“…Prolonging leaf longevity was connected with delay of chlorophyll degradation, which, in turn resulted in keeping green colour of the leaves for a longer period of time. Similarly in Zantedeschia aethiopica the use of gibberellic acid resulted in six-fold extension of post-harvest longevity (Skutnik et al 2001). In a study conducted by Skutnik et al (2004) gibberellic acid delayed chlorophyll degradation in leaves of both Zantedeschia aethiopica and Zantedeschia elliottiana, simultaneously extending their post-harvest longevity.…”

(Prague), 40: 172-176.Conditioning is a simple and eff ective method of post-harvest longevity of both fl owers and fl orists' greens. Performing this treatment immediately after harvest by the producer increases the quality of fl oral products expressed as their post-harvest longevity. Th e purpose of this study was to assess the infl uence of four growth regulators from the gibberellin and cytokinin groups applied as a 4-h conditioning treatment of leaf blades and to determine any eff ects on post-harvest longevity of leaves of Limonium latifolium. Th e leaves were harvested early in the morning from the department of ornamental plants collection. Selected leaves were fully-developed and had no damage or discolouring. Gibberellic acid, benzyladenine, meta-methoxytopolin and its riboside at the concentrations of 25, 50 and 75 mg/dm 3 were taken up in a solution for 4-h leaf-conditioning of Limonium latifolium at the temperature of 18-20°C. After the conditioning treatment the leaves were placed in distilled water. Leaves placed into distilled water immediately after cutting served as control. Gibberellic acid, benzyladenine and topolins applied as leaf conditioning treatment extended the post-harvest longevity of leaves of Limonium latifolium. Examined growth regulators, with the exception of riboside of meta-methoxytopolin, also had a favourable eff ect on the index of leaf greenness.

“…Short-term leaf blades soaking in conditioning solutions is also possible (Janowska et al 2012). Due to the diff erences in ageing processes in leaves as compared to fl owers, standard conditioning mediums are usually not very eff ective and they may even lower the decorative values (Skutnik et al 2001).…”

“…There may be an interaction of nitrogen with carbohydrates, photosynthesis and plant hormones on the role of N in postharvest of flowers [Druge 2000, Skutnik et al 2001. Carbohydrates and plant hormones are vital internal factors regarding postharvest quality of ornamentals which are strongly affected by nitrogen levels and N sources [Marschner 2011].…”

“…Despite ambient temperature is the major environmental factor in postharvest quality and shelf life of cut flowers; however, many other factors such as humidity, microbial effect and nutrient elements can also influence cut flower's shelf life [Skutnik et al 2001, Sairam et al 2011. Ethylene, on the other hand, is the main compound that mediates many physiological and biochemical functions in plant tissues including aging and senescence [Pun and Ichimura 2003, Souri et al 2009, Marschner 2011.…”

This study was done using three nitrogenous compounds to evaluate their effects on postharvest characteristics of chrysanthemum (Chrysanthemum indicum) cut flowers. The study consisted of three separate and parallel experiments, in which ammonium sulfate, calcium nitrate and potassium nitrate were used in different concentrations of zero, 50, 100, 200 and 500 mg dm -3 N for pretreatment of stems for 6 hour before transferring to holding d-water solution. The results showed that petal ion leakage and leaf SPAD values were increased by increasing ammonium sulfate, but not calcium or potassium nitrate. Petal carotenoids were increased by pretreatment of ammonium sulfate and potassium nitrate. There was constant increase in water uptake by increasing the levels of calcium nitrate and potassium nitrate, while ammonium sulfate at high concentrations (200 and 500 mg dm -3 N) resulted in significant less water uptake compared to control. Ammonium sulfate in 50 and 100 mg dm -3 increased shelf life of pretreated stems, but higher concentrations significantly reduced cut flowers shelf life. Increasing concentrations of calcium nitrate and particularly potassium nitrate have led to prolongation of flower shelf life to 12 days compared to 6 days of control. The results indicate that pretreatment of chrysanthemum cut flowers with ammonium sulfate in rather low concentrations or with moderate to high concentrations of calcium nitrate or potassium nitrate can significantly improve shelf life and postharvest flower qualities.

“…The process of ageing in florists' greens may be regulated using growth regulators from the group of cytokinins and gibberellins [2,[4][5][6]. Their effectiveness depends on the species, cultivar, method of application, and the concentration of applied regulators.…”

Post-harvest longevity of ×Heucherella L. leaves after the application of benzyladenine sprayed on maternal plants

2016

View full text Add to dashboard Cite

Analyses were conducted on leaves of two ×Heucherella L. cultivars: 'Solar Power' and 'Kimono' . Leaves were harvested at two dates: spring (2014-05-22) and summer (2014-07-26). Prior to each leaf harvest day, the maternal plants were sprayed with benzyladenine (BA) at a concentration of 100, 300 and 600 mg dm . After being cut, the leaves were placed in containers with distilled water. In the cultivar 'Solar Power' , BA at a concentration of 100-600 mg dm −3 had an advantageous effect on post-harvest longevity of leaves harvested in summer, improving it by 31.7-98.3%, while in the cultivar 'Kimono' BA at the above-mentioned concentrations improved post-harvest longevity of leaves harvested both in spring and summer by almost 2 months. BA at a concentration of 100-600 mg dm −3 inhibited proteolysis in leaves of the tested ×Heucherella cultivars, except for leaves of the cultivars 'Solar Power' and 'Kimono' harvested in summer from plants sprayed with BA at a concentration of 100 mg dm −3. In these leaves, the protein level was comparable to that in the control leaves. In leaves treated with BA at a concentration of 100-600 mg dm −3 , the content of saccharides was higher than in the control plants harvested in the spring and summer.
