In order to evaluate the adaptation and ornamental potential of Allium spp endemic to Iran, an experiment was conducted in Agricultural Research Station of Lorestan University under Khorramabad climatic conditions during 2014-2015. A completely randomized design was used for the experiment with 21 treatments (species-location) with three replications. Phonological and morphological characteristic at growth stage was recorded. Analysis of variance showed significant (p<0.01) differences among species on all traits indicating genetic diversity of the studied species. Cluster analysis and principle component analysis were used to assess the ornamental potential of the studied species and the most important ornamental characteristics i.e. scape length, the diameter of the inflorescence, flower longevity and flower color were evaluated. Biplot were depicted on the basis of both the first and second component that showed 54% of variations. In the biplot and cluster analyses, the species were placed into distinct groups associated with their potential ornamental value. According to the results, Allium iranicum collected from the Alborz-Dizin with large inflorescence (63.28 mm), beautiful flower color (purple) and being green in winter, and Allium oschaninii species collected from Khorasan-Chenaran with great flower longevity (54 d), beautiful form and large scape length (95 cm) were identified as good potent ornamental species.

Abstract
In this study, postharvest characteristics of eight cut rose cultivars (Valentine, King Pride, Prima Donna, Black Baccara, Victory, Papagayo, Royal Baccara and Yellow Island) were investigated in a growth room with temperature of 20 ºC, relative humidity of 50% and light intensity of 10 µmol ...

In this study, postharvest characteristics of eight cut rose cultivars (Valentine, King Pride, Prima Donna, Black Baccara, Victory, Papagayo, Royal Baccara and Yellow Island) were investigated in a growth room with temperature of 20 ºC, relative humidity of 50% and light intensity of 10 µmol m-2 s-1 in autumn 2008. Among cultivars significant differences were found for all of the attributes evaluated. According to the results, King Pride with 17.7 days and Papagayo with 9.4 days showed the longest and the shortest vase life, respectively. After King Pride, Royal Baccara, Yellow Island and Black Baccara showed a high longevity. Flower peduncle was the largest in Yellow Island and King Pride and the lowest in Papagayo. Moreover, fresh weight loss was the highest in Papgayo and the lowest in King Pride and Yellow Island. King Pride showed the highest water uptake while Papagayo showed the highest water loss. Both water uptake and water loss were the lowest in Victory but its flower buds didn't open fully. Moreover, King Pride and Papagayo showed the highest and the lowest stomatal density, respectively. Overall, cultivars with larger flower and peduncle diameter and higher relative fresh weight, water uptake and stomatal density showed higher vase life. King Pride, Royal Baccara and Yellow Island were selected as best cultivars based on the vase life and other postharvest characteristics.
