Pepper Breeding

This study was designed to assess the androgenic potential of 180 pepper accessions and 11 progenies (four F1 and seven BC) possessing PMMoV resistance in order to complement an ongoing pepper breeding program. The experiment was carried out in 10 replications with 20 anthers for each accession in two different induction mediums from 2017 to 2019. The highest androgenic response was observed in culture medium 17-2 but differences between two mediums were nonsignificant. From a total of 191 genotypes, 102 genotypes expressed a potential for direct embryogenesis. Embryo induction was seen to be genotype-dependent and decreased in the following order: Pumpkin > Conical > Bell or blocky > Round > Elongate as the most responsive genotypes with over 10% reacted anthers being observed in CAPS-23, CAPS-29, CAPS-127, CAPS-157, CAPS-169, F1 and BC 887 derived from CAPS-23. The number of regenerated plants was higher in the conical group and least in the round varietal group. Regenerated plants were examined visually and by flow cytometry for identification of spontaneous doubled haploids (DH) and haploids. Those originating from F1 and BC progenies were additionally evaluated by a CAPS marker targeting L4 allele for resistance against PMMoV. Obtained results revealed two groups consisting of homozygous susceptible and resistant plants. Therefore, use of anther culture in ongoing breeding will greatly facilitate the pepper genetic improvement.

Introduction : Le syndrome d’apnées obstructives du sommeil (SAOS) est une affection très répandue et insuffisamment diagnostiquée, ce qui en fait un problème majeur de santé publique et de sécurité. La rééducation myofonctionnelle orofaciale (RMO) a été montrée efficace dans le traitement multidisciplinaire des SAOS de l’enfant, de l’adolescent et de l’adulte et elle est prescrite à plusieurs étapes de ces prises en charge. Objectifs : L’objectif principal de cette revue systématique de la littérature était d’évaluer l’efficacité de la rééducation myofonctionnelle orofaciale (RMO), active ou passive, dans le traitement du syndrome d’apnées obstructives du sommeil chez les enfants, les adolescents et les adultes. Matériel et méthodes : La revue systématique de la littérature fut entreprise à partir des trois bases de données électroniques : Medline (via PubMed),Cochrane Library, Web of Science Core Collection, et complétée par une recherche limitée de la littérature grise (Google Scholar) afin d’identifier les études évaluant l’efficacité de la RMO sur le SAOS. Le critère de jugement principal était une diminution de l’indice d’apnées/hypopnées (IHA) d’au moins cinq épisodes par heure par rapport à l’état initial. Les critères de jugement secondaires étaient une amélioration de la qualité subjective du sommeil, de la qualité du sommeil mesurée par polysomnographie nocturne et de la qualité de vie mesurée subjectivement. Résultats : Seulement dix études répondaient à tous les critères d’inclusion. Huit étaient des essais cliniques contrôlés randomisés, une était une étude de cohorte prospective et une autre était une étude de cohorte rétrospective. Six études étaient consacrées au SAOS de l’adulte et quatre au SAOS pédiatrique. Toutes les études incluses ont été évaluées à « faible risque de biais » d’après les douze critères de risque de biais du Cochrane Back Review Group. D’après les données probantes disponibles, la RMO permet une réduction significative de l’IAH, jusqu’à 90,6 % chez l’enfant et jusqu’à 92,06 % chez l’adulte. Elle permet une diminution significative de l’intensité et de la fréquence du ronflement, participe à une réduction de la somnolence diurne, limite la réapparition des symptômes d’apnée obstructive du sommeil (AOS) après adénoamygdalectomie chez l’enfant et améliore l’adhésion au traitement par ventilation en pression positive continue (PPC). La RMO passive, avec l’assistance apportée au patient par le port d’une orthèse sur mesure à bille, augmente l’observance à la rééducation, permet une réduction significative de l’intensité du ronflement, de l’IAH et un accroissement significatif des voies aérifères supérieures. Conclusions : Les données publiées montrent que la rééducation myofonctionnelle orofaciale est efficace dans les traitements multidisciplinaires des SAOS de l’enfant, de l’adolescent et de l’adulte et devrait être largement prescrite à plusieurs étapes de ces prises en charge. La RMO passive, avec l’orthèse d’avancée mandibulaire à bille conçue par Michèle Hervy-Auboiron, aide à pallier les fréquents défauts d’observance observés lors des traitements par RMO active.

Strawberry Cultivars

Twelve strawberry cultivars established in matted row plots in 1993 were treated with insecticides for tarnished plant bug or left untreated for the 1994, 1995, and 1996 seasons. `Honeoye', `Cavendish', and `Oka' had the highest yields of marketable fruit. `Jewel', `Chambly', and `Kent' had lower, but acceptable, yields. `Lateglow', `Blomidon', `Seneca, NY1424', `Settler', and `Governor Simcoe' had lower yields than other varieties. Tarnished plant bug populations were very low during the 1994 and 1996 seasons, and thus feeding pressure may have been too low for any differences in susceptibility between varieties to be expressed. In 1995, when tarnished plant bug feeding pressure was greatest, `Oka', `Cavendish', and `Honeoye' had the lowest injury levels. `Kent' and `Lateglow' had the highest levels of injury. Insecticide sprays significantly reduced the percent of injured fruit for most cultivars, but did not significantly increase the weight of marketable fruit harvested. This is due to injury being most prevalent on lower order, and thus smaller, fruit. Cultivars that produced high yields, had low injury levels, and had the least difference between sprayed and unsprayed treatments are most likely to have resistance to tarnished plant bug injury. `Oka', `Cavendish', and `Honeoye' were the most promising cultivars in this regard.

Strawberry Cultivars

Volatile compounds principally contribute to flavor of strawberry (Fragaria × ananassa) fruit. Besides to genetics, cultivation conditions play an important role in fruit volatile formation. Compared to soil culture as control, effects of substrate culture on volatile compounds of two strawberry cultivars (‘Amaou’ and ‘Yuexin’) were investigated. GC-MS analysis revealed significant difference in volatile contents of ‘Amaou’ strawberry caused by substrate culture. No significant effect was observed for cultivar ‘Yuexin’. For ‘Amaou’ strawberry from soil culture produced higher volatile contents compared with substrate culture. This difference is contributed by high contents of esters, lactones, ketones, aldehydes, terpenes, hydrocarbons, acids, furans and phenols in ‘Amaou’ strawberry fruit from soil culture. Furanones, beta-linalool, trans-Nerolidol and esters are major contributor to strawberry aroma, whose contents are higher in soil culture planted fruit when compared to substrate culture. Moreover, strawberry fruit from soil culture had higher transcripts related to volatile biosynthesis were observed, including FaQR, FaOMT, FaNES1, FaSAAT and FaAAT2.

Strawberry Cultivars

Strawberry (Fragaria×ananassa Duch.) production requires the input of large amounts of water provided by irrigation during the entire production cycle. However, water availability is shrinking in many important strawberry cropping areas, such as Huelva (in Europe), compromising the environmental sustainability and economic viability of strawberry production. Besides technical approaches, water-saving strategies are necessary for improving strawberry water productivity such as the use of low water-consumptive cultivars with high productivity or cultivars allowing deficit irrigation (DI) strategies. A two-year field experiment was conducted to compare the physiological and agronomical response of six commercial strawberry cultivars (‘Sabrina’, ‘Fortuna’, ‘Splendor’, ‘Primoris’, ‘Rabida’ and ‘Rociera’) to six different water treatments ranging from 65% to 140% of estimated ‘Sabrina’ evapotranspiration (ETcSab; ~224–510 mm year−1). Cultivars differed substantially in yield and water consumption linked to their biomass partitioning into reproductive/ vegetative organs, determining different yield efficiency (YE). Their water needs (IN) conditioned their response to different water supplies, involving significant yield losses in DI treatments (<20% IN) but not decreasing fruit quality. The highly-consumptive and productive ‘Rabida’ and ‘Rociera’, reduced yields by DI (<40%) but were still profitable; the low-water-consumptive but still productive ‘Fortuna’, ‘Splendor’ and ‘Primoris’ represent significant water-savings (<20%) in strawberry cultivation.

Governance Models

Cruise activities, until 2020, have presented a significant increase in revenue, as well as number of cruises and passengers transported, and it has become a challenge for ports to respond to this demand for services. In response to this, the world’s ports have implemented different governance models. In this context, in this paper, we aim to review the different governance models, as well as port cooperation, competition, and stakeholders. For this purpose, using science metric meta-analysis, an article set is extracted that strictly refers to the governance model of two databases integrated into the Core Collection Web of Science, whose selection process is polished with the PRISMA guidelines, establishing the eligibility criteria of studies using PICOS tool, to which a qualitative meta-analysis is applied. A limited studies set is identified, that includes governance model implementations, private strategies and internalization patterns in the port sector and cruise ships, patterns of port cooperation and governance, governance models in cruise ports, structures and strategies, and changes in the cruise market. Finally, various governance model forms are determined, all documented in the scientific research worldwide, discussing the various components of study topics.
