Tea flowers are globular, about 3 to 5 cm in diameter, white, and delicately fragrant. They are borne in the axils of scale leaves (small leaves that do not develop further) and may occur singly or in small clusters. There are five to seven petals and an equal number of sepals. The flowers are mostly self-sterile and are produced in cycles corresponding to leaf growth, and require 9 to 12 months to form mature, round seed pods 1 to 1.5 cm in diameter. The tea plant is not generally allowed to flower during production cycles, with only a small number of the plants allowed to go to seed production to maintain seed stock. 

Tea leaf growth occurs in a definite and distinctive cycle.17 A typical cycle begins with the formation of a small (5 mm) leaf bud that swells but...

The physiology of metal toxicity in plants has been reviewed by Foy et al. (1978). The most widely described effects of metal toxicity in plants are inhibited root growth, depressed shoot and leaf growth, and general chlorosis of the younger leaves (Bradshaw and McNeilly, 1981 Baker and Walker, 1989). Literature on the relative toxicities of different metals to different species is limited to a few, mostly species-specific studies.

The essential oil content during the different stages of leaf growth revealed that the eugenol content in the leaves increased from 38.3 to 95.2% with maturity, while the contents of eugenyl acetate (51.2 to 1.5%) and caryophyllene (6.3 to 0.2%) decreased (Gopalakrishnan and Narayanan, 1988). Clove bud and leaf oil contain various classes of compounds, e.g. monoterpenes, sesquiterpenes, aldehydes and ketones (Vernin et al., 1994), which are indicated in Table 8.8.

The life cycle of the potato plants cultivated today is completely asexual (i.e., tuber to sprout to plant to tuber). When rapid leaf growth slows down, the plant begins to form flowers, and underground stems (stolons) begin to branch out and swell at their tips. Sucrose is sent from the mature leaves, the sources, to the rest of the plant and the stolons, the sinks. The starch is deposited at the ends of the stolons, forming tubers.
