摘要
牡丹,中国十大传统名花之一,具有"花中之王"的美誉,江南牡丹作为中国牡丹四大品种群之一,由于受到湿热气候的影响发展较慢,部分品种逐渐消失,选择适宜江南地区生长的牡丹品种具有重要意义。本文以9个中原地区引种牡丹品种为研究对象,研究了其在相同淹水胁迫下不同胁迫时间其细胞膜透性、叶绿素含量、抗坏血酸过氧化物酶(APX)、过氧化氢酶(CAT)的变化规律。结果表明:大部分品种细胞膜透性呈现先升高后降低的变化趋势,部分品种呈现先降低后升高后降低的变化趋势,叶绿素a、叶绿素b、类胡萝卜素均呈现逐渐下降的变化趋势,下降情况有所不同,APX酶活性随着处理时间的延长呈逐渐下降的趋势,大多数品种CAT酶活性随着处理时间的延长而逐渐下降,‘俊艳红'呈现先升高后降低的变化趋势。本研究将为耐涝牡丹品种筛选奠定理论基础。
Peony is one of the ten traditional famous flowers in China,has the reputation of "King of the Flowers".As one group of four Chinese peony cultivars,the peony of the Southern Yangtze River develop slowly because of the hot and humid climate,and some species are disappearing,so it is important to select the appropriate peony cultivars which can grow well in the Southern Yangtze River area.This article take nine peony cultivars which come from Shandong as study objects,The change low of the cell membrane permeability,chlorophyll content,ascorbate peroxidase(APX) and catalase(CAT) were studied when the cultivars under same waterlogging stress in different time.The results showed that the cell membrane permeability of most cultivars exhibit a trend of declined first and then ascended,some varieties showing a trend of ascended after the first declined,then declined again.Chlorophyll a,chlorophyll b,carotenoids showed a trend of gradual decline,the decline situation is different.APX activity showed a gradual decline trend with the extend of processing time,most cultivars' CAT activity declined gradually with the extend of processing time,and Junyanhong showed a trend of declined first and then ascended.This study will lay a theoretical foundation on waterlogging peony cultivar screening.
