The coconut palm (Cocos nucifera Linn.) is one of the most useful palms in the world. It is essentially a tropical plant growing mostly between 20o N 20o S latitudes. Enhancing productivity through cultivation of improved varieties including hybrids is one of the major strategies suggested to make coconut farming more remunerative. Pollination work in coconut for hybrid production requires skilled climbers and is a laborious process that involves climbing the palm many times. Any alternative method that reduces the number of climbing will reduce the labour and make the whole process more cost effective by way of economizing labour component. A study was conducted to find the suitability of detached whole spike with intact male flowers in pollination. A detached whole spike was observed in laboratory condition for seven days. Pollen shed from the spike was quantified and tested for germination. It was observed that pollen release increased gradually and then decreased. Pollen germination was up to 80% on the first day which reduced to 20% after six days. For field validation of the positive results from laboratory, a field experiment was conducted to find out setting
of fruit when whole spike was used for pollination. West Coast Tall (WCT) and Chowghat Orange Dwarf (COD)
cultivars were used in the study. Fruit set up to 30% could be observed which was on par with the traditional method. Whole spike method developed here will reduce the number of climbing required for pollen application to one instead of five required in traditional pollination. Moreover, pollen processing required in the present method can be completely avoided.
