不同品种花烛鲜切花保鲜期比较

Comparison of Fresh-Keeping Age of Different Cultivars of Anthurium Cut Flowers

选取了 12个具有代表性的花烛品种 ,进行瓶插保鲜试验 ,比较各品种间保鲜期的差异 .结果表明 :12个品种中热带、梦幻、紫色快车、罗沙和卡罗等 5个品种保鲜期短 ,其瓶插保鲜期在 10 d左右 ;绿苹果、卡丽、白兰地、苏雷、元老、总统和白雪 7个品种保鲜期长 ,其瓶插保鲜期在 17～ 33d之间 .同时结合感观审评结果 ,提出了花烛鲜切花存在易败品系和非易败品系 ,而非易败品系佛焰苞多为绿色 ,易败品系佛焰苞多为红色 .

Twelve cultivars of Anthurium cut flowers are chosen as the experimental samples to study their fresh-keeping deviation. The results of the studies prove that5 cultivars,Tropical, Fantasia, Rapido, Rosa and Casino,are easy to decline,with about 10 days of fresh-keeping,while the other 7 cultivars,Pistache, Carre,Cognac,Sonate,Senator,President and Pierrot,are opposite,with 17 to 33 days of fresh keeping.So,they can be divided into easily declining cultivars and non-easily declining cultivars according to their fresh-keeping age. The above situation is the main reason that causes nonuniform aging and decaying of the cut flowers.The most easily declining cultivars which are the main ones of production hold red phyllaries,while most non-easily declining cultivars hold green phyllaries.
