Effect of physiological status on rooting of Masbedda (Gymnema sylvestre) cuttings
By demo | January 18, 2008
Vegetative propagation by means of cuttings is an important method for starting new plants identical to the parent plants. Many plants can be propagated with good results by cutting, though the success depends upon the propagators circumstances, the time of year, and the plant to be propagated. The present study was carried out to investigate the effect of physiological stage on rooting of Gymnema sylvestre stem cuttings.
Healthy, double nodded cuttings were made from the mature plant stock established at the Faculty of Agriculture, University of Ruhuna. The cuttings taken from pre-flowering (T1), flowering (T2) and post-flowering (T3) stages were stuck into preformed holes in poly bags filled with moistened rooting medium which consisted of sand, top soil and compost (1:1:1 by volume). They were placed in a shade house and watered once a day. The Completely Randomized Design (CRD) was used with ten replicates. Assessment was done 75 days after for rooting. The percentage survival was not significantly (p 0.05) different between cuttings taken from the pre-flowering (92%) and post-flowering (87%) stages. No significant (p 0.05) differences also in the percentage of callused and rooted cuttings were recorded between T1 and T3. However, number of roots and length of the longest root per cutting were significantly (p 0.05) higher in T1 than any other. Furthermore, T2 showed the lowest figures for all the parameters assessed, indicating that the physiological status of the stock plant at the time the cuttings are excised is of great importance for the rooting process.
