温室连续栽培对藏红花小球茎繁育的促进作用及对藏红花质量的影响
Effect of Consecutive Cultivation Under the Greenhouse Condition on Small Corm Propagation and Quality of Crocus sativus
摘要
Abstract
Objective:To study the promoting effect of consecutive cultivation under the greenhouse condition on the propagation of small corms,and study the quality of Crocus sativus.Methods:The temperature in winter was raised by using the greenhouse in order to provide a more optimal temperature for corm growth of Crocus sativus.The multiplication growth period was prolonged by early planting,and increased the reproduction rate of large progeny corms.Multiplication rates of progeny corms and the proportion of large progeny corms were used as the index to study the effect of planting time,seed corm weight,growing years and propagation methods of small corms.The flower number,stigma weight,and content of effective component in filament were used as the index to optimize the way of corm propagation and cultivating flowers.Resuhs:The small corms could be propagated into large corms which cultivated under the greenhouse condition,and the cue ball weight was greater when planted in the earlier planting time,and the rate which produced large flowering bulbs was larger.The propagation rate of two subsequent years was 2.9 times larger than that of one year,and the progeny corms weight above 15 g was 2.6 times larger than that of one year.There were no statistically differences on the number of flowers and silk weight between the corms propagated under the greenhouse and under open field in" two stage cultivation",and there was no significant differences in the content of total crocins,picrocrocin and safranal.The content of picrocrocin and total crocins from Crocus sativus cultivated indoors were sepatately higher by 65.0% and 27.8% than outdoors,respectively.Conclusion:Continuous cultivation under the greenhouse has promoting effect on the propagation of small corms,but the quality of Crocus sativus cultivated in open field is poorer.The present study indicates that small corms should be graded after two year management cycle under the greenhouse condition.Small corms heavier than 15 g should be cultivated through "two stage cultivation" to produce high quality Crocus sativus stigma,while small corms lighter than 15 g should be early planted and consecutively lasted two years to improve the corm propagation rate and produce more larger corms.关键词
