Influence of Shading and Anatomical Structure of the Stem Cutting on Rooting Performance of Fig (Ficus Sp.)

Abstract

Fig (Ficus sp.) belongs to tropical and subtropical climates which have great potential for the commercial cultivation. Cutting is the most common and effective method of propagation for figs which is influenced by different exogenous and endogenous factors. In this light, a study was conducted to observe the responses of stem cutting of fig (Ficus sp.) of one exotic and two indigenous varieties (Teen- Ficus carica; wild fig- Ficus hispida and joggo fig- Ficus racemosa) in respect of duration of shade and anatomical status of stem. The study was laid in Completely Randomized Design (CRD) with two factors (duration of shade and cultivars) and three replications of the treatments. The four different treatments of shade duration were as T1= open or control, T2=3 days of shading, T3= 6 days of shading and T4= 9 days of shading. Data were collected on root and sprout growth of the cuttings at weekly interval from two weeks of planting the cuttings in sand filled plastic cups. When the duration of shading increased, the teen (Ficus carica) showed the longest sprout (1.59 mm) and root (2 mm) as well as maximum number of root (5.67) and sprout (2.33). Better rooting performance was found in teen and it was very low in wild fig. A relationship between rooting performance and anatomical structure was clearly observed in this study. Long period of shading has positive effect on number and length of sprout in teen and wild fig. On the other hand, short period of shading minimized the days required for sprouting in teen Presence of thin cuticle, thin trichome and the absence of druses crystal in ground tissue and medulla also enhanced the performance of stem cutting of teen.
