Abstract


Quality is a major component of light that affects the plant pigments. The effect of blue, green, and red parts of the white light was studied independently to evaluate the role of individual light in germinating wheat as compared to white light as a control. Chlorophyll a was exhibited in response to green, red, and blue light in decreasing fashion (5.446, 4.226, and 3.636, respectively) as compared to the effect of white light, showing a stressful condition where normal contents were more compared to others (6.992). Similarly, chlorophyll b contents were also decreased in similar trends in response to green, red, and blue (4.320, 3.787, and 2.081, respectively) as compared to the effect of white light (5.666). Proline contents observed in response to varied light showed a little stressful effect in the case of blue light. All other conditions were similar to those of the control. Carotenoid and anthocyanin content exhibited different responses to varied light as compared to white light. Carotenoid showed more content (4.744) in red light, similar to the control, but anthocyanine exhibited more content in blue and green light (2.943, 5.356). When all the conditions were subjected to Indole-acetic acid, a dramatic increase in the pigment contents of all the types was observed, showing a mitigating effect of growth hormone. Presoaking the seed in Indole acetic acid before sowing may be recommended for the potential research activities in the future.
