THE RESULTS OF STUDYING THE DYNAMICS OF THE CONTENT OF PLASTID PIGMENTS IN THE LEAVES OF THE TEA PLANT
225 KB
The work is dedicated to the study of plastid pigments changes in some tea leaves. For the main object of the study were used light green and dark green of Kolkheti and Kimyn forms (2n = 30) and their polyploidy analogies (4n = 60). From the research there was established the fact that the green pigment content increases, whilst the yellow one decreases. The content of chlorophyll «a» is much more in Kolkheti forms. In September the Kimyns content is the most in polyploidy forms. The content of Chlorophyll «b» in both forms place itself in the following sequence: dark green- light green. In July when the leaf age is 2,5 months, «a» and «b» chlorophyll correlation («a»/«b») is too high for all forms and varieties of Kolkheti anthocyanin forms Kimyn and exceeds the level set for C3-plants. This correlation gradually decreases as the leaf age increases and sets in the norms of C3 plant. And in September, when the leaves reach the age of 6 months, both varieties form contains the following: anthocyanin – polyploid – dark green – light green. The correlation of chlorophyll «a» and «b» change according to the leaf age and race. The correlation of chlorophyll and charotynoid is especially high in Kolkheti forms. According to this indicator, the best are the light green leaves. The knowledge of plastid pigment content dynamics of tea different forms gives us an interesting possibility of choosing selective forms.
