Petioles are important plant organs connecting stems with leaf blades and affecting light-harvesting ability of the leaf as well as transport of water, nutrients and biochemical signals. Despite the high diversity in petiole size, shape and anatomy, ...
The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be sessile.
17 gru 2016 · Petiole Function. Since leaves are responsible for fueling plants through photosynthesis, the petiole serves to transport the energy made in the leaf to the rest of the plant. It also serves to transport nutrients and water that are absorbed by the roots and passed up through the xylem, to the leaf.
5 dni temu · As the single link between leaves and the rest of the plant, petioles must develop conductive tissues according to the water influx and sugar outflow of the leaf lamina. A scaling relationship between leaf area and anatomical traits of xylem and phloem is expected to improve the efficiency of these tissues.
