Show Great Vitality of Seeds Proved by Experiments Here's weed news for the farmer, but it's bad. Seeds of wild morning glory, buried for 30 years, sprouted almost at once after being unearthed and planted, the United States Department of Agriculture Agricul-ture reports. The seeds were buried as part of an experiment to discover how long seeds may lie In the soil and still grow, and to discover how long seeds must be buried to be killed. The morning glory will be given further fur-ther opportunity to prove its "staying power," as some seeds buried 30 years ago are still in the ground and will not be removed for ten more years. |
