The effects of methyl 1-(3, 3-dimenthyl-2-oxobutyl)-1H-1, 2, 4-triazole-3-carboxylate (CGR(3)) and 1-(3,3-dimethyl-2-oxobutyl)-1H-1, 2, 4-triazole-3-carboxylic acid (CGR(3-1)), as two new plant growth regulators, on photosynthetic characteristics and mung bean yield were investigated in this study. Both regulators improved the net photosynthetic rate (P N ), stomatal conductance (gs), intercellular CO2 concentration (Ci) and transpiration rate (E); CGR(3-1) had a larger impact than CGR(3). In terms of photosynthetic efficiency, CGR(3-1) showed higher effectiveness. Considering photosynthetic pigments, the two regulators enhanced the contents of chlorophyll a, chlorophyll b, chlorophyll (a+b) and carotenoid. The application of CGR(3-1) (CGR(3)) significantly increased (decreased) the contents of soluble sugar and starch. The results indicated that CGR(3-1) was more effective in improving the photosynthetic characteristics and yield of mung bean and can be a widely adopted strategy for producers.
为促进磷肥推广应用及提高大豆产量,以黑河43为试验材料,于2017年在黑龙江省九三管理局鹤山农场试验基地进行施磷对大豆农艺性状、光合特性及产量影响的研究.结果表明:鼓粒期D1[富硫磷二铵(581.56 g·m-2)+尿素(78.17 g·m-2)+氯化钾(225.11 g·m-2),总养分(N+P2 O5)≥54.0% 、14%-40%-0%,其中,总S≥10%]和D2[硝基黄腐酸二铵(553.86 g·m-2)+尿素(75.75 g·m-2)+氯化钾(225.11 g·m-2),总养分(N+P2 O5)≥57.0% 、15%-42%-0%,其中,黄腐酸≥2%]处理的大豆株高、茎粗、地上部单株干物质积累量均高于CK,其中以D2处理较好.在鼓粒期,D2处理的大豆叶片SPAD值、净光合速率和气孔导度均显著高于CK.在鼓粒期,D2处理通过提高大豆叶片叶绿素含量和净光合速率,调控了大豆叶片同化物质的积累,从而提高了大豆产量.
We synthesized nine novel triazole-compounds and investigated their plant growth regulatory activity. Compound CGR3, with methoxyacyl on 3-position of triazole ring, showed better activity, promoting root length not only for mungbean, but also for wheat. Additionally, CGR3 changed the level of endogenous hormones in mungbean roots, the most obvious effect was the increase of IAA, being 4.9 times greater than that of the control at the 96th hour after treatment. Among the synthesized new 1,2,4-triazol derivatives, CGR3 could be applied as a new agrochemical, functioning as a root growth stimulant, which promotes primary root length, influences the levels of endogenous hormones(IAA, ABA and GA3) to play an important role in controlling the primary root development.

The title compound 1-(3-amino-[1,2,4]triazol-1-yl)-3,3-dimethyl-butan-2-one (3) was synthesized by Hofmann-alkylation reaction of 1- chloro-3,3-dimethyl- butan-2-one (1) and 1H-[1,2,4] triazol-3-ylamine (2) with equal amount of K2CO3 as acid acceptor. The structure of compound 3 was characterized by H-1 NMR, C-13 NMR, HRMS and single-crystal X-ray diffraction. The compound crystallizes in the monoclinic system, space group P2(1)/n with a = 5.7227(8), b = 27.924(4), c = 6.2282(7) angstrom, beta = 101.892(11)degrees, V = 973.9(2) angstrom(3), Z = 4, T = 180.00(10) K, mu(MoKa) = 0.087 mm(-1), Dc = 1.243 g/cm(3), 3832 reflections measured (3.648 <=theta <= 26.022 degrees), 1916 unique reflections (R-int = 0.0359, R-sigma = 0.0572) used in all calculations. The final R = 0.0557 (I > 2 sigma(I)) and wR = 0.1276 (all data). Bioassay showed that 3 displayed excellent activity as plant growth regulator with inducing lateral root formation and enhancing primary root elongation at 0.27 mmol/L (50 ppm) in soybeen (He Feng-50). Good water solubility was found with 50 mg in 1 mL of water. Therefore, application of 3 in agriculture is more environmentally friendly due to cosolvent- free condition, and results in improved abiotic-stress tolerance by affecting the root growth. And furthermore, it can be used as a precursor to investigate the function of regulating plant root growth.
The effects of foliar spraying uniconazole (S3307) and kinetin (KT) on carbon metabolism of maize leaves and yield were studied in order to provide theoretical foundation for maize production.In the filed experiment,using ‘Demeiya 1'and ‘Demeiya 2’ as test materials,S3307 and KT was sprayed at 7 leaves expansion stage,water was sprayed as control.The effects on the carbon metabolism of maize leaves and the yield were studied.The results showed that S3307 and KT increased panicle weight,grain weight,number of rows,kernels per row and single grain weight,and then raised the grain yield.The regulating effect of KT treatment on the yield of ‘ Demeiya 1’ was better than that of S3307 and the regulating effect of S3307 treatment on the yield of ‘ Demeiya 2’ was better than that of KT.After 21-30 days of spraying regulators,the two regulators decreased the starch content and starch amylase activity.The starch content and amylase activity of ‘Demeiya 1’ was decreased by the range of 0.16%-31.10% and 7.58%-45.83%,respectively.The starch content and amylase activity of ‘Demeiya 2’ was decreased by the range of 2.68%-42.01% and 3.97%-39.82%,respectively.After 21 days of spraying regulators,the order of sucrose and soluble sugar contents in leaves of the two varieties was KT>S3307>CK.Compared with the control,the sucrose and soluble sugar content of ‘Demeiya1’ increased by 84.64%,31.28%,67.38% and 52.74% by foliar spraying KT and S3307,respectively;the sucrose and soluble sugar content of‘Demeiya2’ increased by 14.21%,3.92%,49.34% and 37.50% by foliar spraying KT and S3307,respectively.S3307 and KT could significantly enhance physiological activities and delay the senescence of maize leaves during middle-late growth stages.Thereby,they were effective to increase the yield of maize.
