| 摘 要： | 采用SPAD-502叶绿素计、LI-6400型便携式光合分析仪与分光光度法分别对种子源于江西遂川(MPS)和福建建瓯(MPJ)的3年生刨花楠与江西上犹(MLG)的3年生华东润楠苗木叶片的SPAD值、净光合速率(Pn)和叶绿素a+b含量(Ct) 进行了测定.结果表明：3种苗木叶片叶绿素含量存在显著差异，其SPAD值、叶绿素a+b、叶绿素a与叶绿素b含量均为MPS-1.受叶肉组织发育成熟程度影响，当年生新叶的叶绿素含量低于2年生叶片.MPS与MPJ刨花楠同一叶龄叶片不同冠层间的Ct次序为上冠层<中冠层<下冠层，华东润楠则为上冠层<下冠层<中冠层.同一叶片不同观测部位间的SPAD值次序为尖端<中部<基部.叶片的SPAD值与叶绿素a+b含量呈显著正相关，与Pn虽存在正相关，但不显著.

| Abstract: | By using SPAD-502 chlorophyll meter, LI-6400 portable photosynthesis system, and spectrophotometer, the leaf SPAD value, net photosynthetic rate ( Pn), and chlorophyll (a+b) content (Ct) of 3-year-old Machilus pauhoi and M. leptophylla seedlings were measured, and the relationships of SPAD value with Pn and Ct were analyzed. The M. pauhoi seedlings were grown from the seeds originated from Suichuan County of Jiangxi Province and Ji an’ou County of Fujian Province, named as MPS and MPJ, respectively; while the M. leptophylla seedlings were grown from the seeds originated from Shangyou County of Jiangxi Province, named as MLG. There were significant differences in the mean chlorophyll content of MPS, MPJ, and MLG. The SPAD value and the conten ts of chlorophyll (a+b) (Ct), chlorophyll a (Ca) and chlorophyll b (Cb) we re in the order of MPS
