“…In this respect, results of Chaski et al (2023) proved that bio stimulants that contained seaweed extracts and humic acids improved growth, yield and chemical components of mint crop. The results of Rahbar et al (2023) indicated that foliar spraying with humic acid contributed to increase the carbohydrate rate of the olive leaves.…”

Addition of organo-bio-stimulants may have major impact on bio-chemical attributes of growing media and flower productivity. The current study evaluated the response of lily bulbs for growth, some bio-chemical characteristics, and flowering quality to various growing media which included sand, clay, sand: clay (1:1 v/v), or sand: clay: compost (1:1:1 v/v) supplemented with Humicil and/or Power max. Results proved that the use of growing media led to significant differences in growth, flowering, and chemical component parameters of lily plants. However, there was superiority in these traits due to planting in a medium consisting of a mixture of sand: clay: compost (1:1:1 v/v), followed by sand: clay (1:1 v/v), then clay media. On contrast, planting in sand soil was coincided with a decrease in above-mentioned characteristics compared to the other media. The addition of various organo-bio-stimulants coincided with an improvement in growth, flowering and chemical component measurements. Moreover, adding the mixture of Humicil with Power max, followed by Power max alone showed the greatest effect on improving measurements. The combination between growing media and stimulants showed a significant difference in all measurements of plant growth, flowering and chemical components of lily plants. However, the highest values of these traits coincided with the combination between a mixture of sand: clay: compost (1:1:1 v/v) with the mixture of Humicil and Power max.

“…6). Previous studies have also reported the role of cysteine protease in the senescence of cut flowers such as gladiolus, carnation, alstroemeria, and lilium 9,[53][54][55] . Similar to the GgCYP gene, LG treatment has resulted in the reduction in expression of the GgERS1a in the cut flowers of ethyleneinsensitive gladiolus as compared to control.…”

Gladiolus (Gladiolus grandiflorus Andrews) is a high-valued bulbous cut flower. However, the shorter postharvest life of the gladiolus, limits its marketing and commercial value. In the present investigation, the effect of lemon grass (LG) essential oil as an antimicrobial agent was studied towards increasing the vase life of gladiolus. The results revealed that as compared to control (distilled water), treatment with a lower concentration of 5 µL L−1 LG essential oil prolonged the vase life of gladiolus up to 11 days (d). Scanning Electron Microscope (SEM) observation indicated that the sample treated with 5 µL L−1 LG essential oil showed intact vasculature, suggesting reduced microbial blockage at the stem end which was further corroborated by microbial count. Biochemical analysis suggested an increased level of total soluble sugars, carotenoid content, lower MDA accumulation, and higher activity of antioxidant enzymes in LG treated flowers. Moreover, transcripts levels of genes associated with senescence viz., GgCyP1 and GgERS1a were downregulated, while expression of GDAD1 and antioxidant genes such as GgP5C5, GgPOD 1, GgMnSOD, and GgCAT1 were upregulated in LG treated cut spikes as compared to control. Among various treatments we have concluded that, the vase life of the gladiolus cut spike was improved along with the relative fresh flower weight and diameter of flower at the lower dose of 5 µL L−1 LG oil in the vase solution. Thus, LG oil as an eco-friendly agent has the potential to extend the postharvest life of cut flowers.
