Abstract
Lilium is widely known as one of the most important bulbous cut flower internationally. Improper and inadequate post harvest handling results into quality losses for retailed flowers. To address this issue, a study was conducted to evaluate the effects of silver nanoparticles as higher concentration pulse or a lower concentration as vase solution on the postharvest performance of Lilium cut flowers. The 20 ppm pulsing of cut stems for 24 hours, followed by retention in 2 per cent sucrose solution substantially improve the relative fresh weight, water uptake, water balance, delayed the leaf yellowing. However, higher concentration (40 ppm) extended the vase life by 03 days as compared to the control flowers. The lower concentration (20 ppm) of nanosilver as holding solution enhanced the physiological parameters and controlled the senescence related processes in leaves and petals. Vase life was enhanced to 4.35 days as compare to flowers placed in distilled water as control. The present findings unequivocally highlight that a 40 ppm nanosilver pulse for 24 hours or a 20 ppm + 2% sucrose vase solution can significantly prolong the vase life and positively influence the physiological parameters of cut Lilium flowers.

Abstract
This study aimed to increase the vase life of cut rose flowers by improving the regulation of Programmed Cell Death (PCD). Experiments were carried out on cut rose (Rosa hybrida cv. Dolce vita+) flowers under either physical treatment of Static Magnetic Field (SMF; 15 and 25 mT) for 3 hours, or chemical treatments of silver nano particle (Nano-Ag; 5 and 10 ppm), 6-Benzyladenine (BA; 25 and 50 mg L-1), 1% sucrose, and combinations of 5 and 10 ppm nano-Ag with 3 and 6% sucrose. Results showed that a 15 mT-SMF significantly increased vase life up to 25 days, compared to the controls and to all chemical treatments. Among the chemicals, 5 ppm Nano-Ag and 1% (w/v) sucrose increased vase life to 23 and 18 days, respectively. The smallest decline in fresh weight was observed in the 15 mT-SMF physical treatment. Markedly, the 15 mT-SMF treatment led to the least reduction in Chlorophyll (Chl) content. On the 17th day of the applied different treatments, both Water Uptake (WU) and Relative Fresh Weight (RFW) showed an inverse significant relationship with PCD in cut rose flowers, verifying there markable delayed PCD which is favored the market. As a whole, the most effective induced treatments (15 mT-SMF, 5 ppm Nano-Ag, and 1% Sucrose) are suggested to be promising for enhancing postharvest quality and prolonged vase life of cut rose flowers.

Abstract
Chrysanthemum (Dendranthema grandiflorum (Ramat.) Kitamura cv. Pattriot) is one of the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. The aim of this study was to evaluate the efficacy of salicylic acid (SA) and citric acid (CA) in extending the vase life of chrysanthemum flowers. Therefore, a factorial experiment based on completely randomized design with SA at (0, 100, 200, 300 ppm) and CA at (0, 100, 200 ppm) with 3 replicates and 3 samples (individual flowers) for each replicate, was conducted. Applying SA and CA increased vase life, petal water content (%), initial fresh weight (%) and marketability, significantly. SA treatments increased leaf relative water content (RWC), petal water content (%) and initial fresh weight (%) by 49, 73 and 23 %, compared to the controls, respectively. The highest vase life (21.77 days) was observed for the treatments of SA (300 ppm). The significant increase (300%) in vase life is considered to be due to plant regulating and anti-stress properties of SA and CA. According to the results of this experiment, SA and CA as natural, cheap, safe and biodegradable compounds are suitable alternatives for conventional chemical treatments in order to prolong vase life of cut flowers of chrysanthemum. Commercialization of these compounds for optimum formulations needs further experiments.

Abstract
The effect of different storage temperatures on senescence and postharvest performance in cut scapes of three Iris species (Iris germanica, Iris reticulata and Iris kashmiriana) was studied with the aim to develop a cost-effective storage protocol so as to bring out the transportation of these cut flowers. The scapes were subjected to two different storage treatments-dry storage and wet storage. For dry storage, the scapes were wrapped in moistened filter papers and kept at different storage temperatures [RT (20±2oC), 10and 5oC] for 72 hours. For wet storage, the scapes were kept in buckets containing distilled water (DW) and kept at different storage temperatures [RT (20±2oC), 10oC and 5oC] for 72 hours. After 72 hours storage, the scapes were transferred to flasks containing either DW or sucrose 0.15 M (SUC). Storage of buds for 72 hours at 5oC, followed by transfer to DW and SUC improved longevity in all the three species. Cold storage treatment before transfer to holding solutions improved floral diameter, membrane integrity and maintained higher fresh and dry mass of flowers, sugar content, and soluble proteins. In all the three species studied, enhanced vase life was found associated with the decrease in the total phenolic content of the perianth tissue. In conclusion, our results suggest that wet and dry storage of premature scapes of Irisesfor 72 hours at 5oC, and placing them in sucrose improves the cut flower performance and can be used as effective postharvest storage treatments for these beautiful cut flowers.

Abstract
The aim of this paper was to assess the effect of catechol (CH), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (HQC), as a bacterial inhibitor, on keeping the quality of Gerbera Jamesonii cv. Hongyan cut flowers, known to be limited by vascular occlusion. Blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. The results showed that some stem xylem vessels of the cut flowers were blocked during the vase period, and the blockage consisted of some amorphous or physiological deposition and rod-shaped bacteria located within the 5cm stem end of the cut flower. In addition, CH (1.0mM) or 8-HQC (0.45mM) decreased the blockage of stems and reduced the bacterial growth in the vase solution, but extended the vase life without statistical significance. The combination of CH (0.5 or 1.0 mM) and 8-HQC (0.45mM) decreased the blockage and inhibited the bacteria more than CH or 8-HQC alone, and extended the vase life significantly (P≤ 0.05).

Abstract
Gladiolus (Gladiolus grandiflorus L.) is one of the most widely cultivated, economically important and common flowering plants worldwide including Pakistan. However, its yield of flower is quite low when grown under agro-climatic conditions of Multan. A field experiment was conducted at the Experimental Area, Department of Horticulture, Bahauddin Zakariya University, Multan (Pakistan), during 2010-2012 to investigate the effect of micronutrients (B, Zn and Fe) on growth, flower yield and quality of gladiolus cv. Traderhorn. Eight treatments comprised of either each micronutrient alone or a combination of Fe, B and Zn were applied. Corms were planted within the first week of November 2010, and 2011 on 60 cm apart ridges with 20 cm distance allowed within rows. Twenty corms were planted in each treatment, of three replicates. Micronutrient sprays were applied at 30 and 60 Days After Planting (DAP). Application of the micronutrients significantly increased plant height, leaf chlorophyll content, flower stalk length, flower fresh weight, spike length, florets per spike, florets’ fresh weight and diameter, flower vase-life, flower diameter as well as fresh weight of corms. Leaf number and days to spike emergence were only influenced by a combined application of all the three micronutrients. Among the micronutrient treatments, the treatment containing FeSO4.7H2O, H3BO3 and ZnSO4.7H2O (all at 2% level) performed the best for all the parameters except for number of corm per plant, which was not affected significantly by the foliar application of the micronutrients.
