It is necessary to increase the rates of initial growth of pastures for use during the better planting period. Thus, two experiments were used to evaluate the effect of plant growth regulator (PGR; auxins, gibberellins and cytokinins) in seeds types (coated with polymer coating fungicide and conventional method) and nitrogen fertilization methods in Brachiaria decumbens cv. Basilisk on the germination, growth, development and physiological composition. From the regression estimates, lower levels of PGR (10.3; 12.8; 8.85 and 9.57 ml/kg for germination percentage, germination speed index, leaf and pseudostem, respectively) were recommended in coated seeds when compared to conventional method (untreated seeds, with polymer coating and fungicide). Leaf and pseudostem mass production had a significant interaction effect between seed type and the use of growth regulator. Coated seeds (with fungicide and polymers after scarification) had greater performance with absence or at lower levels (8.85 and 9.57 ml/kg seed) of growth regulators. This was not observed for conventional seeds, the higher doses (15.5 and 18.1 ml/kg) presented higher development for the same characteristics. In second experiment, rates of photoassimilate were increased by soil fertilization and use of PGRs. No influence of foliar fertilization was observed when used exclusively, but N‐fertilization multiple and soil promotes an increase in chlorophyll content and mass yield, respectively. The use of exogenous hormonal compounds acts on the organogenesis of plant tissues and increases the formation of plant tissues and acts in the promotion of germination and development of structures, making it a key tool in pasture establishment.

植物生长调节剂和土壤肥料改善了臂状臂菜的产量和生育期

有必要提高草场的初期生长速度，以便在更好的播种期使用。因此，使用两个实验评估植物生长调节剂（PGR；植物生长素，赤霉素和细胞分裂素）对Bracharia decumbens种子类型（包被有聚合物包衣杀菌剂和常规方法）和氮肥施用方法的影响。简历。蛇怪在发芽，生长，发育和生理成分上。根据回归估计，与传统方法（未经处理的种子，使用聚合物）相比，建议包衣种子的PGR水平较低（发芽率，发芽速度指数，叶和假茎分别为10.3、12.8、8.85和9.57 ml / kg）涂料和杀菌剂）。叶片和假茎的大量生产在种子类型和生长调节剂的使用之间具有显着的相互作用。在没有或没有较低水平的生长调节剂的情况下，包衣的种子（划痕后含有杀菌剂和聚合物）的性能更高。对于常规种子未观察到这一点，对于相同的特性，较高的剂量（15.5和18.1 ml / kg）表现出较高的发育。在第二个实验中 施肥和使用植物遗传资源提高了光同化率。当单独使用时，没有观察到叶面施肥的影响，但是氮肥的施肥倍数和土壤分别促进叶绿素含量和产量的增加。外源激素化合物的使用对植物组织的器官发生起作用，并增加植物组织的形成，并在促进萌发和结构发展中起作用，使其成为牧场建立的关键工具。
