rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

The most popular fragrant cut rose cultivar in Japan is ‘Yves Piaget’, but its petals often become malformed after harvest. These flowers, referred to as “incurved flowers”, are characterized by curving toward the adaxial side which prevents normal flowering and significantly decreases flower quality. It has been reported that jasmonic acid (JA) affects petal growth, could suppress emergence of...

a study was conducted to standardize production and postharvest handling of lily (lilium longifolium l. cv. mero star). in production trial, three plant densities viz.10, 20 and 30 cm between plants in 60 cm spaced rows and two planting depths viz.7.5 and 15 cm were compared. increased plant growth, yield and quality was recorded when plants were grown at a close spacing of 10 cm with 15 cm pla...

Rose is among the most important cut flower crops worldwide. The vase life an indicator of rose quality. composition solution directly affects life. Neoagaro-oligosaccharides (NAOS) are degraded seaweed-derived polysaccharides that constitute a group compounds with small molecular weight and good water solubility. Oligosaccharide treatment can extend postharvest longevity certain types flowers;...

to investigate the role of silicon (si) in alleviating the effects of salinity on quality and quantity of cut rose flowers ‘hot lady’cultivar was grown in hydroponic culture media. different levels of silicon (0, 50, 100 and 150 mg l-1) as si were mixed with 28 mm nacl (ec ≈3.8 ds m-1) levels, used in an rcbd experimental design.the results indicated that si in 50 and 100 mg l-1 had beneficial ...

tuberose cut flower is considered one of the most important cut flowers from the viewpoint of production and export. the failure of developing buds into open ones and the abscission of floret are two of the common problems in the postharvest of tuberose cut flower that diminishes its longevity and therefore its market quality. this research was conducted to investigate the effect of 2,4-d sucro...

The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...
