Abstract
A research programme was carried out for a period of one year from January 1987 to December 1987, to study the effect of season and position of bud in budding of rose. The experiment was laid out in factorial CRD with three replications. The treatments consisted of combinations of three varieties, ‘Ambassador’, ‘Pink Panther’ and ‘Princess’, with scion buds from five positions, starting immediately below the flower. Budding was done at fortnightly intervals.
The effect of environmental parameters on success of budding; influence of period of budding, varieties and scion bud position on further vegetative growth and flower; influence of C/N ratio on bud take have been proved by the results of the present study. There was no significant difference among the three varieties, ‘Ambassador’, ‘Pink panther’ and ‘Princess’ in respect of success in budding. A high rate of 82-98 per cent success was recorded during the rainy season of second fortnight of August to first fortnight of October. The period from first fortnight of February to second fortnight of March was the least favourable season. Higher temperature was found to be detrimental for the success in budding. Rainfall and relative humidity favoured the bud take. More sunshine hours was detrimental. The preceding, current and succeeding fortnights of budding, were found to be critical, as far as success in rose budding is concerned.
The period of budding significantly influenced the biometric characters under study. The variety and bud position was found to exert significant influence on some of the biometric characters. The first and second buds were early to sprout and flower till the production of first flower bud, but the plants were comparatively weak. The fourth and the fifth buds were found to be better for budding when plant vigour was considered. Correlations were worked out between the thirteen biometric characters under study. The scion C/N ratio significantly influenced the bud take while the rootstock C/N did not significantly influence the take. The carbohydrate and nitrogen content varied significantly throughout the year and with scion bud position and variety.
