Effect of bulb circumference on bulb yield and bulblet formation capacity of Sternbergia lutea (L.) Ker-Gawl. Ex Sprengel (Winter Daffodil)

Abstract

In this study, bulb yield (bulb number and weight) of Sternbergia lutea (L.) in annual growing period and bulblet formation capacities were investigated. Different - sized planting materials gave different growth rates, weight increases and bulblet formation capacity. Bulbs with circumference of 4-6 and 6-8 cm were shown to be more effective for bulb yield and bulblet formation capacity, respectively. © 2006 Asian Network for Scientific Information.
