7 lut 2022 · In the case of smaller leaves, petioles tend to be shorter, to have an outline with an indentation and have narrower vessels. Indeed, environmental factors may directly influence distinct plant organs, but our results appear to reveal a different pattern for petioles that relates to the leaf itself.
24 sty 2020 · All the leaves in the crown were cut by cutting the petiole as close as possible to its insertion point with the stem and placed immediately in plastic bags within coolers. One to five fully expanded leaves per tree—hereafter called A-leaves—were kept for the anatomical studies.
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.
6 mar 2018 · Lastly, strong petioles were associated with durable leaves, as approximated by specific leaf area. This study reveals meaningful patterns in fern leaf biomechanics that align with species leaf size, sterome attributes and life-history strategy.
2 kwi 2021 · Petioles are important plant organs connecting stems with leaf blades and affecting light-harvesting leaf ability as well as transport of water, nutrient and biochemical signals.

13 kwi 2022 · Background and aims: 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.
