Ch.9 Structure of Woody Plants, Cross-Link Connections: The cambium…
-
Cross-Link Connections: The cambium recently formed in the Bocconia stem have produced more secondary xylem than secondary phloem. Because it has recently formed it has produced two or three layers of secondary xylem and one or two of secondary phloem. The primary xylem are visible which shows where the fascicular and interfasicular cambia arose
Cross-Link Connection: Tangential sections through a nonstoried vascular cambium of apple (malus sylvestris) and a storied vascular cambium of black locust (Robina pseudoacacia) show that the nonstoried fusiform individuals are extremely long and the ends are not aligned. in the stored cambium, fusiform initials are much shorter and occur in horizontal in rows.
Cross-link Connection: The bark of cork oak (Quercus suber) becomes extremely thick and is composed of mostly phellem, with few schlreids. Cork oaks grown in Portugal and Spain provide most commercial corks used to seal bottles. When the bark is sufficiently thick, the outer bark is peeled away and after a few years the bark is once again ready to harvest.
