Quality and yield are the primary concerns in kiwifruit breeding,but research on the genetic mechanisms of fruit size,shape,and ascorbic acid(ASA)content is currently very limited,which restricts the development of kiwifruit molecular *** this study,we obtained a total of 8.88 million highly reliable single nucleotide polymorphism(SNP)markers from 140 individuals from the natural hybrid offspring of Actinidia eriantha cv.‘White’using whole genome resequencing technology.A genome-wide association study was conducted on eight key agronomic traits,including single fruit weight,fruit shape,ASA content,and the number of inflorescences per branch.A total of 59 genetic loci containing potential functional genes were located,and candidate genes related to single fruit weight,fruit length,ASA content,number of inflorescences per branch and other traits were identified within the candidate interval,such as AeWUSCHEL,AeCDK1(cell cycle dependent kinase),AeAO1(ascorbic oxidase)and AeCO1(CONSTANS-like 4).After constructing an RNAi vector for AeAO1 and injecting it into the fruit of cv.‘Midao 31’to interfere with the expression of the AeAO1 gene,the results showed that the activity of ascorbic oxidase in the fruit of‘Midao 31’significantly decreased,while the content of ASA significantly *** study provides valuable insights into the genetic basis of variation in *** fruit traits,which may benefit molecular marker-assisted breeding efforts.

农村人力资源开发是实现剩余劳动力转移的根本途径。分析了天津农村人力资源的现状,指出存在着农村耕地连年减少,农业产业结构调整带来的农村剩余劳动力数量的增加、就业面狭窄、农民增收缓慢等新问题,认为农村人力资源开发的意义和作用在于促进农村剩余劳动力转移,提高劳动力素质,从而从根本上解决"三农"问题。由此提出其主要对策是增强农村职业教育办学活力,充分挖掘农业内部就业潜力及构建天津特色的农民终身教育体系,建立健全农民职业教育和农村剩余劳动力就业培训机制及有效管理机制,加快开发农村人力资源。

农户绿色生产行为是顺应农业绿色发展的必然要求。本文采用数据包络分析(DEA)及倾向得分匹配法(PSM),选取860份赤峰市中药材种植农户微观调研数据,基于农户分化视角探讨中药材种植农户绿色生产行为生产绩效差异问题。结果表明:首先,中药材种植农户实施绿色生产行为有助于生产绩效的提升,但不同类型中药材种植农户间存在差异,其全样本平均生产绩效为0.75,生存型农户最低,为0.65,生产型农户最高,为0.82.生活型农户和功能型农户较为接近,分别为0.80和0.79;其次,从平均处理效应(ATT)计算结果看,中药材种植农户实施绿色生产行为可以增加生产绩效、总产量和总产值;再次,绿色生产行为对不同类型中药材种植农户生产绩效的提升作用存在群体差异,其中生存型、生活型农户实施绿色生产行为对生产绩效影响不显著,功能型、生产型农户则具有显著影响,但生产型农户呈现负向影响。因此,要强化农户绿色生产行为实施力度,提高不同类型中药材种植农户绿色生产意识。另外应保护传统意义上的生存型和生活型农户,强化生产型农户的减施力度,培育功能型农户群体规模,推动社会福利改善,进而促进中药材产业绿色健康发展。
