“…The ideal temperature for stratification is in the range of +3 to +5 • C [28]. Reported average germination rates of chestnut seeds are within the range of 65% to 87% [29,30]. Germination rates obtained in this study were comparable at 53% to 80% (Table 1).…”

The quantity and quality of seedlings in the nursery has an impact on the success of re-establishment and later growth. High germination rates enable a sufficient number of seedlings, and their quality is assessed using a number of parameters, including seedling height and root collar diameter. These parameters are influenced in some species by seed size, but the correlation between them is species-specific. The model species in this research was sweet chestnut (Castanea sativa Mill.), and seeds from 12 populations from two distinct biogeographical regions of Croatia were collected. We examined the influence of seed size on four parameters: germination rate, seedling height, root collar diameter and sturdiness quotient. Seed size has been shown to have a positive influence on both seedling height and root collar diameter, whereas no such correlation was noted for germination rate and sturdiness quotient. Significant differences in nut size and seedling growth parameters were found between the Mediterranean and continental populations, with higher values observed in the coastal Mediterranean populations. We concluded that seed origin and seed size have a significant impact on seedling growth and are important factors to consider when choosing seed material. Further nursery operations should consider seed origin and local environmental conditions when choosing seedlings for reforestation efforts and general forest operations.

The progress of charcoal root rot (CRR) disease in Pinus radiata seedlings caused by Macrophomina phaseolina was evaluated in greenhouse and field trials. In one greenhouse trial P. radiata was sown in a sandy soil with pathogen inoculum densities (ID) ranging from 25 to 1000 cfu.g -1 . After two months, the seedlings were established under three soil moisture content (SMC) levels corresponding to 100%, 75% and 50% of field capacity (FC). In one field trial, P. radiata was sown on microplots infested with ID of 50 to 250 cfu.g -1 . In the greenhouse trial the disease incidence was related with the pathogen ID and SMC. At 100% FC, the seedlings remained asymptomatic until the experiment ended, however M. phaseolina was able to infect the roots. In the field trial, the disease progress curves were similar to those of the greenhouse trial in response to ID and SMC but the plant mortality due to CRR incidence did not exceed 50%. The monomolecular model was the one that best fitted the disease progress curve data for both trials and most treatments. Knowledge of the existing ID of M. phaseolina in the soil, combined with information on SMC, may be important for predicting CRR epidemics in P. radiata nurseries.

“…On the other hand, exotic species that predominated was Castanea sativa (Sweet chestnut) a tree whose fruit plantations are in Biobío Region, and also in plantations for forestry use in the La Araucanía Region [32]. The Biobío and La Araucanía Regions also had Rubus ulmifolius (Elmleaf blackberry), species of fruit distributed from Coquimbo to Los Lagos Regions [33].…”

The chemical composition and quality of honey depend on the floral and geographical origin, extraction techniques, and storage, resulting in a unique product for each area. Currently, consumers are not only concerned about the chemical composition, quality, and food safety of honey, but also about its origin. The objective of this study was to characterize honeys produced in Chile’s central-southern region from a mineral and botanical perspective, thus adding value through differentiation by origin. Two hundred honey samples were used and underwent analysis such as melissopalynological composition, nutritional composition, and color. Forty-seven melliferous floral species were identified, out of which 24 correspond to exotic species and 23 to native species. Fifty-six percent were classified as monofloral honeys, 2% as bifloral, and 42% as multifloral. Moisture mean values (17.88%), diastase activity (15.53 DN), hydroxymethylfurfural (2.58 mg/kg), protein (0.35%), and ash (0.25%) comply with the ranges established by both the national and the international legislation; standing out as honeys of great nutritional value, fresh, harvested under optimal maturity conditions, and absence fermentation. Regarding color, light amber was prevalent in most territories. The territory where honey was produced, denoted relevant differences in all the parameters studied.
