Recently it has been recognized that herbal plants contain endogenous molecules with biostimulant properties, capable of inducing morphological and biochemical changes in crop plants. Therefore, the present experiment was conducted to screen herbal samples for their plant growth promoting properties. Twenty-five herbal extracts were tested for their biostimulating activity on wheat crop (Triticum aestivum) through seed priming. Morphological parameters chosen for evaluation include: percent seed germination, length and weight of seedling, wheat grass length and biomass. Biochemical parameters include: total phenolic and flavonoid, enzymatic activity of catalase and phenylalanine ammonium lyase and antioxidant activity. Results indicated an increase in the tested parameters by the extracts, however the biostimulant property varied between the selected herbal samples. Some of the samples, such as Phyllanthus emblica, Plumbago zeylanica, Catharanthus roseus and Baccopa monnieri, were highly effective in inducing plant growth promoting parameters. Principal component analysis was performed and herbal samples were grouped into categories based on their activity.
最近人们已经认识到，草本植物中含有具有生物刺激特性的内源性分子，能够诱导农作物发生形态和生化变化。因此，本实验通过种子引发对 25 种草药提取物进行了筛选，以检测它们对小麦作物（Triticum aestivum）的促生长特性。选择评估的形态学参数包括：种子发芽率、幼苗长度和重量、小麦草长度和生物量。生化参数包括：总酚和类黄酮、过氧化氢酶和苯丙氨酸解氨酶的酶活性以及抗氧化活性。结果表明，提取物增加了这些测试参数，然而，所选草药样本之间的生物刺激特性存在差异。一些样本，如余甘子、白花丹、长春花和印度菟丝子，在诱导植物生长促进参数方面非常有效。进行了主成分分析，并根据其活性将草药样本分为几类。
