杨树优良无性系1年生扦插苗的光合生理特性

Research of poplars annual cottage seedlings excellent clones' photosynthetic physiological characteristic

以杨树2号、3号、s3236、s3804、t20这5个优良无性系1年生扦插苗为试验材料,测定其光合生理指标,旨在为江西省及相似地区杨树优良无性系选择和苗木培育提供依据。结果表明,光合生理特性测定的结果与实际的生长量基本一致,但并非完全吻合。从实际生长量分析,3号无性系的生长量较突出。从光合生理特性分析,s3236各个指标均较显著。

Take No.2, No.3, No.s3236, No.s3804 and No.t20 the 5 poplars annual cutting of excellent clones for testing materials, determined its photosynthetic physiological indexes, intending for select the superior clones of poplar in Jiangxi province and similar area and provide a basis for the cultivation of seedlings. The result shows that determinations of photosynthetic physiological characteristics are basically the same as the amount of actual growth, but not exactly. Analysis of ac-tual growth, No.3′s growth is more prominent. Analysis on photosynthetic physiological characteristics, No.s3236′s indicators are more prominent.
