以茶花Camellia 3 个主要品种群的15 个品种为材料, 利用生理生化测定及SPSS 统计分析对其耐热性进行了研究。结果表明:持续7 d 36 ~ 38 ℃的高温胁迫能够有效区分不同茶花品种耐热性;生理生化测定结果的系统聚类与主成分分析能够对不同茶花品种的耐热性进行有效评价。云南山茶Camellia reticalata 及其杂种品种群耐热性较差, 茶梅C .sasanqua 耐热性较强, 而红山茶C .japonica 品种群耐热性变化范围较大。茶花品种耐热性与花型相关性不大。图1 表4 参15 相似文献

The nutritional components and poisonous elements in flowers of Camellia chekiangoleosa, C. polydonta, C. semiserrata and C. azalea were studied. The results indicated that the soluble sugar content of the four Camellia flowers had no difference. The maximum protein content was 82.9 g·kg-1, detected in the flower of C. semiserrata. And the minimum protein content was 56.8 g·kg-1, found in C. azalea. Vitamin C and β-carotene contents in C. azalea and C. semiserrata were higher, and in C. polydonta and C. chekiangoleosa were lower. The total amino acid contents of the four Camellia were 68.41、67.26、50.77、66.87 g·kg-1 respectively, the essential amino acid contents were 33.86、32.70、27.21、33.79 g·kg-1 respectively, and the proportion of essential amino acid in total amino acid of the four Camellia were 49.50%, 48.62%, 53.59% and 50.53% respectively. The contents of Ca, Mn and Cu in C. chekiangoleosa were the highest. Zn and Se contents were the maximum and Ca was the minimum in C. polydonta. The contents of Fe and Se were the lowest in C. semiserrata. Fe content were the maximum and Mn, Zn and Cu the minimum in C. azalea. The trace element contents in the flower of the four Camellia species followed the order of Mn, Fe, Zn, Cu, Se, but the content of Fe was higher than that of Mn in C. azalea. The contents of Pb, Cd, As and Hg of the four Camellia flower were all lower than the permissible amount. 相似文献

为使产油真菌浅白隐球酵母的油脂更适合生物柴油的要求,利用根癌农杆菌介导的遗传转化方法,将植物SAD基因转入浅白隐球酵母中,并对影响转化效率的关键因子进行了优化。结果表明:利用农杆菌菌株AGL-1介导,农杆菌浓度为1×109个/mL,酵母浓度为酵母密度为1×107~2×107个/mL,在含有AS200μmol/L条件下共培养48h可获得较高的转化率。PCR检测表明,SAD基因已成功转入浅白隐球酵母中,证明了该转化系统对浅白隐球酵母遗传转化的可行性。 相似文献
