The effects of five cytokinin antagonists on the growth
of cytokinin-autonomous lines of Phaseolus lunatus cv.
Kingston, Phaseolus vulgaris cv. Great Northern, and
Nicotiana tabacum cv. Wisconsin 38 callus tissues have been
compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines
bearing the following N⁴ side chains, 4-n-pentyl-
(ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...
A full range of experiments was carried out to investigate the
effects of environmental factors on the terminal bud dormancy in two
high-elevation true fir species, Shasta red fir (Abies magnifica A.
Murr. var. shastensis Lemm.) and noble fir (A. procera Rehd.),
seedlings. Photoperiod, thermoperiod and moisture stress were of...
EDLAN is a simple, inexpensive local area network suitable for
educational applications. In EDLAN, a number of personal computers are
connected through an RS-485 global bus which carries the data
transmission among the computers. CSMA/CD protocol is used to control
the access of the global bus. The communications are controlled...
