Plastid Transformation in Carrot Roots Induced by Different Lights

Mercedes Wrischer ; Hrvatska

Abstract

The effect of red (660—670 nm), blue (450 nm) and white light on the development of chloroplasts in carrot roots and callus tissue has been investigated.
The experiments indicate, that the rate of the greening of the tissue and the size of the chloroplasts are dependent on the wavelength of the light used, because the chloroplasts develop somewhat later and are smaller in red than in blue or in white light.
The electron microscope has, however, shown that there is no significant difference in the effect of different lights on the ultra- structural changes, in which the inner plastid membrane plays a dominant role in the formation of membrane material of the newly formed thylakoids.
