在大田栽培条件下,大豆‘垦农4号’于开花始期叶面喷施植物生长物质2-N,N-二乙氨基乙基己酸酯(DTA)、氯化胆碱(CC)和SOD模拟物(SODM),并比较不同植物生长物质影响大豆叶片、叶柄和茎的解剖结构。结果表明,喷施植物生长物质后30d,叶中栅栏组织厚度及栅海比均增加;喷施SODM、DTA的叶中主脉维管束横截面积和木质部导管数目增加,CC对主脉维管束横截面积和木质部导管数目的影响不明显;喷施3种植物生长物质的叶柄表皮细胞厚度、叶柄维管束横截面积和导管数量增加,茎部薄壁组织、韧皮部和木质部厚度增加,茎的直径也增加。
Under field cultivation, Soybean “Kenong No.4” was sprayed with 2, N, N-diethylaminoethylhexanoate (DTA), choline chloride (CC) and SOD (SODM), and compared the different plant growth substances affect the anatomy of soybean leaves, petioles and stems. The results showed that the thickness of palisade and the ratio of grid to fence were increased 30 days after the spraying of plant growth substances. The cross-sectional area of vascular bundles and the number of xylem in the main veins in leaves were increased after spraying SODM and DTA. Cross-sectional area and the number of xylem catheters were not significant. The thickness of petiole epidermis cells, the cross-sectional area of petiole vascular bundles and the number of catheters increased with the growth of three plant growth substances. The thickness of stem parenchyma, phloem and xylem increased, Diameter also increased.
