X-ray microanalysis has been used to determine the elemental composition of oil-palm (Elaeis guineesis) cell suspensions without the use of cryoprotectants. Results based on individual cells were gathered over a typical growth cycle of 14 d. During the log phase (5-7 d) there is an increase in the n

โฆ Synopsis
Suspension cultures of oil palm (Elaeis guineensis Jacq.) were established in a medium with 80 or 100 mg.l(-1) 2,4-dichlorophenoxyacetic acid and 1 g.l(-1) activated charcoal, from calli producing embryogenic cells and protruding proembryos. The suspension was composed of meristematic clumps, breaking away and giving rise to new smaller aggregates. Under the best conditions, the initial weight increased about 4 fold in one month. Embryo differentiation was achieved when plating the clumps either directly, or after a phase in hormone-free liquid medium. In the second case, early maturation occurred in liquid medium. Secondary embryogenesis was reduced, and up to 18.1 % embryos formed shoots. Rooted plants were sucessfully transferred to soil.

Protoplasts were isolated from immature inflorescence-derived embryogenic suspension cultures of two cultivars of Sorghum vulgare. The protoplasts were cultured in a modified K8P liquid medium. They started to divide after 4-5 days of culture, and achieved 16.8% division frequency by 10 days. Protoc
Coffee plants were regenerated from protoplasts isolated from embryogenic cell suspension cultures derived from somatic embryos ofCoffeaarabica L. cv. caturra. Yields of viable protoplasts ranged from lx105 to 6x105 protoplast/g fresh weight. Protoplast preparations usually contained no contaminati
