蔬菜和菊苣种子试验(anmuricata L。)硝酸钾应用(KNO3)

蔬菜和菊苣种子试验(anmuricata L。)在硝酸钾(KNO3)应用后，本研究的目标是在硝酸钾(KNO3)应用后确定鳞茎的viability和vigor (muricata L.)。这项研究于2017年12月至2018年3月在萨姆大学MIPA学院的基础生物实验室进行。研究采用完整的随机设计(arral)进行三次重复研究。KNO3的浓度为四分之一，KNO3 (K0)， KNO3 1%(K1)， KNO3 2% (g3)和KNO3 3% (K3)。所观察到的参数是潜在的发芽、膨胀、vigor和vigor系数。研究表明，KNO3的应用程序在0.05测试水平上对沙囊种子的潜在影响(Sig= 0.00)。在播种21天后，对沙囊种子发芽的潜在观察结果为100%，而不是在33赫斯特时为100%。在第16天观察，K2和K3治疗的通病值是65%。锡尔球的观察结果显示，vigor的值为37.23,vigor的系数为24000。KNO3的礼物可以提高扁桃体和扁桃体的活力。关键词:番石榴籽、活动能力、维果、品性和果效测试(anmuricata L)。在使用硝酸钾(KNO3)后，将这一研究结果用于确定soursop种子的可行性和vigor (anmuricata L.)。该研究隶属于2017年12月至2018年3月间山姆皇后大学的基本生物学实验室。研究用了三个复制品进行了完全随机的设计。四年级四年级的学习集中是KNO3 0% (K0)， KNO3 1% (K1)， KNO3 2% (K2)和K3 3% (K3)。观测者观察到势函数、碰撞、维戈尔索引和维戈尔摄取。据预测，该应用程序在0.05级测试中对soursop seeds包括Sig = 0.00在内的潜在威胁有效。16日的K2和K3治疗，也就是6.65%。在33 HST，对soursop seeds的潜在威胁观测在21 HST达到100%，达到100%的速度控制。Vigor种子计数为37.23,Vigor coeffi培养为24。启动viability和vigor sourops seed。sourwoards: Soursop seed, viability, Vigor, KNO3
