“…Serbia cultivates hazelnuts on approximately 2.200 ha and produces about 800-1000 t, which is actually not enough to meet local demands [3]. There is a growing interest in domestic hazelnut production because of favorable agricultural conditions, but it should be supported by the adequate choice of cultivars with long period of investments and incoming yield from fifth until eighth years of cultivation [4]. Hazelnut cultivars in Serbia come from the European hazelnut (Corylus avellana L.) and are mostly grown in Vojvodina, in the north of Serbia.…”

The present study evaluates natural composition of Serbian roasted hazelnut skins (HS) with potential role in application as functional nutrient of various food products. Total phenols (TPC) and flavonoids contents (TFC) in HS extracts obtained with different ethanol concentrations (10%—I, 50%—II and 96%—III) and their antioxidant activities were investigated. The highest total phenols content (706.0 ± 9.7 mgGAE/gextract) was observed in 96% ethanol HS extract. Ethanol HS extracts showed very high antioxidant activity with effective concentrations (EC50) ranged between 0.052 and 0.066 mg/mL. The phenol and flavonoid content of roasted HS extracts I–III was determined by HPLC-ESI-MS/MS analyses. Contents of lipids, proteins, carbohydrates, metals, and C, H, N, S elements in roasted HS were also determined. Relatively high C/N, C/P and C/N/P ratios, rich metal contents and fatty acids composition indicated that hazelnut skin might be a good candidate for use as either human or fungal functional nutrient. In addition, possible application of phenolic HS extracts as UV booster was studied by recording UV spectra (220–440 nm) of 10 mg/L of HS extracts I–III combined with 10 mg/L of chemical sunscreen agent benzophenone-3 and in vitro sun protection factor (SPF) was calculated.

“…The ribosomal ITS region is recognized as a universal marker for the identification of fungi 17 . Polymorphisms in both length and sequence, the availability of databases to compare sequences, universal primers and a high rate of successful amplification among all fungal lineages are some of the reasons why this marker has been recognized as a good outlet for the identification of endophytic fungi 8,9,17,18 .…”

Pine is one of the important coniferous genera in America. In Honduras, Pinus oocarpa is the most critical conifer species since it plays an essential role for the country's economy and represents a symbol of national identity. Endophytic fungi are defined as microorganisms that reside in the internal tissues of plants without causing any obvious immediate negative effects and are an integral part of their associated microbial communities. This study aimed to isolate and characterize the endophytic fungi present in the pines of Honduras through the amplification and sequencing of the ribosomal RNA gene's internal transcribed spacer (ITS). A total of 7 pines from the department of El Paraíso in eastern Honduras were analyzed. A total of 14 fungi grouped into 6 genera and 7 species were isolated: Fusarium lateritium, F. pseudocircinatum, Pestalotiopsis pini, P. microspora, Xylaria grammica, Trichoderma atroviride, y Nigrospora oryzae. To our knowledge, this is the first report of endophytic fungal species in pines in Honduras. Although some endophytic fungi may be mutualistic or saprophytic, the present study shows the presence of several genera of endophytic fungi that have been reported as pine pathogens. The presence of these fungi in the pines of Honduras represents a potential threat to the health of the forest. Further research is needed to increase knowledge about the importance of these fungi and the potential impact they could have on pine forests in Honduras. Keywords: Endophytic fungi, Pinus oocarpa, Honduras

“…Shape, color and edge of colony, size and shape of conidia of each pathogen, size and shape of appressoria of C. gloeosporiodes were recorded by using Leica LAS EZ imaging software with Leica DM500 optical microscope. The morphological characteristics were described according to (Sawant et al, 2012;Vasić et al, 2017).…”

Guava fruits are subjected to infect by several plant pathogens derange the storage as a post-harvest diseases. Anthracnose is one of the most prevalent fruit rot diseases. This study focused on pathogens of anthracnose, which infected guava fruits at post-harvest. Pathogenicity, host range, morphological and physiological characteristics were studied. Colletotrichum gloeosporiodes, and Pestalotiopsis psidii were isolated from guava fruits. Clementina cv was more susceptible to P. psidii and C. gloeosporiodes infection, while pepper, cucumber, and zucchini fruits were resistant to P. psidii. Navel orange and beans are less susceptible to infect by C. gloeosporiodes. The temperature from 25-30°C was the optimum degree for the growth of C. gloeosporiodes, while the temperature from 30-35°C was optimum for P. psidii. The appropriate pH for all fungi under study was 6.5, followed by 6 pH. PDA was the appropriate solid medium for the growth of C. gloeosporiodes, while Richard ' s Agar was the most favored for growth of P. psidii.
