“…After cutting, they were immediately transferred to vases with the different holding solutions in a refrigerated showcase (Refrigeration Plus LLC, Colorado Springs, CO, USA), housing a mixed set of white light LEDs and a constant temperature of 20 °C. The holding solutions were distilled water and Si solution, which was determined to be 75 mg·L −1 , which is in accordance with our lab’s pioneer publication [ 20 ]. From the samples, three stems with flowers were individually labeled, placed in a vase, and set as a single replicate.…”

Peony is an important ornamental plant and has become increasingly popular for cut flower cultivation. However, a short vase life and frequent poor vase quality severely restrict its market value. The study described herein was conducted to investigate the effects of silicon application on the vase life and quality of two cut peony (Paeonia lactiflora Pall.) cultivars, ‘Taebaek’ and ‘Euiseong’. For pre- and/or postharvest silicon application, four experimental groups based on treatments were designed. With silicon treatment, the relevant growth attributes, including the shoot and leaf lengths, stem and bud diameters as well as the leaf width were all remarkably increased. In the postharvest storage, the addition of silicon to the holding solution in the vase was able to significantly extend vase life, delay fresh weight decrease, and improve vase quality, as characterized by the antioxidant enzyme activities and mechanical stem strength. Taken together, silicon application, regardless of the approach, was able to effectively prolong the vase life and enhance the quality of cut peony flowers.

“…Additionally, the application method also influences how Si affects strawberries as its transport in strawberries is unidirectional [ 3 ]. Si has benefits on the photosynthesis, growth, and development, and especially on the resistance to abiotic and biotic stresses in strawberry [ 21 , 22 , 23 , 24 , 25 , 26 ]. It has yet to be clearly determined how silicon affects specific internal mechanisms to increase such stress resistance in strawberry.…”

Silicon (Si) has beneficial effects on not only plant growth but also against biotic and abiotic stresses. However, a few studies focus on how Si application helps strawberry (Fragaria × ananassa Duch.) resist powdery mildew. The aim of this work was to find out the optimal Si application method before cutting propagation to enhance the resistance to powdery mildew in strawberry “daughter” plants. Naturally infected “mother” plants of ‘Sulhyang’, ‘Maehyang’, and ‘Kuemsil’ strawberries were supplied with Si. Potassium silicate (K2SiO3) at a final concentration of 75 mg·L−1 Si was either added to the medium for drenching or sprayed to the leaves of the “mother” or “daughter” plant, or soluble Si fertilizer was used to dress the “mother” plant. The Si application significantly increased the shoot fresh weight of the “daughter” plants. Supplemental Si also increased the contents of phosphorus (P), potassium (K), and magnesium (Mg). In addition, the Si treatment decreased the damage of powdery mildew by increased level of proline content and suppressive reactive oxygen species. After applying Si, the length and density of hyphae on the leaf surface decreased. In addition, the infected area of “daughter” plant leaves covered with powdery mildew decreased. This study also demonstrated that Si increased the expression of resistance-gene and decreased the expression of susceptibility-gene of strawberry. Overall, Si application promoted the growth of the “daughter” plants regardless of the application method. Direct foliar Si spray to the “daughter” plants before cutting propagation is recommended to increase their resistance to powdery mildew.

“…Salt stress is a major abiotic stress contributing to the loss of plant yields and productivity [ 13 , 21 , 22 ]. Salt stress, mainly due to accumulation of toxic Na + and Cl – ions in plant tissues, causes osmotic and ionic stress in plants [ 22 , 23 ].…”

Salt stress is a major constraint of crop productivity because it reduces yield and limits the expansion of agriculture. This study investigated salt tolerance in 26 cultivars of cut lilies (Lilium hybrids) by examining the effect of salt stress on the growth and morphological characteristics of flowers and leaves and their physiological properties (chlorophyll a fluorescence). Salt stress significantly affected the growth and development of cut lilies. Canonical discriminant analysis indicates that the middle leaf width, number of flowers, first flower diameter, petal width, and chlorophyll a fluorescence were correlated with salt stress, whereas plant height, the middle leaf length, days to flowering, and sepal width were less affected by the stress. The cultivars examined were divided into three groups: Group 1 included the salt-sensitive cultivars, which failed to develop normal flowers; Group 2 included cultivars sensitive to salt stress but tolerant to osmotic stress; and Group 3 was the salt-tolerant group, which developed commercially valuable flowers. In conclusion, the cultivars contained a variable range of cut flower characteristics and growth traits that can be employed for lily breeding programs and as material for molecular mechanisms and signaling networks under salt stress.
