Comparative Study of IR and UV-B Radiation Exposure on Germination, Biomass and Chlorophyll Content of Pisum sativum (L.)

Geeta [140] | Ashwani Kumar Goyal [2]

Abstract: In this field experiment a comparative study has been carried out on Pisum sativum (L. ) under the impact of UV-B (Ultraviolet-B) and IR (Infrared) radiation exposure. The seeds were pre-soaked for 24 hours in distilled water. Plants were grown in the field and exposed to supplemental IR (680-700nm) and UV-B (280-320nm) radiation for 1 hr regularly by the filtered sunlamp (300 watt) from sowing till seedling stage. The result showed significant decrease in germination percentage with UV-B radiation exposure. The length of plumul decreased significantly at UV-B radiation exposure while length of radical decreased higher by IR radiation exposure. The fresh weight, dry weight and chlorophyll content reduced significantly while chlorophyll a/b ratio highly increased at IR radiation exposure in comparison to the control plants.

Keywords: Pisum sativum, IR and UV-B radiation, seed germination, chlorophyll etc
