植物激素萘乙酸对云南松种子发芽率的影响研究

Effect of Plant Hormone Naphthylacetic Acid on Germination Rate of Pinus yunnanensis Seeds

我国松科松属的植物种类相对较多,其中,云南松属于常绿乔木,具有较高的利用价值。要想保证云南松能够大量生长,就必须保证云南松种子的成熟率和成活率。我国在植物培育过程中常用的植物激素较多,如萘乙酸、金宝贝根苗状、吲哚丁酸、吲哚乙酸、乙酸以及赤霉素等,主要以NAA(萘乙酸)为研究对象,研究了植物激素萘乙酸对云南松种子发芽率的影响。

There were relatively many species of Pinus in China,among which Pinus yunnanensis was an evergreen tree with high utilization value.However,to ensure the large growth of Pinus yunnanensis,it was necessary to ensure the maturity rate and survival rate of Pinus yunnanensis seeds,which was important to directly affect the germination process of Pinus yunnanensis.There were many phytohormones commonly used in the process of plant cultivation in China,such as NAA,Campbell’s root sprout,IBA,IAA,acetic acid and gibberellin.Mainly focuses on NAA,analyzed the effects of plant hormone naphthoacetic acid on seed germination rate of Pinus yunnanensis.
