Badania poziomu RNA podczas kiełkowania i wzrostu korzenia kukurydzy (Zea Mays L.). I. Zmiany poziomu RNA w całym korzeniu

Abstract

It has been found that during the 14 days period of germinatlon and development of corn the RNA content in the whole root increased almost 4 times in comparison with the control root (2 days). These changes are statistically significant. The highest increase of the RNA content and the dry mass of the root has been observed during the first 6 days of development. The araount of rRNA and tRNA has changed in the same way. The rate of the increase of their content in comparison with the control root (2 days) was eąual and it suggest that in the tested period of development the rRNA and tRNA are synthetised with equal speed.
