植物可按其插条生长特性分为下列三类: 1.容易扦插,成活率高。有的生根快,能萌发大量或少量的根;有的生根慢,但能逐渐发根。 2.难扦插、生根率低,根少而发根迟。 8.抗逆性强而不生根。胡椒属于容易扦插而生根缓慢的一类植物。用生长素处理,可促进它生根。据报导,胡椒插条用100毫升含1—10毫克阿尔法—萘乙酸的水溶液浸1—3天后,生根和根系生长加速。
Plants can be cut according to their growth characteristics are divided into the following three categories: 1. Easy cutting, high survival rate. Some root fast, can germinate a large number or a small amount of roots; some rooting slow, but can gradually hair roots. 2. Hard cutting, rooting rate is low, the root of hair and hair roots late. Strong resistance without rooting. Pepper is easy to cut and rooting a group of plants. With auxin treatment, can promote its rooting. It has been reported that rooting and root growth accelerated after the pepper cuttings were immersed in 100 ml of an aqueous solution containing 1 to 10 mg of alpha-naphthaleneacetic acid for 1-3 days.
