Investigation and determination effects of bulb size and sowing date on quantity characteristics of Polianthes tuberose in greenhouse condition of Jiroft
Journal Title: International Journal of Farming and Allied Sciences - Year 2018, Vol 7, Issue 1
Abstract
Planting date and bulb size are the most effective of parameters affecting growth and flowering in bulbous plants. So, for study of planting date and bulb size on yield and flowering quality in tuberose, effect of three bulb sizes, including 1/5, 1/5-2/5 and 3-4 cm in diameter and planting date: 1 May, 1 June, 1 July on quantity charactiristics of Polianthes tuberose in greenhouse condition of Jiroft. The experiment was carried out as a splite plot in a complete randomized block design with three replications. All the data was subjected to analysis of variance (ANOVA) using of SAS software and the means separated using the Duncan's Multiple Rang Test. percentage of germination, leaf number and vegetative growth of plantlets, days to emergence, length, diameter and number of inflorescence spike, days from emergence to first floret evaluated . Results revealed that, period of growth and flowering decreased by July Time and large bulb size resulted in vigorous growth, maximum yield and more number of bulbils as compared to small and medium sized bulbs. It was concluded that large sized bulbs with 3 – 4 cm diameter are best for planting of tuberose. planting date between of 1 May and 1 of June is recommended for good growth, best cutflower and more corms production of tuberose under greenhouse conditions of Jiroft.
