Effect of copper on the dynamics of the increment of plant dry mass and on some physiological processes in sunflower (Helianthus annuus L.)

Year: 2013

Type: article

Abstract: Experiments were undertaken in order to establish the influence of copper on the growth and yield of plants. Sunflower (Helianthus annuus L.) was grown in pots with peat enriched with mineral elements with the excluding of Cu. Copper was applied immediately after plant germination in doses of 0, 5 and 125 mg Cu per pot. In the form of CuSO4. During the vegetation period the following determinations were made: (a) dynamics of the increase of plant dry matter and of the assimilative surface, (b) chlorophyll content, (c) nitrate reductase activity and (d) intensity of photosynthesis and photosynthetic activity. The results indicate that copper deficit restricts the process of photosynthesis and the dynamics of dry mass increment. Differences in copper dosage did not have an immediate influence on the chlorophyll content and nitrate reductase activity, only rather an intermediate effect through the influence on the process of ageing.
