ผลของสาร NAA ต่อการเกิดรากของกิ่งปักชำเฟื่องฟ้า.

The purpose of this experiment was to study the appropriate concentration of 1-Naphthalene acetic acid (NAA) on the growth of Paper Flower, a climbing shrub. A Completely Randomized Design (CRD) was arranged comprising four treatments: control, and NAA at concentrations of 1,000, 2,000 and 3,000 mg/liter. Each treatment consisted of four replications, ten plants per replication. The experiment was carried out during November, 2016 to March, 2017 at Nursery Building, Mahasarakham University. The results showed that the application of NAA at 2,000 mg/liter gave the highest root length, both root sizes and survival percentage for the cutting of Paper Flower. [ABSTRACT FROM AUTHOR]
