Abstract

The exogenous liquid introduction technology is an effective way to produce the value-added poplar wood with excellent pattern color. This technology was used to add the various concentrated active red dyeing solution (0.2%, 0.4% and 0.6%) into target trees of six-year-old 107 poplar (Populus ×euramericana cv. '74/76'). The photosynthetic gas exchange parameter and sap flow rate were measured by Li-6400 photosynthetic instrument and TDP stem flowmeter, respectively. We analyzed the relationship between photosynthetic parameters, sap flow rate and dye absorption, and the effects of exogenous dye solution on the photosynthetic physiology and sap flow characteristics. The results showed that exogenous dyeing solution significantly inhibited flow rate of poplar trunks. The 0.2% concentrated liquid was far less effective than others (0.4% and 0.6%). The net photosynthetic rate (Pn), stomatal conductance (gs) and transpiration rate (Tr) of poplars treated with different concentrated dyeing liquids were significantly lower than the control poplar. The intercellular carbon dioxide concentration (Ci) decreased first and then increased. The inhibitory effects of 0.4% and 0.2% concentrated dyeing solutions on photosynthesis were stronger than that of 0.6%. Dye absorption decreased with increasing dye concentration. The maximum liquid flow rate, Pn, gs and Tr were significantly negatively correlated with the dye content. The contents of chlorophyll (a+b), chlorophyll a and chlorophyll b in exogenous dyeing solution treatments were significantly lower than those of the control at the later stage. The concentration of dyeing solution and introduction time determined the amount of dye absorption. The dye solution 0.4%, which was introduced for three days, could ensure the appropriate dye absorption and reduce the inhibitory effect on the physiological activities of the poplar.

<AbstractText>外源染液导入技术是从花纹色泽角度提升杨树木材附加值较为有效的方法。以6年生107杨为试材,采用外源液体导入技术将不同浓度活性红染液(0.2%、0.4%和0.6%)导入树体内,利用Li-6400光合仪和热扩散式TDP茎流计分别测定其光合气体交换参数和树干液流速率,研究外源染液对107杨光合生理与液流特征的影响,并分析各光合参数、液流速率与染料染着量的关系。结果表明: 外源染液导入对107杨树干液流速率抑制作用显著,0.2%染液处理显著低于0.4%和0.6%染液处理;不同浓度染液处理107杨净光合速率(
<i>P</i>
<sub>n</sub>
)、气孔导度(
<i>g</i>
<sub>s</sub>
)、蒸腾速率(
<i>T</i>
<sub>r</sub>
)显著低于对照,胞间CO
<sub>2</sub>
浓度(
<i>C</i>
<sub>i</sub>
)呈先下降后上升的趋势,0.4%和0.2%染液对各光合参数抑制作用高于0.6%染液;染着量随染液浓度的升高而下降,最大液流速率、
<i>P</i>
<sub>n</sub>
<i>g</i>
<sub>s</sub>
<i>T</i>
<sub>r</sub>
均与染料染着量呈显著负相关。处理后期107杨叶绿素(a+b)含量、叶绿素a和叶绿素b含量均显著低于对照。染液浓度和染液导入时间决定染料染着量,向树体导入0.4%浓度染液3 d,能在保证适当染着量的基础上减缓对107杨生理活动的抑制作用。.</AbstractText>
