Improvement of Propagation by Hardwood Cuttings with and without Using Plastic Pavilions in Fig (Ficus carica L.)

Abstract

Improvements of fig (Ficus carica L.) cutting propagation with and without using plastic pavilions were conducted at the Inthanon Royal Project Research Station (Khun Huai Hae area) as experiment 1 and at Pang Dah Royal Project Research Station as experiment 2, both in Chiang Mai
province, at the elevation of 1,300 and 720 m above mean sea level, respectively. From experiment 1, larger cutting sizes in comparison with those of 0.6 – 0.8 and 1.0 – 1.2 cm was partially attributable to increased bud and root growth, as indicated by the number of emerged buds and roots in the “Brown Turkey” cultivar. In experiment 2, “Brown Turkey” was the most feasible cultivar for the region when using plastic pavilion, followed by “Dauphine” and “Lisa”. Comparison between treatments with and without the pavilions among cultivars suggested that cuttings placed in pavilions increased the number of emerged buds and roots earlier than those without pavilions. The results indicated that using plastic pavilion increased the temperature that promotes early callus formation of buds and roots in the propagation of fig cutting in cool area such as the Inthanon Royal Project Research Station.
