| 摘 要： | 以珍稀濒危植物张氏红山茶为材料,对其花发育形态及分化过程中生理指标动态变化进行了研究.采用定株调查的方法,通过观察、统计、解剖等确定张氏红山茶盛花期花芽着生位置并划分5个发育阶段,以分光光度法测定了5个发育阶段可溶性糖、可溶性蛋白和核酸含量等的动态变化.结果表明:盛花期花芽着生位置主要在枝条顶端,占70.0％；花芽和叶...

| Abstract: | The objective of the present investigation is to observe the effects of different Al3+ concentration(100,500,800,2 000 mg/L) along with different duration times(10,20,30 d) on growth characteristics and biomass allocation of the invasive plant P.virginica.The results showed that 100 mg/L of Al3+ had little effect on the growth of P.virginica.Under 2 000 mg/L of Al3+,both leaf areas and leaf numbers of P.virginica decreased.Spike number of P.virginica was promoted under 2 000 mg/L Al3+ stress for a short tre... |
