Vascular bundles
A. Contributes to flower death, fruit ripening and loss
B. Elongation of cells, ripening of fruit, inhibit dropping of fruit/leaves
C. Inhibits growth in times of stress and can induce dormancy of seeds
D. cause cell division and elongation, bolting, low levels lead to dwarfism
E. stimulation cell division and leaf growth, extend life of cut flowers
