Post culture behavior: genetic and epigenetic effects and related problems,89; Read & Hosier, 1986; Stimart, 1986; Timmis & Ritchie, 1988; van Aartrijk & van der Linde, 1986). Typical off-type plants include dwarfs, color changes or mosaic patterns (e.g. chlorosis, loss of chimeras), growth habit changes (e.g. erectness, leaf shape, vigor), and changes in productivity (e.g

Marketing of micropropagated plants,onal, Inc., has indicated that in North America, . is the most-produced crop at 16 million units/year, ferns are second at 12 million units/year, and . is third at 10 million units/year (Chu & Kurtz, 1990). In 1988, the United States greenhouse and nursery industry did not show many sales increases

Commercial micropropagation in Western Europe and Israel,l tissue culture laboratories, of which 37 each produced more than one million plants per year. The total production of 1988 was 212.5 million plants. The most important categories of micropropagated plants are: pot plants (92.2 million), cut flower crops (37.8), fruit trees (19.4), and the bulbous

Commercial micropropagation in North America,propagated commercially for about 20 years, with applications to woody plants more recent. Production of tissue cultured plants has increased greatly since the first laboratory opened, but this expansion in production has not been steady. Instead, it could be described as proceeding sporadically wit

Commercial micropropagation in Asia,forest and woodland at 600 million ha, of which at least 1.8 million ha per annum were deforested between 1981 and 1985 (World Resources, 1986). Reforestation has been implemented, but only about 5.6 million ha were planted in the 1980s.

Micropropagation and plant tissue culture in developing countries of Africa,ducted in 23 countries and the findings are summarized in the two tables. The activities are concerned with micropropagation and plant improvement of food and cash crops. The state-of-the-art of tissue culture technologies in the economically most important African plants is reviewed briefly.
