7 lut 2022 · Our results showed that leaf area has the strongest influence on petiole anatomical traits, more than temperature, precipitation and plant height, emphasizing the supportive and mechanical role of this part of the leaf. Petioles tend to be longer and have a circular outline in larger leaves.
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.
The celery plant is characterized by enlarged, tender, edible petioles or leaf stalks. The petioles are broad, with sheathing bases, and consist mostly of parenchyma and collenchyma strands. These are associated with vascular bundles under the epidermis in the abaxial surface which is prominently ridged, whereas the adaxial surface is smooth.
