采用气相色谱-质量选择检测器对仙客来、紫仙客来及其种间杂种全花的顶空样品进行了分析。仙桃挥发物（2n = 2x = 48， AA或4x = 96， AAAA）主要由倍半萜类化合物组成，而仙桃挥发物（2n = 2x = 34， BB）主要由醇类、醛类和单萜类或芳香类酯类化合物组成。杂种（2n = 41， AB）、双二倍体（2n = 82， AABB）和倍半二倍体（2n = 58， ABB）挥发物的化学组成与紫癜C的挥发物非常相似。倍半二倍体（2n = 65， AAB）挥发物的化学组成与桃香薷挥发物相似。二倍体或四倍体仙桃的花具有木质或粉末状香味，而紫花仙桃的花具有玫瑰或风信子般的香味。杂种AB、两二倍体AABB和倍半二倍体ABB的花具有类似紫癜的香味，而倍半二倍体AAB的花具有类似桃香的香味。在此基础上，讨论了挥发性化合物的表达与基因组构成的关系。(C) 2002 Elsevier Science B.V.版权所有
Headspace samples collected from entire flowers of Cyclamen persicum, C purpurascens and their interspecific hybrids were analyzed using gas chromatograph coupled with mass selective detector. The chemical constitution of volatile compounds of C persicum (2n = 2x = 48, AA or 4x = 96, AAAA) was distinguished by sesquiterpene hydrocarbons, whereas that of volatile compounds of C purpurascens (2n = 2x = 34, BB) was distinguished by alcohols, aldehydes and esters of monoterpene or an aromatic class. The chemical constitution of volatile compounds in the hybrid (2n = 41, AB) the amphidiploid (2n = 82, AABB) and the sesquidiploid (2n = 58, ABB) closely resembled that of volatile compounds in C purpurascens. By contrast, the chemical constitution of volatile compounds in the sesquidiploid (2n = 65, AAB) resembled that of volatile compounds in C persicum. Flowers of diploid or tetraploid C. persicum had a woody or powdery fragrance, whereas those of C. purpurascens had a rose- or hyacinth-like fragrance. Flowers of the hybrid AB, the amphidiploid AABB and the sesquidiploid ABB had a fragrance resembling that of C. purpurascens, whereas those of the sesquidiploid AAB had a fragrance resembling that of C persicum. Based on the present analyses, the relationship between the expression of volatile compounds and genome constitution is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
