“…Shinners). In Anthurium andreanum, vase life was extended up to 17 days when flower stalks were sprayed with 6-BAP (Favero et al, 2020). In our study, the application of 6-BAP succeeded in retarding the opening rate of individual flowers and the first opened flower senescence, resulting in a longer commercial life span although total vase life was not altered.…”

Hormonal endogenous changes in response to the exogenous 6-benzylaminopurine application in pre- and post-harvesting lilium flower stalks

Phyto-hormones play a key role in regulating plant responses to stress. Cytokines are a type of phyto-hormones involved in the regulation of many important biological processes related to growth, development, and response to environmental variables. The exogenous application of cytokines increases the possibility of delaying senescence; however, this is a physiological process, and, under certain conditions, degradation processes may be triggered. The effect of 6-bencilaminopurine application and the endogenous hormonal changes involved in lilies floral stalks after their cutting were studied. In order to improve vase life and quality of Lilium longiflorum ‘Brindisi’ flower stalks, they were sprayed with 6-BAP, at a concentration of 300 ppm at pre-harvest, post-harvest, and pre- and post-harvest stages. After that, they were compared to non-sprayed control stalks. The application of 6-BAP caused endogenous hormonal changes in abscisic acid and cytokinin levels, and the most effective treatment was pre-harvest spraying. This treatment proved to be an appropriate method to improve the stalk tolerance to post-harvest stress as it delayed the appearance of senescence symptoms and reduced the speed of chlorophyll degradation with differences of up to 10% with respect to untreated stalks. In addition, the opening of flowers was delayed by up to 2 days, although there were no significant differences in total vase life.

“…Older, senescent leaves become "source leaves" accumulating mineral nitrogen and progressively losing organic compounds such as carbohydrates and amino acids (Masclaux et al, 2000). The opposite effect, i.e., an increase in the carbohydrate content accompanied by a decrease in the phenolic compounds content was observed following the exogenous application of 6-benzylaminopurine, which prolonged post-harvest life in Anthurium andraeanum (Favero et al, 2020). Quirino et al (2001), on the other hand showed that certain monosaccharides, particularly galactose, fructose and glucose, accumulate in the senescent leaves of Arabidopsis.…”

“…6-BA treatment delays ripening and senescence in mango fruit by regulating ROS production and membrane lipid metabolism [ 11 ]. Treatment with 6-BA has also been shown to prolong the storage life of dahlia [ 12 ], improve postharvest quality of A. andreanum ‘Apalai’ flowers [ 13 ], and maintain the postharvest quality of some vegetables, such as Chinese chives [ 14 ] and broccoli [ 15 ]. However, the effects of 6-BA on vegetables vary substantially among plants.…”

The cytokinin 6-benzyladenine (6-BA) is widely used to regulate the growth of horticultural crops. However, it is not clear how postharvest treatment with 6-BA at various concentrations affects the quality of Chinese flowering cabbage. In this study, harvested Chinese flowering cabbage was foliar sprayed with 6-BA solution at concentrations of 5, 10, 20, 40, and 80 mg·L−1. All 6-BA treatments protected the quality of Chinese flowering cabbage during storage, and the treatment with 20 and 40 mg·L−1 6-BA showed the most obvious effect. Treatment with 6-BA reduced leaf yellowing degree and weight loss rate; maintained high chlorophyll a and chlorophyll b contents; suppressed the declines in ascorbic acid and soluble protein; enhanced antioxidant capacity; and reduced oxidative damage in cabbage leaves. Furthermore, 6-BA treatment upregulated the expression of antioxidant genes and the activities of SOD, POD, and CAT, while inhibiting the expression of senescence-related gene (BrSAG12) and chlorophyll catabolic genes (BrPAO, BrPPH, BrSGR1, BrNYC1, BrRCCR). These results suggest that postharvest 6-BA treatment enhances antioxidant capacity, delays leaf senescence, and inhibits chlorophyll degradation, thereby maintaining the quality of Chinese flowering cabbage during storage. The findings of this study provide a candidate method for preserving Chinese flowering cabbage after harvest.
