A new PAT application: Optimization of processing methods for honeysuckle flower (Lonicerae Japonicae Flos) and wild honeysuckle flower (Lonicerae Flos)

Objective:A novel processing analytical framework of Chinese Material Medica (CMM) includes breeding process analysis,planting process analysis,producing process analysis and manufacture process analysis.In order to study this framework,we used quality control of honeysuckle flower (Lonicerae japonicae Flos) including diploid and tetraploid Lonicera japonica,and wild honeysuckle flower (Lonicerae Flos) including Lonicerae hypoglauca,Lonicerae confusa,Lonicerae fulvotomentosa and Lonicerae macranthoides as an example.Methods:A total of 360 samples were analyzed from three variables including species,growing areas,and optimization of processing methods.For quantitative analysis,chlorogenic acid (CA),isochlorogenic acid A (3,5-DCA),and isochlorogenic acid C (4,5-DCA) were measured with high performance liquid chromatography (HPLC).Results:The three organic acids contents are higher in wild honeysuckle flower than honeysuckle flower;L.japonica (tetraploid) is higher than L.japonica (diploid).Modern processing methods (kill-enzyme torrefaction and fixing machine drying) are popular in growing areas and are superior to traditional methods (sun and shade drying).Conclusions:Novel process analysis concepts in processing analytical technology (PAT) enriched the Chinese MateHal Medica contents.

An overview of the endogenous and environmental factors related to the Coffea arabica flowering process

The transition of vegetative meristems to a reproductive state followed by floral development and flowering is a complex process regulated by many regulatory pathways that integrate(epi)genetic and environmental factors to guarantee the reproductive success in angiosperms.In woody and perennial species,such as coffee trees,the extended life cycle reflects adaptive strategies,i.e.,two-year cycle,sequential flowering and bud latency during the winter,that ensure reproductive success in a variable environment.The dynamics of coffee flowering integrate multiple stimuli to induce morpho-physiological changes,especially during the reproductive phase.We discussed diverse stimuli which are directly and indirectly associated with molecular pathways related to the reproductive meristem transition and floral development until anthesis.Here,we propose to redefine some concepts regarding coffee floral development,such as:i)a summary of genes possibly involved in the flowering pathways;ii)a new classification of buds by position in the node(B1-B4)to avoid misunderstandings with the uneven developmental stages;iii)comparative ABC model to Arabidopsis and tomato to allow evolutionary discussions of whorls development in Coffea sp.From this,we expect to collaborate to drive future studies towards coffee breeding and production,for example,improving floral bud activation,controlling the flowering time,anthesis synchronization to produce more homogeneous ripening fruits,reducing abortion or early flower openings,and increasing fruitification.Moreover,we think that the explored relationship between physiological and molecular approaches during the coffee flowering may be extended to understand other tropical perennial species,especially those with asynchronous flowering behavior,and to understand evolutive aspects in Rubiaceae.

基于改进YOLOv8-Seg的苹果单枝条花序疏除方法

针对苹果疏花作业中无法自动识别枝干以及缺乏花序疏除方法,该研究提出了一种适用于现代果园的苹果树单枝条花序疏除方法。首先,对YOLOv8-Seg模型进行改进:在Backbone部分添加GCT(Gaussian context transformer)模块,通过引入全局上下文信息和调整通道的重要性,提高模型对遮挡目标的分割性能;在对应3个检测头的Neck部分的C2f模块内部增加EMA(efficient multi-scale attention)机制,通过并行子网结构和跨空间信息聚合更好地关注多尺度特征。其次,使用改进YOLOv8-Seg模型对单枝条中的花苞、花序、开放花朵和花枝四类目标进行实例分割。最后,基于分割结果应用多项式拟合曲线表征花枝,并计算花序间距离实现花序疏除。结果表明,改进的YOLOv8s-Seg模型在自建数据集mask水平的精确率、召回率和mAP分别达到了89.9%、89.5%和91%,比原模型分别提升了6.5、4.1和5.8个百分点。与主流分割模型Mask R-CNN,YOLACT,SOLOv2进行对比,mask水平的mAP分别高出10.8、12.3和9.1个百分点。花序疏除决策结果与人工决策结果对比误差不超过10%。该方法可应用于单枝条水平上的花序疏除任务,为苹果智能疏花提供技术支持。
