Abstract

The Research about the effects of extract from the invasive plant leaves of Mikania micrantha Kunth. and non-invasive plant leaves of Cosmos sulphureus Cav. on the germination of corn (Zea mays L.) has been conducted in July 2016 in Plant Physiology and Tissue Culture Laboratory, Biology Department, Mathematics and Natural Science Faculty, Andalas University, Padang. The aim of this research was to compare the effect of extract from the leaves of plants M. micrantha and C. sulphureus with several concentrations on the germination of corn. The research used experimental method with Completely Randomized Design (CRD) on Nested, 9 treatments and 4 replications. The treatments were factor A (type of plants, a1= Mikania micrantha and a2= Cosmos sulphureus) and factor B (leaf extract concentration, b0= 0%, b1= 20%, b= 40%, b3= 60%, b4= 80%). The results showed that the extract of the leaves from M. micrantha affected to reduced the fresh weight plants at concentration of 20%, where as in leaf extract of C. sulphureus affected to reduced the fresh weight plants at concentration of 40%.

Mikania Mikrantha Kunth植物薄片提取器。（Invasive）和Cosmos sulfureus Cav。（【非侵入性】）面临着巨大的增长（Zea mays L.）

薇甘菊入侵植物叶片提取物的药效研究。和Cosmos sulfureus Cav的非侵入性植物叶片。于2016年7月在巴东安达拉斯大学数学与自然科学学院生物系植物生理学与组织培养实验室对玉米（Zea mays L.）的发芽进行了研究。本研究的目的是比较不同浓度的薇甘菊和硫磺草叶片提取物对玉米发芽的影响。本研究采用完全随机设计（CRD）的实验方法对嵌套、9个处理和4个重复进行研究。处理为因子A（植物类型，a1=薇甘菊，a2=硫菊）和因子B（叶提取物浓度，b0=0%，b1=20%，B=40%，b3=60%，b4=80%）。结果表明，micrantha叶提取物在浓度为20%时对鲜重植物有降低作用，而C.sulfureus叶提取物在40%时对鲜重量植物有降低影响。
