中文摘要:
      对11份甘蔗种质(ROC22号、 YT93–159、 DZ09–78、YZ12–1202、YZ11–1122、YZ05–51、YZ11–2629、YZ12–1252、YZ12–1185、YZ12–1301、YZ11–1204)中的铁(Fe)、锌(Zn)、硒(Se)进行检测,通过方差和广义遗传力分析发现,甘蔗蔗汁中Fe、Zn和Se平均含量差异较大,且变异广泛,变异系数为21.89%~41.45%;Fe、Zn和Se元素广义遗传力较高,分别达到0.94、0.99和0.94。基于微量元素含量差异对甘蔗种质进行聚类分析发现,11份甘蔗种质可以聚为3类,分别为富Fe种质、富Zn种质和普通种质,其中,富Fe种质包括ROC22号、YZ12–1301和YZ12–1252,蔗汁中的Fe含量显著高于其他种质,平均含量达5.30 mg/kg;富Zn种质包括YZ05–51、YT93–159和YZ11–118,蔗汁中的Zn含量达到3.00 mg/kg;第3类为普通种质,微量元素含量普遍较低。对聚类结果的逐步判别分析发现,各类种质被正确分类的概率均为100%,聚类结果可靠,各个种质均被正确分类。
英文摘要:
      We detected the concentration of ron (Fe), zinc (Zn), selenium (Se) among 11 sugarcane germplasms(ROC22, YT93-159, DZ09-78, YZ12-1202, YZ11-1122, YZ05-51, YZ11-2629, YZ12-1252, YZ12-1185, YZ12-1301 and YZ11-1204) and performed statics analysis of the resulted data. The results of variance and generalized heritability analysis showed that the average contents of Fe, Zn and Se among sugarcane germplasms were significantly different. The coefficient of variation was 21.89%-41.45% and the broad sense heritability of Fe, Zn and Se was high, at 0.94, 0.99 and 0.94 respectively. In addition, cluster analysis of 11 sugarcane germplasms based on the difference of trace element content showed that the studied objects could be grouped into three groups, Fe-rich germplasm, Zn-rich germplasm and common germplasm. Among them, the Fe-rich germplasms mainly include ROC22, YZ12-1301 and YZ12-1252, and the Fe content in sugarcane juice is significantly higher than other germplasms, with an average of 5.30 mg/kg. The Zn-rich germplasms mainly include YZ05-51, YT93-159 and YZ11-118, and the average zinc content in sugarcane juice was as high as 3.00 mg/kg. The third type was common germplasm, and the content of trace elements was generally low. Through stepwise discriminant analysis of clustering results, it showed that the probability of correct classification of all kinds of germplasms was 100% and the clustering results were well verified.
