Stimulating effect of low-temperature plasma on seed germination characteristics of trifolium repens

Abstract

The low temperature plasma (LTP) technology a new technology, uses for pre-sowing treatments. In this research work we used the new LTP technology equipment “low-temperature plasma modified instrument” and applied different doses in LTP technology to explore its effect on seed germination and other related characteristics on Trifolium repens crop seeds. The seed germination, germination vigor, plant fresh weight, plant dry weight, plant height and root length were significantly affected by LTP doses. The maximum seed germination (73.75%) recorded at LTP 120W treatment followed by 72% at 160W. In addition early germination was observed on same treatment, while minimum seed germination was recorded at 140 Watts LTP treatment. Maximum plant height (8.16mm) at 160W and maximum root length (74.14mm) was recorded at 180W followed by root length (73.89mm) at 160W. From our present work results, it is concluded that low temperature plasma dose 160W is an optimum dose to get high germination rate and healthy seedlings of Trifolium repens crop seeds.
