“…Conversely, values less than 100 recorded in the roots indicate lower root growth in some treatments where Ce was applied, compared to the control. Lanthanum (La), a member of the REEs, can induce hormetic dose responses in plants [58][59][60][61]. Hormesis is a natural dose response phenomenon characterized by a low-dose stimulation causing positive effects, and a high dose inhibition triggering toxic effects [62,63].…”

The rare earth element (REE) cerium (Ce) can act as a biostimulant in diverse crop plants. The effects of 0, 5, 10, and 15 µM Ce (supplied as CeCl3 7H2O) on seed germination and the initial growth of tomato (Solanum lycopersicum L.) cv. Vengador were evaluated. After a 12 h imbibition, the weight of the seeds treated with 15 µM Ce was 37.5% greater than that observed in the control. The germination index of the seeds treated with 5 µM Ce was greater than 100% (101.93%), though when applying 10 µM Ce this index was 17.53% lower than the control seeds. Nevertheless, Ce treatments did not significantly affect the coefficient of velocity of germination, relative seed germination, germination index, radicle length, dry biomass, or relative growth. Interestingly, shoot length increased significantly in the treatments with 5, 10, and 15 µM Ce. This tendency was also observed in the dry biomass weight and relative growth of the shoots. Hence, Ce has a stimulating effect on germination and initial growth in tomato cv. Vengador shoots. In particular, there was a priming effect of Ce on seeds, reflected in a higher weight gain in Ce-treated seeds, which indicated greater water absorption. Therefore, Ce can be an alternative to accelerate the production time of tomato seedlings in seedbeds.

“…In addition, nitric oxide [ 21 ] and ubiquitination [ 22 ] as endogenous signal are involved in flower senescence. And the antioxidants, such as nano-silver [ 3 , 23 ], lanthanum [ 24 ] and 8-hydroxychinoline [ 3 , 25 ] delay petal senescence.…”

Background: Background: Flower senescence is the last stage of flower development and affects the ornamental and economic value of flower plants. There is still less known on flower senescence of the ornamental plant Camellia lutchuensis, a precious species of Camellia with significant commercial application value. Methods: Methods: Transcriptome sequencing was used to investigate the : By Illumina HiSeq sequencing, we generated approximately 101.16 Gb clean data and 46649 differentially expressed unigenes. Based on the different expression pattern, differentially expressed unigenes were classified into 10 Sub Class. And Sub Class 9, included 8252 unigenes, was highly expressed in the flower senescent stage, suggesting it had a potential regulatory relationship of flower senescence. First, we found that ethylene biosynthesis genes ACSs, ACOs, receptor ETR genes and signaling genes EINs, ERFs all upregulated during flower senescence, suggesting ethylene might play a key role in flower senescence of C. lutchuensis. Furthermore, reactive oxygen species (ROS) production related genes peroxidase (POD), lipase (LIP), polyphenoloxidase (PPO), and ROS scavenging related genes glutathione S-transferase (GST), glutathione reductase (GR) and superoxide dismutase (SOD) were induced in senescent stage, suggesting ROS might be involved in the flower senescence. Besides, the expression of monoterpenoid and isoflavonoid biosynthesis genes, transcription factors (WRKY, NAC, MYB and C2H2), senescence-associated gene SAG20 also were increased during flower senescence. Conclusion: Conclusion: In C. lutchuensis, ethylene pathway might be the key to regulate flower senescence, and ROS signal might play a role in the flower senescence.

“…Preservatives comprise commonly used chemicals to delay flower senescence and retain the ornamental value because of their low cost, ease of use, and obvious fresh-keeping effects (G omez-Merino et al, 2020;Rabiza-Swider et al, 2019;Shabanian et al, 2019). For decades, many protocols or preservatives have been developed for several cut flower species, such as rose (Rosa hybrida), carnation (Dianthus caryophyllus), and gerbera (Gerbera hybrida) (Ren et al, 2017;Seglie et al, 2011;Shabanian et al, 2018).…”

Luculia pinceana is a potential cut flower because of its long-term blooming inflorescences and charming fragrance. However, its narrow distribution area and unexplored wild status severely restrict its applications, thus leading to the scientific research of cut L. pinceana flowers. To our knowledge, there is no available published information about the postharvest fresh-keeping of L. pinceana. During this study, the cut flowers of L. pinceana were tested using nine preservatives with different concentrations of sucrose and 8-hydroxyquinoline (8-HQ) to evaluate the fresh-keeping effects. Through the investigation and analysis of vase life, bud opening and abortion rate, water balance, malonaldehyde (MDA) content, and peroxidase (POD) activity, we selected and identified the best vase solution for cut L. pinceana flowers. The results suggested that the preservative of 1% sucrose and 100 mg/L 8-HQ could significantly prolong the vase life of cut L. pinceana flower up to 9 days compared with water control. This solution positively affects flower bud blooming, delays flower senescence, improves the water balance, inhibits the MDA accumulation, and increases POD activity. Therefore, this preservative is suitable for the fresh-keeping of cut L. pinceana flowers. Our study is the first to report the effects of preservatives on cut L. pinceana flower. The results showed that the low-sugar-containing (1% sugar) preservatives can effectively improve the ornamental quality of fresh flowers and demonstrated that the postharvest fresh-keeping of L. pinceana requires low sugar and is insensitive to microorganisms.
