BACKGROUND The perishability of Brassica chinensis poses a major challenge to distribution and marketing. The aim of this work was to select a suitable modified atmosphere packaging to retain the overall quality and bioactive compounds during storage. RESULTS Four types of biorientated polypropylene packaging (BOPP)--BOPP03, BOPP04, BOPP05 and BOPP06--with different perforations were evaluate...

Alstromeria is a new cut flower in Iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. Premature yellowing of leaves in cut flowersAlstromeria before petal fall is the most important factor limiting the vase life of flowers. To delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried ...

alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

The changes in chlorophyll content, antioxidant enzyme activities and senescence in Chinese kale (Brassica oleracea var. alboglaba) irradiated with different UV-C dosages (1.8, 3.6, 5.4 and 7.2 kJ m-2) were determined during storage at 20°C. The irradiation dose of 3.6 and 5.4 kJ m-2 delayed leaf yellowing depicted as higher hue values and chlorophyll contents and lower activity of chlorophylla...

This study reveals by in vivo deuterium labeling that in higher plants chlorophyll (Chl) b is converted to Chl a before degradation. For this purpose, de-greening of excised green primary leaves of barley (Hordeum vulgare) was induced by permanent darkness in the presence of heavy water (80 atom % (2)H). The resulting Chl a catabolite in the plant extract was subjected to chemical degradation b...

Although the loss of green color in senescent leaves and ripening fruits is a spectacular natural phenomenon, research on chlorophyll breakdown has been largely neglected until recently. This review summarizes knowledge about the fate of chlorophyll in degreening tissues that has been gained during the past few years. Structures of end- and intermediary products of degradation as well as the bi...
