Abstract

Juice vesicles of Valencia orange were grown on agar bases containing different concentrations of kinetin plus mineral and organic constituents, or in comparable liquid solution (shake cultures), maintained at approximately 26 C. Shake cultures enlarge most rapidly, but both maintain similar patterns of anatomical development. Typically, marginal parenchymatous cells of the sac become meristematic and develop, largely by periclinal division, generalized cambial meristems that enlarge the callus by the addition of linear rows of cells. Chloroplasts and wound tracheids with bordered pits mature within 30 days, but to date no further differentiation has been noted. Surface cells frequently enlarge, detach, and grow into branched hyphal aggregations of cells. Media containing 1.0 mg/liter kinetin causes greater enlargement of callus than media with 0.02 mg/liter kinetin.
