Diurnaland seasonal changes of starch contents in cotton leaves and pedicle of leaves
In this paper the results of analysis of starch contents in the leaves and its pedicle of longstable cotton are present. Is established that the starch contents in cotton leaves and cridle of leaves is regularly changed on the time of day and in the developmental phases of plants. The high starch contents is observed in the morning and in the noon the concentrations of this carbohydrate sharply is decrese. In the second half time of day the starch content repeatedly increase, but it concentration is low than in the morning. In the developmental phases the high concentration of starch observed in the period of plant squaring-flowering.
