2 Νοε 2020 · Summary. Roots are typically branching cylindrical structures that develop underground to facilitate extraction of moisture and nutrients from the soil, often in association with hyphal networks of soil-dwelling fungi.
31 Οκτ 2010 · Introduction. Fasciation (or cristation) is a variation that may occur in the morphology of plant organs and typically involves broadening of the shoot apical meristem, flattening of the stem and changes in leaf arrangement. The term fasciation comes from the Latin fascis meaning a bundle.
Both leaf and flower fascicles occur among Angiospermae, often as adaptations facilitating pollination, such as in many Lamiaceae, of which some Lavandula are typical. Other plant fascicles are adaptations to achieve greater compactness for defensive reasons.
The functions of roots include: Anchoring the plant in the soil (and stabilizing the soil). Supporting the upright growth of the plant. Providing a site for the symbiotic relationship of the plant with particular beneficial fungi and bacteria. Absorbing water and dissolved minerals from the soil.
19 Ιαν 2022 · Clarifying the linkages between various root traits and critical root functions (e.g. absorption and transportation capacity) across species is the first step in dissecting the complicated roles of roots in plant and ecosystem functions (McCormack et al., 2015; Roumet et al., 2016; Freschet et al., 2017, 2021b).
27 Ιουλ 2022 · Perfect flowers may be capable of self-pollination. Pollen produced within the flower may fall on a stigma in the same flower, and the sperm that it carries may fertilize the egg in the ovule. Sometimes, the timing of events during the stages of flower maturation encourage self-pollination.
5 Μαρ 2009 · The main functions of root systems are also explored including how roots cope with nutrient acquisition from the heterogeneous soil environment and their ability to form mutualistic associations with key soil micro-organisms (such as nitrogen fixing bacteria and mycorrhizal fungi) to aid them in their quest for nutrients.
