is higher in poultry and swine ...
The leaves are light yellowish green, variously pinnatifid. The conspicuous daisy-like flowers are up to 20 millimetres (3 ⁄ 4 in) across, borne in lax corymbs. The outer, ray florets have white ligules and the inner, disc florets are yellow and tubular. It spreads rapidly by seed, and will cover a wide area after a few years.
External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. [1] It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.
The herb has a green, oblong leaf with pinnate venation. These leaves are about 5–7 centimetres (2–3 in) long and 4–6 cm wide. The leaf blade is broad, while the base is suddenly narrowed and of an ovate or lanceolate lobed shape. [7] The leaves are in alternate arrangement throughout the stem. [8]
Chromatomyia syngenesiae, the ragwort leaf miner or chrysanthemum leaf miner, [1] also known by the synonym Phytomyza syngenesiae, is a Palaearctic fly, also present in Australia and New Zealand, with larvae that make leaf mines in Senecio species and other related herbaceous daisies.
