An additional aim is to provide a complementary technique for analysis of the traits and orientation of breeding programs of biomass sorghum through data mining. A total of 25 hybrids of biomass sorghum were evaluated in a triple square lattice design. The following traits were measured: flowering (FLOW); plant height (PH); fresh biomass yield of the stalk (FBYs), of leaves, and of panicles; dry matter of the stalk and of the leaves (DMl); neutral detergent fiber of the stalk and of the leaves; acid detergent fiber of the stalk and of the leaves; lignin of the stalk and of the leaves; hemicellulose of the stalk and of the leaves; cellulose concentration of the stalk and of the leaves; and the TCV. The data were placed under exploratory analysis, the mixed model approach, pathway analysis based on genotypic correlations, and the regression tree technique. The traits FLOW, PH, FBYs, DMl, and LIG were considered the main determinants of the changes in the TCV and, therefore, with potential for use in indirect selection. The technique of data mining allowed better visualization of the relationships among the traits, assisting in some explanations regarding the effect of the traits on the TCV.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"26 6","pages":"1640 - 1652"},"PeriodicalIF":1.8,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551955","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}

To determine the specific expression of the NAC transcription factor family in different organs of sugar beet under different abiotic stress conditions, this study systematically analyzed the expression response of 52 members of the NAC transcription factor family in different organs to abiotic stress conditions using reverse transcription polymerase chain reaction technique. The responses of NAC transcription factor genes to different abiotic stresses were identified in sugar beet leaves and roots; 18 and 17 NAC transcription factor genes were found to respond specifically to abiotic stress in sugar beet leaves and roots, respectively.

In the present study, the carbon emissions generated in sugarcane planting process were measured, and the green production efficiency along with comprehensive social development of main sugarcane-producing areas was evaluated and coupled to assess the coordination. The results indicated that carbon emission intensity from sugarcane planting in China decreased from 3.0963 tons/ha in 2012 to 2.4863 tons/ha in 2021, a decrease of 19.70%. The green development efficiency has significantly improved, rising from 0.9228 in 2012 to 1.1478 in 2021. The efficiency in Guangdong and Hainan reached its peak in 2021. Notably, the degree of coupling and coordination between green sugarcane production and comprehensive social development has progressively improved, transitioning from low- to high-level coupling and from serious imbalance to high-quality coordination. In 2021, all regions achieved a high degree of coupling and high-quality coordination. Collectively, reduced application policies in China, accompanied by the development of agricultural technology, have led to a progressive decline in carbon emissions from sugarcane planting while simultaneously improving green production efficiency. Besides, a state of mutual promotion and high-quality coordination was observed in green sugarcane production and local comprehensive social development. This study advances the theoretical framework of carbon emissions and offers empirical evidence for the ecological and economic significance of sugar industry.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"26 4","pages":"1134 - 1146"},"PeriodicalIF":1.8,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551956","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}

The present research examined the ecological consequences of sugar beet cultivation in two distinct systems, involving both agro-industries (AIs) and smallholder farmers (SHs), focusing on the Moghan and Joveyn regions, prominent sugar beet production areas in Iran. The study utilized the IMPACT World + life cycle assessment method to evaluate harmful impacts at midpoint and damage levels. Additionally, potential harms were identified within two area of protection (AoPs) categories: human health and ecosystem quality, and two area of concerns (AoCs) categories: carbon-related and water-related damages. The findings revealed that in terms of AoPs, AIs had 0.44% and 4.32% higher impacts on human health than SHs in the Moghan and Joveyn regions, respectively. Additionally, AIs showed 7.97% and 21.44% higher impacts on ecosystem quality compared to SHs in the same regions. Water-related impacts significantly contributed to over 90% of the total environmental impacts in both AoPs.
