从学堂乐歌与传统的关系看中国传统音乐的传承与发展

音乐艺术和其他文化一样，有着极强的传承性和延续性以及民族性。本文从学堂乐歌的发展，分析中国传统音乐的认识及发展，指出继承和发扬中国传统音乐文化必须解决好纵向继承优秀民族传统音乐文化和横向借鉴优秀外国音乐文化的主题。     

Comparative mapping of rice root traits in seedlings grown in nutrient or non-nutrient solution

The component and amount of nutrient in the growth medium are the major factors affecting root growth.For the systematic dissection of root gene expression,evaluation of nutrient and non-nutrient solutions was conducted for their effect on root traits and quantitative trait loci(QTL)mapping.Three rice root parameters,maximum root length(MRL),root dry weight(RDW),and root/ shoot ratio of dry weight(RSR),were characterized within a double haploid(DH)population from a cross of ZYQ8(indica)and JX17(japonica).The value of the three root traits in two parents all decreased under the nutrient condition compared to those under the nonnutrient condition,of which RSR decreased up to 2.6-fold on average.In the DH population,more than 70 % lines in MRL,94 % lines in RDW,and all the lines in RSR were scored lower.In total,eight QTLs were identified in nutrient system(5 from JX17 alleles and 3 from ZYQ8 alleles)while five QTLs were detected in non-nutrient system(4 from JX17 alleles and 1 from ZYQ8 alleles).Of them,one QTL for RSR was shared by both culturing systems,seven QTLs were specific in nutrient system and the other four QTLs were specific in non-nutrient system.All 13 QTLs were distributed over 7 rice chromosomes-2,3,4,5,6,9 and 10,respectively.     

Low temperature wheat germplasm and its leaf photosynthetic traits and structure characteristics

Low temperature germplasm with constant low plant temperature was found in the nature through a long-time observation on wheat canopy temperature and traits; correspondingly, high temperature germplasm with constant high plant temperature also exists. Compared with the high temperature germplasm, the chlorophyll content and the net photosynthetic rate of the three functional leaves on the top of the low temperature wheat germplasm are higher and the structure tends to be more complicated, which is characterized by smaller mesophyll cells and more closely arranged cell layers, more and denser chloroplasts with thick stroma, more granas and well developed grana lamellae, a larger vascular bundle area with smaller interspace. All these characteristics embody the consistency of structure and function and provide the theoretical bases for looking for and cultivating the new low temperature materials in agricultural practice.     

玉米若干与抗旱性有关的产量性状遗传研究

按NCII设计,分析了15个玉米自交系与抗旱性有关的穗长、结实长、穗行数、行粒数、百粒重和单株产量等产量性状在中等水分胁迫下的GCA、SCA和遗传力.结果表明:3个优良自交系80660,80009,武109能组配出抗旱高产且产量性状良好的杂交组合,是有利用价值的亲本;80625×武109、80009×138、80622×武109等组合可在干旱与半干旱地区示范种植.在水分胁迫下,产量遗传力较低,寻找遗传力高且与产量和抗旱高度相关的第二类性状穗长、结实长、穗行数、行粒数,在早代进行选择,可提高选择效率.     

JA_3保鲜刺梨的研究

天然食品添加剂──ＪＡ３作保鲜剂对鲜刺梨果进行涂膜处理后于室温下贮藏，分别对利梨进行了失重、感官和Ｖｃ含量的检测，证明采用０．３％ＪＡ３涂膜液对刺梨有较好的保鲜效果。在刺梨保鲜剂中优于用海藻酸钠和蔗糖脂肪酸组成的保鲜剂。     

二棱大麦数量性状相关遗传力和选择指数分析

以15个二棱大麦品种(系)为材料,用相关遗传力研究大麦数量性状的相关遗传,并计算分析籽粒产量和产量构成性状所组合的各种选择指数。结果表明:各性状与单株粒重的相关遗传力均低于单株粒重的遗传力,因而仅利用一个性状作间接选择的效率比对单株粒重作直接选择的效率低,在构成大麦产量的三要素中,着重提高单株穗数对产量的选择效率为最大;高产育种同时考虑与产量显著相关的性状比单纯对产量选择的效果好,其中以单株穗数、每穗粒数和籽粒产量结合起来选择的效果最佳。本文并对相关遗传力在相关遗传变异分析中的应用进行了讨论。     

光谱峰面积技术在光度法测定食品微量铁含量中的应用

在邻二氮菲光度法的基础上,引入光谱峰面积技术,对微量铁进行定量测定,该方法避免了有关离子的干扰,提高了准确度.对于面粉、奶粉和肝等食品样品进行分析,结果令人满意.     

《水浒传》说话艺术研究

依据中国古典美学与审美传统,通过对《水浒传》情节模式特色、情节结构特色、情节叙述特色三个方面的分析,力图阐释《水浒传》所具有的为情节而艺术与为艺术而情节的说话艺术特色。     

青海省新型甘蓝型油菜品系主要性状研究
