POST HARVEST HANDLING OF CUT-FLOWER ROSE (original) (raw)

Present status and future prospects of cut rose (Rosa ×hybrida) flower production and postharvest management in Punjab, Pakistan, were investigated. Cut roses were the leading flower crop in the area under study, but production systems and practices were outdated and primitive, resulting in cut stems that were not acceptable in international markets. The majority of growers (65%) had only basic education (grade 10 or less) and 57% had small landholdings (<1 ha); therefore, they did not have modern production techniques and resources for high-quality cut rose production. Moreover, lack of production and postharvest facilities, ignorance of both public and private resources, and poor production and postharvest practices were prevalent. Growers' training regarding production and postharvest management would be required to lift the quality standards of this industry up to the international level. However, a positive trend was observed in cut rose businesses as more than half of g...

A field investigation was carried out during July 2008 to April 2009 in the farmer field of Gunjanagar-5, Chitwan, Nepal to evaluate the influence of time and intensity of pruning on quality and postharvest performance of cut rose cv. Super Tata (Rosa hybrida). The field experiment was laid out in a completely randomized block design with nine treatments combinations and replicated thrice. The treatments comprised of three dates of pruning i.e. 30th July, 15th August and 30th August and three pruning intensities i.e. heavy (6 buds per plant), medium (12 buds per plant) and light (18 buds per plant). Postharvest study was conducted in all the above treatments and repeated thrice at the central laboratory of IAAS, Rampur. Both time and intensity of pruning significantly affected quality and postharvest performance. Flowers stem diameter, fresh and dry weight of flower stem were found higher in July 30th pruned rose plants while, flower stem length was found longer (47.67cm) in August 15th ones. Flowers stem length (50.33cm) and diameter (0.60cm), length (2.91cm) and diameter (2.29cm) of floral bud, fresh and dry weight of flower stem were found highest from heavily pruned plants. The flowers from heavily pruned plants had early bud opening (4.53 days), highest floral diameter (9.13cm) and longest vase life (10.64 days). From this study, it revealed that highest quality cut flowers can be produced by heavy pruning whereas more quantity can be achieved by light pruning.

An experiment was conducted to evaluate the performance of rose cultivars and their categorization based on color, fragrance and use. Field experiment included forty four rose cultivars coded from V1 to V44. It was found that all rose cultivars varied significantly for the studied characters like number of shoots/plant, leaf area, chlorophyll content, number of flower/plant and petals per flower. Rose cultivars were categorized in nine groups in accordance to color, three groups in accordance to the fragrance and two groups in accordance usage excluding the wild type. V3 (Tajmahal), V4 (Yellow star), V14 (Lavender gold), V16 (Compassion), V21 (SAU hero), V23 (Yellow gold), V25 (Sleepy moon), V26 (Sweet doll), V30 (Chrysanthemum rose) and V35 (Sweet sakata) cultivars were found as the cut flowers and rest were pot/bedding flower. Among the 44 cultivars desired one could be isolated easily for the specific purpose. Roses are vegetatively propagated and they are selected for defined traits such as stem length, flower bud, flower number, flower size and flower qualities (shape, color, fragrance). Breeding to modify a single characteristic generally results in changes to other characters as well.

A study was conducted at Department of Floriculture and Landscaping, College of Horticulture, Vellanikkara, to evaluate the performance of cut flower rose varieties and to select suitable varieties for commercial cultivation in Kerala. Three IIHR varieties viz. , Arka Ivory, Arka Pride, and Arka Swadesh, and seven exotic rose varieties viz., Gold Strike, Noblesse, Revival, Taj Mahal, Corvette, Emma and Peach Avalanche were selected for the study. The varieties varied significantly with respect to various vegetative and floral parameters. The variety Taj Mahal was superior with respect to plant height (52.83 cm). Highest number of flowers were recorded in variety Revival (12.45) which was on par with Arka Ivory (11.38), Arka Swadesh (10.10) and Peach Avalanche (9.87). The variety Taj Mahal had highest number of petals (79.54). Vase life was highest for the varieties Revival (4.83 days), Taj Mahal (4.75 days) and Noblesse (4.75 days). The genetic estimates of heritability (%) and gene...
