Abstract

Trigonella foenum graecum (fenugreek) seeds were treated with different dilutions of aqueous leaves extract of Antigonan (i.e., from 10 to 50%) and grown on sterile cotton and Whatman filter paper in a Petri dish. The seedling length, fresh weight and dry weight of plants was taken after 5 to 15 days. It was found that the germination was 62% (85% in distilled water control and the germination process was completed in 2 days) in all dilutions and growth was severely inhibited as compared to distilled water grown control. Growth inhibition was increases with extract concentration. Maximum inhibition was recorded in radicle growth after five days of sowing in treated seedling with 50% aqueous extracts. Qualitative LCMS analysis of methanolic leaf extract of A. leptopus reveals the presence of various phenolic acid derivatives, like ferulic acid derivatives, arachidonic acid, citronellic acid, and coumarins derivatives etc. These phytotoxins not only inhibits the germination but also plant growth and interfere with ion accumulation of the plant. These results indicate that Antigonan plants have strong negative allopathic interactions with Trigonella. Antigonan may be harmful for our crop as well as native plants. However, the plant has certain medicinal properties like anti-cancerous properties, anti-diabetic properties that can be utilized for human welfare.

Coral vine Antigonon leptopus belonging to the family Polygonaceae known as queen’s wreath
Trigonella foenum-graecum grown under the extract of Antigonan leptopus leaf extracts and various parameters were studied
It was observed that there is marked seed germination and seedling growth inhibition occur in all different dilutions of extract

Summary

Introduction

Coral vine Antigonon leptopus belonging to the family Polygonaceae known as queen’s wreath. Test plants might show negative interaction to the wild plants that grows in a particular habitat. It is categorized as alien species/nonnative because its spread in an area linked with the intentional or accidental introduction of human activity [16, 23]. Invasive plants released certain chemicals that suppress cell differentiation, growth and development of other plants. Produces certain chemicals that have pharmacological importance and used for various medicare purposes. It is effective against diabetes, liver and spleen disorder, asthma cough and throat constriction [8, 10, 15]. Eustatius and this but it has been interfered with migrating crabs [3, 7, 22]
