Description Developmental pattern, growth and branching behaviour of rhizomes of ginger were studied. Axillary buds are present at each node. Secondary and tertiary branches originated from the axillary bud from the adaxial sides of the leaf or scale leaf. Cytohi tological zonation of rhizome buds and adventitious roots was studied. The phloem mother cell in ginger originated from the primary thickening meristems. he sieve tubes develop by pycnotic degeneration of nuclear structure. The fragmen ed multinuclear stages were observed in several sieve tube members. The sieve el ment has an average length of 76.8 µm and width of 8.76 µm. The sieve plates are transverse to oblique with varying degrees (110-140°) of inclination. Slime body exists only in early stages of development. No definitive callose was served in mature sieve tube. The number of companion cells per sieve tube member varied from four to eight; these showed dense cytoplasm and prominent n lei. Phloem parenchyma and fibres were also present.
