摘要
对秋水仙素处理的油茶苗光合作用进行了初步研究。结果表明,0.1%秋水仙素处理苗与对照之间叶绿素含量存在显著差异;不同浓度处理油茶苗与对照之间Am ax和LSP均较低,其中只有0.1%处理苗Am ax和LSP的值均高于对照,分别达6.555CO2μmol/m2.s和271.4694μmol/m2.s,比对照分别增加3倍和1.7倍。处理苗和对照光补偿点(LCP)均较高,但0.3%处理苗LCP比对照LCP值低,为38.59073μmol/m2.s,0.1%和0.2%处理的均比对照高。从光合作用测定初步研究可得出:8号株叶绿素、净光合速率、光饱合点均比对照高,因此它可以作为优良品种选育的基础材料。
The oiltea camellia,which is the important arboreal oil tree species of the South of our country.We select 5 oiltea camellia seedling with prominent in shape and growth,which had been dealed with different colchicum density of 0(control),0.1、0.2 and 0.3 percent at the beginning of 2005,and carry on the photosynthetic indexes and chlorophyll contents.The result of the chlorophyll content menstruations show that: The chlorophyll content of tender leaf is prominent discrepancy between No.3(control) and No.1(de...
