The changes of photosynthetic parameters, water use efficiency (WUE), fatty acid composition, chlorophyll (Chl) content, malondialdehyde (MDA) content, ATPase and acid phosphatase activities, fluoride (F) content, and leaf anatomical structure of two tea cultivars, “Pingyangtezao” (PY) and “Fudingdabai” (FD), after F treatments were investigated. The results show that net photosynthetic rate (P n), stomatal conductance (g s), and transpiration rate (E) significantly decreased in both cultivars after 0.3 mM F treatment, but FD had higher P n, g s, and WUE and lower E than PY. Chl content in PY significantly decreased after 0.2 and 0.3 mM F treatments, while no significant changes were observed in FD. The proportions of shorter chain and saturated fatty acids increased and those of longer chain and unsaturated fatty acids decreased in both cultivars under F treatments. The contents of MDA increased after F treatments but were higher in PY than in FD. In addition, F treatments decreased the activities of ATPase and acid phosphatase and increased F content in both cultivars; however, compared with PY, FD showed higher enzymatic activities and lower F content in roots and leaves. Leaf anatomical structure in FD indicated that cells in leaf midrib region were less injured by F than in PY.

“…Ontogenetically, initiation of laticifers within the embryo concomitant with organization of primary tissues would suggest that laticifers do not constitute isolated cellular structures comparable to various forms of excretory, tracheoid or sclerenchymatous idioblasts (Foster, 1956). It must be emphasized that laticifers do not arise from cell" which are dispersed within different tissues, as the secretory cells of Pinus (Spurr, 1950), of Ricinus (Bloch, 1948), or isolated occurrence of sclerenchymatous idioblasts within stem, or leaves (Foster, 1944(Foster, , 1955. Initiation of non-articulated laticifers from a specific aggregate of meristematic cells of the embryo suggests that they can be interpreted collectively as a particular cellular tissue or possibly a tissue system.…”

Mahlberg, P. G. (U. Pittsburgh, Pittsburgh, Pa.) Embryogeny and histogenesis in Nerium oleander. II. Origin and development of the non‐articulated Iaticifer. Amer. Jour. Bot. 48(1): 90–99. Illus. 1961.—Laticifer initials, collectively considered as a laticifer system, are differentiated in the globular embryo from meristematic cells which occupy a position within the potential procambial tissue. A total of usually 28 initials, in Nerium oleander, arise as an irregular ring of cells directly below the embryonic shoot apex, during initiation of the cotyledonary primordia. No anastomoses occur between laticifer initials. During subsequent development of the embryo, the laticifer initials grow in a bi‐directional manner and penetrate into the root, cotyledons and toward the shoot apex. Upon enlargement the initials bifurcate repeatedly, many branches penetrate into the cotyledons, others grow into the cortex of the hypocotyl or penetrate between cells of the procambium. Repeated nuclear divisions within each initial result in the formation of a multinucleated protoplast in this cell type. The tips of laticifers occupy intercellular spaces during their growth; they do not penetrate into or through adjacent cells. A plexus of laticifer branches is formed within the cotyledonary node of the mature embryo. No new initials are formed during subsequent growth of the plant, rather certain branches from the cotyledonary nodal plexus penetrate into the enlarging shoot system. The nature of their growth habit and branching suggests that the tips of laticifer initials exhibit an intrusive form of growth.

“…This conspicuous tissue, comprising the Querparenchyma of Mahlert (1885) and other German investigators, was designated by Worsdell (1897) as "accessory transfusion tissue." Most of these cells are fusiform but some show slight branching and may be classified as osteoselereids (Tschirch, 1885;Foster, 1944). This tissue is very similar in structure to the corresponding tissue in the leaf of Acmopyle.…”
