The improvement of gogo rice production in dryland is constrained by its extraordinary height, which leads to falling, and its long lifespan. The shorter gogo rice plant can be obtained through growth inhibition using paclobutrazol. Gogo rice plant var. Inpago Unsoed 1 was used during the study. An experimental study was performed using factorial completely randomized design. The main factor was four paclobutrazol concentrations (0,100, 200, and 300 ppm). The sub-main factor was paclobutrazol application time after planting (three, four, and five weeks). The results showed that the interaction between paclobutrazol concentration and application time was highly significantly affecting plant height. The most appropriate treatment resulting in optimum plant height was the combination of 100 ppm paclobutrazol applied four weeks after planting. Interaction between paclobutrazol concentration and application time also significantly affect stem diameter, leaf width, and stomata number in the lower leaf epidermis. However, there was no significant effect of paclobutrazol observed on stomata size. The significant result of the combination of paclobutrazol concentration and the application time was also supporting tissue thickness. The thickest tissue was obtained by 300 ppm of paclobutrazol applied five weeks after plantation.

旱地gogo水稻产量的提高受限于其非常高的高度，导致下降，并且其寿命长。可以通过使用多效唑抑制生长来获得较短的gogo水稻植株。Gogo 水稻植物 var. 在研究期间使用 Inpago Unsoed 1。使用因子完全随机设计进行实验研究。主要因素是四种多效唑浓度（0,100、200 和 300 ppm）。次主要因素是种植后多效唑的施用时间（三、四和五周）。结果表明，多效唑浓度与施用时间的交互作用对株高有极显着影响。产生最佳株高的最合适的处理是在种植后 4 周施用 100 ppm 多效唑的组合。多效唑浓度和施用时间之间的相互作用也显着影响下叶表皮的茎粗、叶宽和气孔数。然而，没有观察到多效唑对气孔大小的显着影响。多效唑浓度和应用时间相结合的显着结果也支持组织厚度。种植后五周施用 300 ppm 的多效唑可获得最厚的组织。多效唑浓度和应用时间相结合的显着结果也支持组织厚度。种植后五周施用 300 ppm 的多效唑可获得最厚的组织。多效唑浓度和应用时间相结合的显着结果也支持组织厚度。种植后五周施用 300 ppm 的多效唑可获得最厚的组织。
