Natural herbs created from artificial seeds

摘要

Researchers in Guelph, Ont. are creating artificial herbal seeds to capitalize on the 500-million dollar North American mai-ket for herbs. French tarragon (a culinary herb), peppermint (used for tea that calms stomach indigestion) and lemon-scented geraniums (found in potpourri and perfumes) - which are normally propagated by cuttings - are their initial targets, with more to follow. "We are not trying to make the artificial seed the same as a true seed," says horticultural scientist Tissa Senaratna. "We are trying to make it better."
