Abstract
The objective of this study is to evaluate the effect of UV radiation, different concenterations of Copper salts and auxin on the growth and productivity of linseed (Linum usitatissimum L.) using some morphological and phytochemical markers. Different treatment affects the growth and productivity of linseed differently in concentration dependent manner. UV radiation treatment affects the growth and productivity of the plant adversely by inhibiting the seed viability and plant productivity. The copper salt affects the growth and productivity of linseeds in concentration dependent manner. The low and medium concentrations of copper ions enhances the seed viability and conversion of seed to seedling without any promising effect on the growth and productivity of the plant but the higher copper concentrations adversely affect the seed germination plant growth and productivity. The auxin treatment show promising effect on the growth and productivity of the plant resulting in about 15 to 20% increment in productivity. The UV-B is adversely affecting the growth and productivity of plant by destabilizing DNA. The plant needs elements like copper for its growth and development as it is integral cofactor of large number of enzyme and coenzymes, electron carrier protein involved in essential metabolic activities of photosynthesis, respiration, DNA synthesis, gene regulation etc. But the presence of this essential element in high concentration may impose inhibitory influence on plant growth and productivity. Similarly the lower concentration of phytohormone auxin stimulate plant growth development and productivity but the concentration above optimal level impose adverse effect on linseed. Thus the knowledge of optimal dose of exogenously supplied micronutrient and growth regulator is essential to favorably induce the plant growth and yield
