However, the genetic interrelations among species within the genus are not well understood. This study aims to clarify the genetic connections between <i>Michelia compressa</i> (Maxim.) Sarg. (Magnoliaceae) and other species in the genus to probe the potential improvement by interspecific hybridization. The work progresses in three phases: understanding <i>M. compressa</i>’s genetic architecture and its relevance to other <i>Michelia</i> species, identifying natural hybrids among progeny, and developing novel varieties through hybridization. First, the genome from <i>M. compressa</i> was analyzed to confirm its genetic background. The result shows it had 17 pairs of metacentric and 2 pairs of submetacentric chromosomes (2<i>n</i> = 2<i>x</i> = 38, 34m + 4sm), belonging to Stebbins type 2B, which was consistent with the <i>Michelia</i> uniform karyotype formula. Second, transcriptomic data were used to design ten pairs of simple sequence repeat (SSR) primers. The set of ten SSR primers exhibited a high level of polymorphism and were found to be efficient for genotyping. The average number of alleles (Na) per locus was 14.6, with an average expected heterozygosity (He) of 0.860, observed heterozygosity (Ho) of 0.447, and polymorphic information content (PIC) of 0.847. These universal primers were then employed to determine genetic relationships among <i>Michelia</i> species and create SSR fingerprints for 20 Magnoliaceae species. The cluster analysis results revealed that Magnoliaceae was classified into three branches, while <i>Michelia</i> was classified into five branches. <i>M. compressa</i> exhibits a close phylogenetic relationship with both <i>M. maudiae</i> and <i>M. cavaleriei</i> var. <i>platypetala</i>. Third, according to the fingerprinting information, all 19 progeny from open-pollinated <i>M. compressa</i>, i.e., <i>M.</i> ‘Zhongshanhanxiao’, were confirmed to be true hybrids resulting from natural crosses. The putative progenitors of <i>M</i>. ‘Zhongshanhanxiao’ are believed to be <i>M. maudiae</i> and <i>M. cavaleriei</i> var. <i>platypetala</i>. <i>M. compressa</i> demonstrates a significant hybrid affinity with both <i>M. maudiae</i> and <i>M. cavaleriei</i> var. <i>platypetala</i>. The SSR primers developed were used to identify hybrids, particularly in the <i>M. compressa</i> × <i>M. maudiae</i> and <i>M. compressa</i> × <i>M. cavaleriei</i> var<i>. platypetala</i> combinations, where a substantial proportion of true hybrids were found. Further analysis suggests that the probable progenitors of <i>M</i>. ‘Zhongshanhanxiao’ are either <i>M. maudiae</i> or <i>M. cavaleriei</i> var. <i>platypetala</i>.

Management and restoration plans are therefore needed. To contribute with local knowledge of the species, we studied the diversity of flower visitors of both species in 9 sites in Napo Province during the flowering seasons of 2021 and 2022.

We conducted a study in French Guiana, screening BVOC emissions from 36 tropical woody species. We focused on 32 species in the dry season and 33 in the wet season, documenting terpene emissions for the first time in some of these tree species. Our findings show that 93.8% emitted terpenes in the dry season, while only 33.3% did so in the wet season. Terpene emissions ranged from 0.01 to 80.9 μg g⁻¹ h⁻¹ in the dry season and 0 to 11.7 μg g⁻¹ h⁻¹ in the wet season, consistent with previous reports. We identified and quantified 23 terpene compounds, including 19 monoterpenes and 4 sesquiterpenes. Additionally, 2 non-terpenoid compounds were detected: 2,2,4,6,6-pentamethylheptane (with no detected emissions in the dry season) and toluene. Among the monoterpenes, the most abundant were α-terpinolene, limonene, α-pinene, β-ocimene, and sabinene. As for sesquiterpenes, β-caryophyllene, α-caryophyllene, and α-copaene were observed during the dry season, while during the wet season, α-terpinolene predominated, followed by limonene, α-pinene, sabinene, β-caryophyllene, and α-copaene. Isoprene was detected in most of the species studied in both seasons. Sesquiterpene emissions displayed a notable phylogenetic pattern, whereas total terpenes and monoterpenes did not; however, total terpenes and monoterpenes exhibited a significant seasonal influence. Our study demonstrates that seasonality strongly influences BVOC production in tropical trees, with higher emissions in the dry season. These findings imply that various factors and conditions influence tree emissions in this tropical forest, affecting their ecological, environmental, and climatic roles, as well as the implementation of atmospheric chemistry models.</p></div>","PeriodicalId":805,"journal":{"name":"Trees","volume":"38 4","pages":"997 - 1012"},"PeriodicalIF":2.1,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141511632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used samples collected during dendrochronological studies to measure bark thickness and data from old-growth attribute surveys to assess the occurrence of trunk cavities (or hollows) associated with heartwood decay. First, nonlinear mixed-effects models were calibrated to predict bark thickness. Then the probability of hollow occurrence was evaluated with binomial regression using generalized linear models. Bark thickness increased with tree size, attaining an asymptote of 11.9 cm. This finding suggests that thickness above the asymptote may not offer additional protection to trees. Because bark has an influence on allometry assessments, we provide an accurate model to improve wood volume estimates. Hollows are associated with tree size and affect mechanical stability, and due to their empty space, it can cause bias in allometry assessment of biomass and wood volume. Suitable predictors of the probability of tree decay or vitality are provided. The predictors evaluated can also be used as a tree-level indicator of quality in selection systems.
