<正>二十年前的1995年,我当时还在中国茶叶学会办公室工作,上海市茶叶学会来杭举办少儿茶艺夏令营,我有幸接待了这批小茶人。上海市是1992年开始在黄浦区少年宫,首先举办少儿茶艺学习班,经过三年的经历,上海少儿学茶已开始形成一定的规模,在市教委成立了少儿茶艺教研室,许多学校成立了教研组。这次组织少儿茶艺夏令营,到龙井茶的故乡来举行,目的是让孩子们参观和学习茶文化和茶的知识。因此,我带领孩子 相似文献

Crop yield is primarily seed-filling-limited in production system under field conditions.This study was aimed to determine whether seed filling traits of oil flax(Linum usitatissimum L.)could be controlled by phosphorus(P),nitrogen(N),and phosphorus and nitrogen(NP)supply.Effects on seed filling traits were investigated in 2 years including capsule diameter,capsule height,capsule dry matter(DM),seed DM per capsule,pericarp DM per capsule,protein content and oil content.DM translocation from pericarps to seed,translocation efficiency,and contribution of photoassimilates during seed filling period were also detected.In a randomized complete block design,cultivar'Longyaza 1'was grown under P(33 kg P/ha),N(75 kg N/ha),and NP(33 kg P/ha and 75 kg N/ha)along with a zerofertilizer(CK)treatment in 2013 and 2014.Results suggested that DM translocation efficiency and contribution efficiency increased to different extent due to P,N or NP application.At 42 DAA(days after anthesis),seed DM per capsule reached the greatest,while protein content and pericarp DM obtained the least level.However,the highest oil content was detected at 35 DAA.A significant positive linear relationship was observed between seed DM,capsule DM and DM translocation in both years.Protein content showed inconsistent relation with oil content.The results indicated that appropriate N and P management could be an effective approach to increase oil flax production. 相似文献

Foliar fungal diseases(rust and late leaf spot)incur large yield losses,in addition to the deterioration of fodder quality in groundnut worldwide.High oleic acid has emerged as a key market trait in groundnut,as it increases the shelf life of the produce/products in addition to providing health benefits to consumers.Marker-assisted backcrossing(MABC)is the most successful approach to introgressing or pyramiding one or more traits using traitlinked markers.We used MABC to improve three popular Indian cultivars(GJG 9,GG 20,and GJGHPS 1)for foliar disease resistance(FDR)and high oleic acid content.A total of 22 BC3F4 and 30 BC2F4 introgression lines(ILs)for FDR and 46 BC3F4 and 41 BC2F4 ILs for high oleic acid were developed.Recurrent parent genome analysis using the 58 K Axiom_Arachis array identified several lines showing upto 94%of genome recovery among second and third backcross progenies.Phenotyping of these ILs revealed FDR scores comparable to the resistant parent,GPBD 4,and ILs with high(~80%)oleic acid in addition to high genome recovery.These ILs provide further opportunities for pyramiding FDR and high oleic acid in all three genetic backgrounds as well as for conducting multi-location yield trials for further evaluation and release for cultivation in target regions of India. 相似文献

标准化的实验室制作与评价方法是面条品质改良的前提和基础.针对原商业部SB/T10137-93面条制作与品尝评分标准存在的不完善之处,对面条制作过程中的适宜加水量、和面时间、压片和煮面方法进行了研究,制定出我国面条的标准化实验室制作方法与评价系统.具体程序如下:以加水后面团水分含量为35.0%来确定最适宜加水量;通过低速(1 min)、快速(2 min)、低速(2 min)三个搅拌过程完成和面;在压面机上压片八次,并在最后一次压片时切成面条;在等量(2 L)水中用相同时间(6 min)煮等量(150 g)面条,煮面结束立即把面条放入冰水中冷却2 min.改进后的评价系统为色泽15分、外观10分、软硬度20分、粘弹性30分、光滑性15分、食味10分;以雪花粉为对照,将待评样品与对照相比后给出适宜分值.实验结果表明,改进的方法优于SB/T10137-93标准. 相似文献

Rice false smut disease, which is caused by the fungus Ustilaginoidea virens, is currently one of the most devastating rice fungal diseases in the world. Rice false smut disease not only causes severe yield loss and grain quality reduction, but also threatens food safety due to its production of mycotoxins. In this review, the most recent progresses regarding the life cycle, infection processes, genome and genetic diversity, pathogenic gene and disease resistance in rice were summarized in order to provide theoretical basis for the control of U. virens. We also proposed some future directions and key questions that need to be addressed for a better understanding of the molecular mechanism that leads to rice false smut disease and the prospects for sustainable control of rice false smut. 相似文献
