Petal growth

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.

Rapid growth, showy flowers, and tasty seeds make sunflowers fun to grow as well as nutritious. The plants can grow to 10 tall. Individual flowers may reach 14" across, with golden petals and a brown center that becomes a mass of seeds by late summer. 

Flower buds die petals distorted growth stunted. Cause Thrips. Several species of tiny thrips infest irises Japanese irises are especially susceptible. Thrips feed on inner folds of leaves, causing stunted growth and russet or sooty areas on leaves. Tops of plants eventually turn brown and die. Flowers may appear discolored, flecked with white, or deformed. These pests are difficult to control, for they burrow into plant tissue. Don t buy sickly looking irises that may be infested. Remove and destroy severely infested plant parts. Use blue sticky traps to monitor and trap pests. Applications of insecticidal soap may provide some control once pests are spotted in traps. 

However, hydrothermolysis of resin-bound chain-like [Ti(02)(0H)(H20)J + species promotes exclusively ID growth along the c axis of the crystals due to ion-dipole interaction. This leads to the formation of petals (Figure 2.10) and rods (Figure 2.12).

E. grandiflorum was treated with chitosan solution and monosaccharides to enhance bud growth and petal pigmentation. Treatment with chitosan promoted processes in developing flower bud and enhanced the accumulation of anthocyanin in petals in vitro to increase the quality of the flowers (Uddin et al. 2004).
