Experimental studies on the seed germination of a few wild flower species for the establishment of amenity vegetation

Abstract

In this first stage of a study aiming at the development of a technique for the establishment of a visually attractive green area, germination tests were made on seeds of four wild flower species under varying conditions of temperature in the laboratory.
The results of the tests are as follows:
Percentage germination of Ixeris dentata was very low (only 2.8% at 20°C) in direct seeding after collecting. But wet storage at low temperature gave good germination (76.5% at 10°C after 3 months storage at 5°C).
Seeds of Ranunculus japonicus, Cllrysanthemurn leucantheinum, and Lotus corniculates var. Japonicus could germinate after harvest with high percentage, respectively 78% at 5°C, 95% at 25°C, and 80-90% at 10-25°C 25°C. This good germination ability can be kept in dry storage. Seeds of Ranunculus must be controlled at lower temperature, preferably is 0-5°C.
