科学研究

  主要从事设施瓜类作物嫁接耐逆境、嫁接调控瓜类作物吸收代谢方面的生理和分子机制研究。代表性科研成果如下图所示：

（1）嫁接功效与嫁接过程本身无关，主要取决于其砧木根系的基因型（Zhen et al., 2010）。

Figure 1 Salt injury index and plant growth of the grafted cucumber seedlings under 0 mmol L)1 and 100 mmol L)1 NaCl stress. Leaf damage score: level 1 (0% area of yellow leaf), level 2 (1–25% area of yellow leaf), level 3 (26–50% area of yellow leaf), level 4 (51–75% area of yellow leaf) and level 5 (76–100% area of yellow leaf). Values are the mean ± standard error (n = 3). Bars with the same letters indicate no significant difference according to Duncan’s multiple range test (P < 0.05). J1 ⁄C, Jinyu No. 1 grafted onto Chaojiquanwang; J1 ⁄ F, Jinyu No. 1 grafted onto Figleaf Gourd; J2 ⁄ C, Jinchun No. 2 grafted onto Chaojiquanwang; J2 ⁄ F, Jinchun No. 2 grafted onto Figleaf Gourd.

（2）砧木对嫁接黄瓜植株光合同化和光合机构保护中发挥重要作用（Zhen et al., 2011）。

Figure 2 Transmission electron microscopy (TEM) of chloroplast ultrastructure in cucumber seedling leaves. a–c Self-grafted cucumber seedlings treated by 0, 50, and 100 mM NaCl, respectively. d–f Rootstock-grafted cucumber seedlings treated by 0, 50, and 100 mM NaCl, respectively. G granum thylakoids, S stroma thylakoids, P plastoglobulus, SG starch grain. Bars 2 lm.      

（3）外援喷施ALA能增强黄瓜叶片中活性氧清除能力，从而缓解NaCl胁迫对植株生长和光合作用的伤害（Zhen et al., 2012）。

Table 1 Effects of exogenous ALA and NaCl on H2O2 content; activities of SOD, CAT, APX, GR, MDHAR and DHAR; relative transcript expressions of CAT, cAPX, and GR; and the AsA and GSH contents in cucumber roots and leaves. Means ± SE, n = 3. Values marked with the same letter are not significantly different at P ≤ 0.05 (DMRT test). CK - plants only sprayed with the de-ionized water containing 0.01 % surfactant; NaCl, plants exposed to only 75 mM NaCl stress; NaCl+ALA, plants exposed to 75 mM NaCl stress and sprayed with 50 mg dm^-3 ALA.

（4）外援喷施GABA对植物NO₃^-吸收利用方面具有重要的正调控作用（甄爱等，2016；Zhen et al., 2018）。

Figure 3 Effects of exogenous GABA on NO₃^--N and NH₄⁺-N contents in muskmelon seedlings roots and leaves under Ca(NO₃)₂ stress. Values are mean ± SE (n = 3). Different letters indicate significant differences among treatments at the P < 0.05 level. CK: untreated control plants; G: plants treated with GABA only; S: plants treated with Ca(NO₃)₂ stress only; SG: plants treated with Ca(NO₃)₂ stress and GABA. FW: fresh weight.

Table 2 Effects of exogenous GABA on the nitrogen assimilation enzyme and transaminase activities in muskmelon seedlings under Ca(NO₃)₂ stress.

Values are mean ± SE (n = 3). Different letters indicate significant differences among treatments at the P < 0.05 level. CK: untreated control plants; G: plants treated with GABA only; S: plants treated with Ca(NO₃)₂ stress only; SG: plants treated with Ca(NO₃)₂ stress and GABA.

*P < 0.05; **P < 0.01; ***P < 0.001; ns, not significant (n = 4). NO₃^--N, nitrate nitrogen; NH₄⁺-N, ammonium nitrogen; NR, nitrate reductase; GS, glutamate synthetase; GOGAT, glutamate amino transferase; GDH, glutamate dehydrogenase; GOT, glutamate oxaloacetate transaminase; GPT, glutamate pyruvate aminotransferase.
