Effect of different pulsing treatments and holding solutions on the vase life of cut spikes of the orchid, Dendrobium cv. Sonia-17 was studied. Among the pulsing treatments, pre-cooling treatment done at 150C for 12 h recorded maximum spike longevity of 32 days, maximum number of days for wilting of first floret (26 days), maximum number of days for wilting of all florets (38 days) and maximum water uptake (10 ml). In the trial using different holding solutions, AgNO3 (25 ppm) + sucrose (5%) gave maximum vase life of 35 days, maximum number of days for wilting of first flower (17.3 days) and maximum number of days for wilting of all flowers (53.7 days). Pre-cooling treatment done at 150C for 12 h and holding solutions containing AgNO3 (25 ppm) + sucrose (5%) was found to be the best treatments to enhance the vase life of cut spikes of the orchid, Dendrobium cv. SONIA-17.Keywords

The study on characterization of ecotypes of banana (Musa AAB Plantain subgroup) was undertaken in the Department of Pomology and Floriculture, College of Agriculture, Vellayani during April 2016- May 2017 with the objective to characterize the various ecotypes of plantain with respect to clonal characteristics and yield potential. The study revealed that considerable variability existed between the different ecotypes of plantain. The ecotypes varied significantly with respect to all the clonal characters studied, except the number of ridges. Mettupalayam Nendran produced the highest yield but it had long duration. Zanzibar and Big Ebanga were superior in terms of finger characteristics.PSI (Pedicel Strength Index) was the highest in Mettupalayam Nendran (3.17) which was significantly higher than all other clones. The genotypes having high yield like Mettupalayam Nendran, Myndoli etc can be used in further crop improvement programmes to develop high yielding Nendran types.Keywords
