Özet

c) While a soft, white or dirty white callus was usually formed at the sides of the explants, some explants had small, compact masses of green calli at the cutting ends. d) Although shoot regeneration was not observed In the tissues but growth centers were present. e) Four phenolics belonging to the phenylpropan group were determined in calli grown under photoperiodic or dark conditions. The accumulation rate of these phonolics was not affected much with photoperiodic and dark treatments. 4. Peach a) Regardless of hormone combinations tested the highest callus formation was observerd in explants taken in September (194.9 mg In average) when compared to explants taken In June (122,3 mg in average) b) The four different hormone combinations tested in the experiment did not differ in regard to callus formation. c) Callus formation was higher under dark composed to the photoperiodic treatment during the same culture period. Callus formation at the upper part was more compact and completely covered the surface. d) Shoot regeneration was not observed during the culture period but a clear xylem tissue formation was seen in the tissue sections. e) Four different phenylpropane and four different flavonoid compounds were determined In the callus tissues. A correlation between photoperiodic and dark conditions and the intensity of accumulation of these compounds was not present. 1495. Cherry a) No significant difference existed between the four different NAA-BAP combinations tested in the experiments. b) Explants taken in September had a higher callus formation rate (256 mg in average) than explants taken in June in which callus formation rate was 132 mg in average. c) Photoperiodic or dark conditions had no significant effect on callus formation rate. d) Callus colour was yellowish green in photoperiodic conditions and grayish white in dark conditions and a scattered callus formation was observed between explants. e) Again, shoot regeneration was not observed but growing center could be seen in tissue-sections. 150c) While a soft, white or dirty white callus was usually formed at the sides of the explants, some explants had small, compact masses of green calli at the cutting ends. d) Although shoot regeneration was not observed In the tissues but growth centers were present. e) Four phenolics belonging to the phenylpropan group were determined in calli grown under photoperiodic or dark conditions.
