“…The fixed effects and covariates that had significant effects on traits were included in the subsequent model except for shell colour, considering that the information provided by shell colour recording was partially consistent with pedigree information, and part of the genetic difference would be shielded if shell colour were added. After that, growth traits were compared between samples under different culture modes and with different shell colour, and the significance of differences was tested by one-way ANOVA in R. Phenotypic correlations among growth traits studied were calculated through Pearson correlation analysis using R and were consistent with the reported literature (Boxriker et al, 2018;Li et al, 2019). Genetic parameters were estimated using the mixed model in ASReml-R 4.0 via the REML algorithm.…”

Pacific abalone (Haliotis discus hannai) is one of the most valuable aquaculture species in China. However, the rapid development of the aquaculture industry has caused problem of germplasm degeneration. It is important to carry out genetic improvement of economic traits for H. discus hannai. This study was conducted to estimate genetic parameters of growth traits in Pacific abalone to provide a database for selective breeding programs. Data of 10 growth‐related traits—shell length (SL), shell width (SW), shell height (SH), shell weight (SWT), wet weight (WW), foot muscle weight (MW), soft tissue weight (STW), visceral mass weight (VW), foot muscle weight/wet weight ratio (MWR) and soft tissue weight/wet weight ratio (SWR)—were collected from 1059 adults sampled from 115 families. Significant growth differences existed between abalone under different culture modes. Abalone with red shell colour presented poorer growth performance than the normal shell colour group, and their hybrids displayed mid‐parent heterosis. The heritability values of SL, SW, SH, SWT, WW, MW and STW were 0.65 ± 0.06, 0.63 ± 0.06, 0.51 ± 0.08, 0.59 ± 0.09, 0.54 ± 0.05, 0.43 ± 0.08 and 0.43 ± 0.08, respectively, indicating high heritability. The heritabilities of VW and MWR were moderate, with estimates of 0.36 ± 0.07 and 0.21 ± 0.06, respectively, and SWR had low heritability with value of 0.17 ± 0.06. Genetic and phenotypic correlations among the growth traits were positive, in the ranges 0.24–0.99 and 0.12–0.99 respectively. Genetic correlation coefficients among most of the growth traits were close to or higher than 0.9. The results of this study demonstrate the genetic improvement potential of Pacific abalone in selective breeding. Traits such as SL, SW, SH and WW could be selected and improved simultaneously.

“…Carnation is classified as standard or spray type. The standard type has only one flower per stem, and the spray type has multiple flowers per stem (Boxriker et al, 2018). Carnation is very sensitive to ethylene and it is synthesized in high portions after the full flower opening (Darqui et al, 2017).…”

Standard Carnation flowers (Dianthus caryophyllus cv. Dover) were harvested at the paint brush stage in the early morning, pre-cooled at 4° C for 6-h then moved under dry conditions to the laboratory. Flowers were weighted and treated for 24-h with silver nanoparticles (AgNPs) at 0, 5 or 10 ppm in plastic buckets. After pulsing treatments, cut flowers were transferred to 500 mL glass jars containing 300 mL of preservation solution treatments including, individually, humic acid at 200, 400 or 600 ppm and Aloe vera gel at 2.5%, 5.0% or 7.5% (w/v) till the end of the experiment (when flower color began to fade, petals began to roll). Distilled water was used for the control and to prepare the tested solutions. 2% sucrose was added to all treatments including the control. Addition of all preservatives to vase solutions significantly increased all the studied characteristics of cut flowers compared to control (distilled water, least values). Nanosilver treatments have the potential to be used as preservative solutions for improving postharvest vase life and quality of carnation flowers. An increment in vase life, relative fresh weight, vase solution uptake, flower diameter as well as total chlorophylls in leaves, total carbohydrates and total phenols in leaves and petals was observed, in addition to a decrease in bacterial counts in vase solution. Best results were obtained using 5 ppm AgNPs + 5.0% Aloe vera gel followed by 5 ppm AgNPs +7.5% Aloe vera gel solutions. Aloe vera gel, especially 5.0% level, showed better results than humic acid when used alone or combined with AgNPs. Nanosilver at 5 ppm recorded better results than 10 ppm when used as a single treatment.

“…Dianthus plants all have very significant application value because of their colorful flowers, long flowering period, air purification ability, adaptability to abiotic stress, and so on. Dianthus caryophyllus L. is one of the four major cut flowers worldwide and plays an important role in the flower market [3]. Dianthus plumarius L. is an important environmental protection and greening plant, because of its strong reproductive capacity and rapid growth speed which can effectively prevent soil erosion and soil erosion [4][5][6].…”

Dianthus is a valuable genetic resource for flower breeding. However, study on the genetic similarity of Dianthus plants is rare. In this work, 20 pairs of SRAP markers were used to analyze genetic diversity of 44 Dianthus plants, including 13 lines of wild Dianthus chinensis L., 7 lines of wild Dianthus superbus L. and 24 commercial varieties including Dianthus caryophyllus L., Dianthus plumarius L. and Dianthus barbatus L.. Results showed that precise interspecific and intraspecific genetic diversity was provided in Dianthus plants by using 20 pairs of SRAP molecular markers. The interspecific genetic diversity of Dianthus plants was much abundant and the intraspecific genetic difference of wild Dianthus species was related to their geographical distribution and habitats. In this work, theoretical basis and technical support were provided for crossbreeding and molecular mechanism research of Dianthus plants.
