Study of the Anatomical Growth Parameters of lentil Plant to Pre-soaked Seed treatment with Water Extract of Wolffia arrhiza

Abstract

Wolffia arrhiza is known as noxious weed and rated as one of the ten weeds growing country in South – East Asia, Commonly infesting natural impounded water in India. Studies have been made for their utilization in multiple ways in developing countries. Present study based on 24 hours pre-soaking seed treatment with control, 1,2 and 5% concentration of water extract of W. arrhiza for anatomical growth of stem of lentil plants variety DPL-15. The observation of stem show that the anatomical growth parameters like average diameter of stem, average thickness of stele, number of vascular bundles per microscopic field, average diameter of Xylem vessels, average diameter of Phloem is stimulated in seed treated with water extract for 24 hours. 5% level of water extract of W. arrhiza was found best for diameter of stem, number of vascular bundles per-microscopic field, and average thickness of stele. However for average diameter of Xylem vessels and average diameter of Phloem of lentil stem was observed better at 2% level of water extract of W. arrhiza. Results are statistically analyzed at 5% error probability.
