绣球抗旱性综合评价及指标体系构建
|
摘要
采用盆栽持续干旱处理,测定5个耐旱能力不同的绣球品种生根苗25项生理生化指标,研究各品种绣球的抗旱性强弱,构建绣球品种抗旱性评价体系.结果表明:干旱胁迫20d后,绣球的比叶质量、细胞膜透性、丙二醛含量、超氧化物歧化酶活性、可溶性糖含量、脯氨酸含量、胞间CO_2浓度和非光化学猝灭系数均显著升高,而叶片相对含水量、净光合速率、气孔导度、蒸腾速率、光系统Ⅱ实际光量子产量和电子传递速率均显著降低.主成分分析将25项生理生化指标转化为3个互相独立的综合指标(累计贡献率达87.1%),主成分1主要反映光合、荧光等信息,主成分2主要反映植株活力等信息,主成分3主要反映膜系统及渗透调节系统等信息.聚类分析将5个绣球品种划分为3个类型:拉维布兰和塔贝为耐旱型品种,你我的浪漫为中间型品种,无尽夏新娘和银边为不耐旱型品种.根据绣球品种抗旱性综合评价值D,5个品种的抗旱性排序为拉维布兰>塔贝>你我的浪漫>无尽夏新娘>银边.细胞膜透性、过氧化物酶活性、可溶性蛋白含量和电子传递速率4个指标对绣球抗旱性有显著影响,可简化绣球抗旱性鉴定工作.
With the continuous drought stress treatment to five Hydrangea macrophylla varieties of different abilities of drought resistance,twenty-five physiological-biochemical indices were measured. We evaluated the drought resistance of different varieties and established the mathematic model. The results showed that leaf mass per area,cell membrane permeability( CMP),the content of malonaldehyde( MDA),the activity of superoxide dismutase( SOD),soluble sugar content,proline content,intercellular carbon dioxide and non-photochemical quenching coefficient were significantly increased under drought stress for twenty days. In contrast,relative water content,net photosynthetic rate,stomatal conductance,transpiration rate,actual photochemical efficiency of PSⅡ and electron transport rate( ETR) were significantly decreased. The principal component analysis classified those indices into three independent comprehensive indices( accumulative contribution of 87.1%). The principal component 1 mainly reflected the information of photosynthetic and fluorescence. The principal component 2 mainly reflected the information of plant vigor. The principal component 3 mainly reflected the information of membrane system and osmotic adjust system.Five H. macrophylla varieties were divided into three categories by clustering analysis: droughttolerant type( including H. macrophylla ‘Lavblaa') and H. macrophylla ‘Taube'),intermediate type( H. macrophylla ‘You and me romance'),and drought-intolerant type( including H. macrophylla cv. Endless summer bride and H. macrophylla ‘Tricolor'). Comprehensive evaluation of drought resis-tance( D value) showed that the ability of drought resistance decreased in order of H.macrophylla ‘Lavblaa'> H. macrophylla ‘Taube'> H. macrophylla ‘You and me romance'> H.macrophylla cv. Endless summer bride > H. macrophylla ‘Tricolor'. Four influential indices for drought resis-tance including CMP,the activity of peroxidase( POD),soluble protein contents( SP) and ETR was screened by stepwise regression analysis,which could be used for the rapid identification of drought resistance of H. macrophylla.
