有机肥的降解物香草醛,可缩短苹果新梢长度和节间长度,但不降低叶面积和叶片厚度。叶绿素含量、可溶性糖含量显著上升,10~(-6)mol·1~(-1)处理显著或极显著提高叶片氨基酸、核酸的含量,10~(-4)mol·1~(-1)处理降低二者含量。喷施10~(-6)、10~(-8)mol·1~(-1)香草醛极显著提高苹果叶片K~+浓度,所有处理叶片中 Ca~(2+)累积量显著下降。10mg·1~(-1)香草醛可以延缓离体苹果子房 CAT 酶活性和 MDA 含量上升,对维持细胞活性有良好作用。10~(-4)mol·1~(-1)香草醛喷施可以显著降低六月落果,10~(-60、10~(-8)mol·1~(-1)处理可显著减少采前落果。10~(-6)mol·1~(-1)香草醛显著提高苹果产量和单果重,可溶性糖、还原糖、非还原糖及维生素 C 含量都有显著提高,果实着色度也有显著改善,但果实硬度降低。
Vanillin, a biodegradable organic fertilizer, shortens shoot tip length and internode length but does not reduce leaf area and leaf thickness. The content of chlorophyll and soluble sugar increased significantly, and the content of amino acid and nucleic acid in leaves increased significantly with 10 -6 mol • -1 -1 treatment, Decrease the content of both treatment. Spraying 10 ~ (-6) and 10 ~ (-8) mol · 1 ~ (-1) vanillin significantly increased the K ~ + concentration of apple leaves, and the accumulation of Ca ~ (2+) in all leaves significantly decreased. Vanillin at 10 mg · 1 -1 could delay CAT activity and MDA content in isolated ovary of offsprings, and had a good effect on maintaining cell viability. 10 ~ (-4) mol · -1 ~ -1 vanillin could significantly reduce fruit drop in June, while 10 ~ (-60,10 ~ (-8) mol · -1 ~ The results showed that vanillin (10 ~ (-6) mol · -1 -1) significantly increased the yield of apple and the weight of single fruit, the contents of soluble sugar, reducing sugar, non-reducing sugar and vitamin C were significantly increased, Improve, but fruit firmness decreases.
