Summary
[edit].jpg&action=edit§ion=1){kind=link}
| Description |
Cross section: Cucurbita Common name: Pumpkin/Squash Magnification: 400x Like most herbaceous dicots, Cucurbita is capable of limited amounts of secondary growth. The vascular bundles are bicollateral; the central xylem is bound by an inner and outer cambium, and topped by a larger outer and a smaller inner phloem. Sieve tubes, companion cells and phloem parenchyma are clearly evident the phloem. Xylem is well developed with numerous protoxylem evident towards the inside, and very large metaxylem to the outside of the bundles. Xylem consist primarily of large vessels and xylem parenchyma; tracheids and fibers are rare. Secondary vascular tissues are present but often difficult to distinguish from the primary. The vascular bundles are separated by zones of internal parenchyma. |
