中原牡丹和西北牡丹花粉活力、生理生化及形态特征的比较研究
Comparative Study on Pollen Viability,Physiological and Biochemical Indices,and Morphological Char-acteristics of Central Plains Peony and Northwest Peony
摘要
Abstract
To investigate the differences in pollen biological characteristics between Central Plains peony cultivars and Northwest pe-ony cultivars,pollen from six representative cultivars from each group were selected as the experimental material.Pollen viability,physiological and biochemical indices,and microscopic morphological characteristics were measured,and the differences and internal relationships among these indices were systematically compared.The results showed that pollen viability varied significantly among different peony cultivars,with the overall pollen viability of the Northwest cultivar group being significantly lower than that of the Cen-tral Plains cultivar group.Regarding physiological and biochemical indices,'Luhehong'and'Guifuren'exhibited relatively high solu-ble protein content and SOD activity,'Zibanbai'had the highest malondialdehyde content,'Mengxiang'presented the highest POD ac-tivity,and'Yeguangbei'showed the highest CAT activity.Pollen grains of Central Plains peony cultivars were generally larger and more uniform in morphology,whereas Northwest peony cultivars demonstrated greater morphological diversity.In conclusion,Central Plains peony cultivars display superior biological characteristics in terms of pollen viability,physiological and biochemical indices,and morphological characteristics,indicating their greater potential as male parents in breeding programs.关键词
