“…Skoog (1935) showed, relatively early in the study of auxins, that inhibition of stem elongation by Xvradiation could be essentially completely prevented by concurrent auxin treatments. It has been found, using the type of kinetic analysis advocated here, that inhibition of growth of tissue cultures by Xsirradiation also could be quantitatively prevented by auxin treatment (Klein and Vogel, 1956). The more recent work of Gordon (1957) has shown that the principal effect of the X rays is on biosynthesis of auxin.…”

LOCKHART, JAMES A. (U. Hawaii, Honolulu.) Interactions between gibberellin and various environmental factors on stem growth. Amer, Jour. Bot. 48(6): 516-525. Illus. 1961.-The interactions between gibberellin and various environmental factors on stem elongation of greenhouse. grown Phaseolus vulgaris have been studied in steady-state growth systems. The action of gibberellin was found to be independent of rate of accumulation of photosynthetic products, root activity, temperature, water availability and both ultraviolet and Xvradiation. It was also shown that gibberellin interacts completely with red/far-red radiation given at the end of the daily light period. This interaction is complete even when maximum growth rates are experimentally reduced by limiting various independent factors. These results are interpreted as demonstrating that red/farred radiation controls rate of stem elongation in greenhouse-grown plants through an effect on the endogenous gibberellin system of the plant. None of the other environmental factors studied seems to act through the gibberellin system.

“…If this is the case, however, the dark-grown cultures would have a subthreshold level of endogenous auxin, resulting in reduction of secondary embryogenesis. Similarly, Klein & Vogel (1956) showed that gamma radiation lowered the endogenous level of auxin in plant tissues. Whether this is the cause of the reduction of secondary embryogenesis in gamma-irradiated B. napus secondary embryoids, as shown by our results, has yet to be investigated.…”

SUMMARYSecondary embryogenic potential of winter oilseed rape, Brassica napus ssp. oleifera (Metzg.) Sinsk. cv. Primor, was maintained for over six years without diminution. Cytological analysis of 22 randomly selected secondary embryoids showed that they were all haploid. Many factors affect secondary embryogenesis in culture. The frequency of secondary embryogenesis was enhanced by the incorporation of 15 g T^ sucrose into the medium; sucrose at 60 to 120 g 1"î nhibited secondary embryogenesis. Incubation in continuous darkness or continuous light led to a marked suppression of secondary embryogenesis. The best light regime for secondary embryogenesis was 16 h light/8 h dark. Incorporation of activated charcoal into the culture medium and the application of gamma radiation suppressed secondary embryogenesis. Further secondary embryogenesis was significantly reduced when only part of the secondary embryoid was cultured. The results discussed are based on the possibility that endogenous growth regulators may be involved in the initiation of secondary embryoids.
