6.The results showed that the height of plant, length of internode ,chlorophyll content and the leaf tissue structure loose ratio ( SR ) increased, but chlorophyll a/chlorophyll b, thickness of leaf, palisade tissue and spongy tissue, the tissue structure tense ratio ( CTR ) decreased.
植株增高、节间增长、叶绿素含量增加、叶绿素a/叶绿素b降低、叶片及栅栏组织和海绵组织厚度降低 ,叶片组织结构紧密度 (CTR)降低、叶片组织结构疏松度 (SR)增加 .
7.The results indicate that the chlorogenic acid content has obvious negative correlation with the weight of alabastrum of Flos Lonicerae picked in different areas of Pingyi county, Shangdong province. But the correlation with the concentrations of soluble sugars, polysaccharides, total sugars, chlorophyll a, chlorophyll b, total chlorophyll, N, P, K and total N/P/K content is not evident.
结果发现，平邑县不同乡镇村落所产金银花药材的绿原酸含量与花蕾重量之间具有明显的负相关性，而与可溶性糖、粗多糖、总糖、叶绿素a、叶绿素b、总叶绿素、氮、磷、钾、总氮磷钾等成份含量之间的相关性不明显；
8.The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b) in leaves of C. cajan had a peak in August and then declined while for M.fortunei,besides a peak in August,there was another peak in October.
木豆的叶绿素a/b的季节变化呈递减趋势,相反,十大功劳呈上升趋势。
9.The results showed that: 1 ) the changes of DGW resulted in the significant changes of net photosynthetic r ate (Pn), the transpiration rate (E), stomatal conductance (Gs), lea f contents o f chlorophyll a (Chl a), chlorophyll b (Chl b) and the total chlorophyll (Chl a + Chl b), the ratio of Chl a and Chl b (Chl a/Chl b), the quantum yield efficien cy and the CO 2 carboxylation efficiency;
