The main aim of this study was to evaluate the effect of irrigation and fertilization on growth dynamics of ‘Imola’ clone, an elite poplar crossed from Populus deltoides Bartr. and Populus nigra L. for short rotation coppice purposes. Using a split-plot design with three replications, two treatments were applied (irrigation and fertilization) with two levels each one: ‘no’ and ‘yes’; 4 theses were considered: irrigation-only (IRR), fertilization-only (FRT) and the irrigation with fertilization (IRF) and control (CRT). At the end of the first 5-year cycle the average yield, in dry matter, was 36.8 Mg ha -1 for non-irrigated plots and 80.8 Mg ha -1 for irrigated plots. While no statistical evidence was detectable for fertilization treatment, a Linear Mixed Model analysis applied to data highlighted the Summer (June-August) as key season for the irrigation of trees. Conversely, interaction between irrigation and fertilization negatively affected growth in the same period. Overall, this trial demonstrated a low impact of fertilization on growth dynamics. Water availability was confirmed as the most important factor for poplar growth, in such site, focusing on the importance of studying alternative, less impacting methods for irrigating such crops.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":"44 1","pages":"71-79"},"PeriodicalIF":0.0,"publicationDate":"2020-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43572207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Camaldulensis Dhnh., the most common eucalyptus species in the Mediterranean area, flowers. Its honey yield potential exceeds 200 kg/ha, sometimes accounting for more than 50% of total apiary production. In Italy, eucalyptus plantations cover at least 50,000 hectares, corresponding to a potential production of 10,000 tons of honey per year. Since 2000 several invasive eucalyptus pests have spread and settled in the Mediterranean. Of these, psyllids Blastopsylla occidentalis Taylor and Glycaspis brimblecombei Moore have become major threats to eucalyptus plantations. The main objective of this study was to verify the impact of sap-sucking insects unifloral eucalyptus honey production and quality in Northern Sardinia (Italy). Our results show that a pronounced decrease in honey production occurred after 2011, with no production at all in 2012 and 2013, partial recovery in 2014-2016 and a further increase in 2017 and 2018. Moreover, the incidence of honeydew produced by psyllids has led to modifications in the chemical-physical characteristics and pollen spectrum of unifloral eucalyptus honey.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":"44 1","pages":"66-70"},"PeriodicalIF":0.0,"publicationDate":"2020-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48685206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These plantations usually have a relatively low initial density (250-400 trees ha -1 ) and 1 or 2 thinnings are needed for valuable timber production (75-150 trees ha -1 for final harvesting). Hence, forest managers need to design when to perform the thinnings and how to do it. Analyzing the trees crown area is a very helpful and easy-to-use tool to evaluate the competence between trees and design the thinnings. The present study proposes two statistical models to estimate Crown Diameter (CD) and Crown Competence Factor (CCF) as a function of Diameter at Breast Height (DBH) for hybrid walnut ( Juglans x intermedia ) Mj209xRa planted forests, within a DBH range between 5 cm (min) and 33 cm (max). CD and DBH were measured in 702 trees at the Bosques Naturales SA walnut planted forests in Cuenca, Girona and A Coruna (Spain). The CCF model is a tool to evaluate the Crown Competition Factor as a function of measured DBH in a plantation, and, accordingly, decide if a thinning should be done or not yet and design it.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":"44 1","pages":"24-29"},"PeriodicalIF":0.0,"publicationDate":"2020-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42217968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A statistical analysis (linear model no interaction and PCA) was then performed to evaluate the relative importance of some environmental and management variables for walnut trees in analysed plantations. Results highlighted a variable situation with many different adopted planting schemes across the regions as well as a not standardised spatial layout and management type (thinning). Lower densities and smaller trees were adopted in Italy with about 200 trees ha -1 versus 330 trees ha -1 in Spain. In addition to the age of the plantation as one of the most influencing parameters also the plantation density and the average crown diameter were highly statistically significant.

The objective of the present study is to analyze the effects of different clones in the rooting and acclimation rates for in-vitro micropropagation in hybrid walnut ( Juglans x intermedia Mj 209). The results show a significative effect of clones on the rooting and the total micropropagation efficiency rates, but not on the acclimation rate. The efficiency rate of D-117 (65%) is considered statistically higher than the one for D-15 (38%), caused by a higher rooting rate of D-117 (73%) compared with D-15 (55%), because acclimation rate (57%) did not show any clone effect. Considering these differences in the micropropagation success, it might be considered (together with other factors) for clone selection to increase the general performance of the plant production units in large-scale propagation.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":"44 1","pages":"41-46"},"PeriodicalIF":0.0,"publicationDate":"2020-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41705666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the hybrid progeny Mj209xRa is considered suitable for timber production in Europe, problems associated with its recalcitrance, the low ability for rooting and the high mortality of acclimated vitroplants, limit the reproduction of elite trees. This research was aimed to assess the influence of two methods for the in vitro introduction of several walnut genotypes, to determine the effects of temporary immersion systems (TIS) on proliferation and rooting, and to reduce the random losses of acclimated vitroplants. Hence, trees from Mj209xRa progeny as well as some common walnuts were used. As an outstanding result, the in vitro establishment of 6 out of 7 trees was obtained. Also important was the improving of quality of microshoots, the multiplication ratios and the rooting using TIS through the management of the kind of bioreactor, the volume of culture media, and the kind of explant inoculated. The direct transplant to field nursery of acclimated vitroplants considerably increased their quality, while mortality was highly reduced.
