| 1 | 红小豆花器官脱落对短日照诱导的生理响应显示文摘以中晚熟红小豆品种冀红4号为材料,于2010-2011年在河北农业大学农业气象实验站,设置10、12和14h光照3种短日照处理,以自然光周期处理作为对照(CK),从对生真叶出土开始进行短日照处理,至各处理始花期为止,观测不同处理的生育进程,花的形成和脱落,植株不同节位花的纤维素酶活性、多聚半乳糖醛酸酶活性、过氧化物酶(POD)活性、超氧化物歧化酶(SOD)活性,以及全氮、全磷、全钾含量和C/N。结果表明,短日照处理可使红小豆始花期和终花期均提前,其中10h短日照处理促进作用最明显;在中下部至中上部植株的各节位,12h短日照处理落花数和比例均最低,且在该部位,12h短日照处理的花中纤维素酶活性、多聚半乳糖活性、过氧化物酶活性和超氧化物歧化酶活性均明显低于其他处理;在植株中部到中上部的各节位中,12h短日照处理红小豆植株花中全氮、全磷和全钾含量都明显高于其他处理。另外,12h短日照处理红小豆植株花中C/N明显低于其他处理。 | 尹宝重 刘盼 张月辰 | 2015 | 作物杂志2015，，1： | 4 |
| 2 | 小豆种质资源花期叶绿素含量及与农艺性状相关性分析显示文摘【目的】分析小豆花期叶绿素含量的变化规律及其与产量等农艺性状的相关性,以了解小豆叶绿素含量的驯化选择变异和与生育期及产量的关系。【方法】利用SPAD-502PLUS便携式手持叶绿素仪,测定相对叶绿素含量。【结果】不同小豆材料始花期开始14d内,相对叶绿素含量不断升高,栽培小豆种质资源的相对叶绿素含量显著高于野生小豆和半野生小豆。栽培小豆相对叶绿素含量与百粒重、种子长和种子宽呈极显著正相关,与最大叶长显著正相关,与生育期呈极显著负相关;野生小豆相对叶绿素含量与生育期、单株产量和种子宽呈极显著正相关,与最大叶宽呈显著正相关。【结论】从野生小豆到栽培小豆驯化进程中,相对叶绿素含量向上选择。栽培小豆相对叶绿素含量增加,与百粒重、种子长和种子宽增加趋同;野生小豆相对叶绿素含量增加,促进单株荚数、单荚粒色和单株产量增加。 | 王天奇 赵波 李奕松 刘靖崧 侯亚楠 杨凯 万平 | 2018 | 北京农学院学报2018，33，4： | 3 |
| 3 | 不同施肥比例对无患子生长和养分分配的影响显示文摘选择优质无患子幼苗为试验材料,氮肥设置0(CK)、4、6、10、14 g/株,按氮(N)、磷(P)、钾(K)(质量比为4∶3∶2)设定4个不同施肥比例处理,探讨不同N、P、K比例施肥对温室盆栽无患子生长及养分分配的影响。结果表明:(1)随着施肥量的增加,无患子幼苗的苗高、地径和生物量均呈现先升高后降低的变化趋势,8月和9月无患子幼苗的苗高、地径以及总生物量均在T2处理时达到较大值。(2)不同施肥比例显著提高了无患子幼苗的N、P、K含量。在生长季前期和中期无患子幼苗各组织器官的N、P含量表现为叶>茎>根,而各组织器官K含量表现为茎>根>叶,在生长季末期叶片中的N、P、K含量明显降低,幼苗茎、根中的N、P、K含量提高。综上所述,无患子幼苗在施肥管理中应注重N、P、K复合肥配施。 | 连人豪 | 2020 | 江苏农业科学2020，48，13： | 3 |
| 4 | Photosynthetic performance of switchgrass and its relation to field productivity:A three-year experimental appraisal in semiarid Loess Plateau显示文摘To reveal photosynthetic characteristics and biomass yield is important for evaluating introduced species adaptation to local environments. A field experiment was conducted over three consecutive years(2011–2013) to evaluate photosynthetic characteristics, soil water content, aboveground biomass accumulation, and water use efficiency(WUE) in switchgrass(Panicum virgatum L.) populations exposed to three row spacing(20, 40 and 60 cm) treatments in two growth months(June and August) on the semiarid Loess Plateau of China. Results indicated that net photosynthetic rate(P_n), transpiration rate(T_r), instantaneous water use efficiency(WUEi) and plant height of switchgrass showed an increased trend, but aboveground biomass production and WUE showed an decreased trend with enlarged row spacings over the three years. The maximum daily mean Pn values(17.9, 18.4 and 19.7 μmol CO_2 m^(-2) s^(-1)) were observed in 2011, and the highest aboveground biomass production(67 771.8, 6 976.8 and 6 609.2 kg ha^(-1)) were recorded in 2012 for 20, 40 and 60 cm, respectively. A close correlation between tiller numbers and aboveground biomass production(r=0.907) was observed. Pn was positively and significantly correlated with biomass per tiller, but it showed a negative correlation with aboveground biomass production. Our results confirm that wide row spacing is beneficial for single plant development, while narrow row spacing favors biomass production and water use of switchgrass in the region. It also implies that single leaf growth and performance could explain the switchgrass community density differences, while fails to account for the aboveground biomass production. | GAO Zhi-juan LIU Jin-biao AN Qin-qin WANG Zhi CHEN Shao-lin XU Bing-cheng | 2017 | Journal of Integrative Agriculture2017，16，6： | 3 |
| 5 | 小豆五出复叶pcl突变基因的精细定位和转录分析显示文摘为探究小豆复叶发育调控机理,本研究以电子束辐射小豆栽培品种京农6号获得的一个稳定遗传的五出复叶突变体pcl(pentafoliate compound leaf)为材料,进行了主要农艺性状调查、遗传分析、基因定位和转录组分析。结果表明,五出复叶小豆个体的株高、茎粗、单株荚数、荚宽、单荚粒数、单株产量和百粒重较三出复叶个体均显著增加。遗传分析结果表明,五出复叶由一对隐性基因控制。将突变基因定位于5号染色体末端上物理距离约为500 kb的区间内,区间内共注释出27个基因。染色体步行结果发现,VaTMK3基因启动子区域TATA-box中存在碱基突变,该突变位点分析与性状共分离。转录组和实时荧光定量PCR(qRT-PCR)分析结果显示,参与生长素信号转导和细胞扩增和增殖调控基因VaTMK3表达显著上调。同时生长素跨膜转运载体蛋白编码基因VaPIN1a、VaPIN1b、VaLAX1、VaLAX3、VaLAX5表达量均增加。由此初步确定五出复叶突变候选基因为VaTMK3,且VaTMK3影响了叶片中生长素的转运,从而影响了复叶发育。本研究为进一步解析小豆复叶发育调控分子机制提供了理论依据,为后续小豆复叶发育调控网路的建立奠定了研究基础。 | 刘震 邓勇 赵超绮 星君宜 万平 杨凯 | 2023 | 核农学报2023，37，6： | 0 |
| 6 | 小豆缺铁突变体分离群体叶色及产量性状分析显示文摘为了鉴定小豆铁吸收代谢突变体作图群体叶色性状的变异及其对产量的影响,本研究调查了‘河北801’(耐缺铁野生型)×FMY011(缺铁敏感突变体)和MY076(耐缺铁突变体)×GM352(缺铁敏感资源)的F_(2)分离群体的叶色分离情况,测定了叶绿素SPAD值,并分析了其与单株产量及其他农艺性状的相关性。F_(2)群体分离出新叶黄化和正常单株,其叶绿素SPAD值差异极显著。相关性分析显示SPAD值与单株产量、单株荚数、百粒重呈极显著正相关,缺铁引起的新叶黄化会降低小豆产量。缺铁胁迫验证田间叶色分离表型,结果显示‘河北801’×FMY011群体的叶色表型与田间叶色分离符合度高,新叶黄化F_(2)单株的F_(2:3)家系全部黄化,新叶绿色F_(2)单株胁迫下其96.62%F_(2:3)家系表现正常绿叶或呈杂合叶色分离,3.38%新叶绿色F_(2)单株胁迫下其F_(2:3)家系新叶黄化,表型不符合。MY076×GM352分离群体,田间正常叶色与缺铁胁迫鉴定的叶色一致,但田间新叶黄化F_(2)单株胁迫下仅有36.07%的F_(2:3)家系仍新叶黄化,60.66%新叶黄化F_(2)单株胁迫下其F_(2:3)家系表现为杂合叶色分离,3.28%新叶黄化F_(2)单株胁迫下其F_(2:3)家系叶色正常表型不符合。本研究为进一步定位克隆小豆中铁吸收代谢相关基因和铁生物强化育种提供了基础材料。 | 晁兴晨 顾忠珺 万平 杨凯 曹劲宏 赵波 李奕松 | 2024 | 分子植物育种2024，22，2： | 0 |
| 7 | Stability evaluation of the PROSPECT model for leaf chlorophyll content retrieval显示文摘The radiative transfer model,PROSPECT,has been widely applied for retrieving leaf biochemical traits.However,little work has been conducted to evaluate the stability of the PROSPECT model with consideration of multiple factors(i.e.,spectral resolution,signal-to-noise ratio,plant growth stages,and treatments).This study aims to investigate the stability of the PROSPECT model for retrieving leaf chlorophyll(Chl)content(Cab).Leaf hemispherical reflectance and transmittance of oilseed rape were acquired at different spectral resolutions,noise levels,growth stages,and nitrogen treatments.The Chl content was also measured destructively by using a microplate spectrophotometer.The performance of the PROSPECT model was compared with a commonly used random forest(RF)model.The results showed that the prediction accuracy of PROSPECT and RF models for Cab did not produce significant differences under varied spectral resolutions ranging from 1 to 20 nm.The ranges of the relative root mean square errors(rRMSE)of the PROSPECT and RF models were 12%-13%and 11.70%-12.86%,respectively.However,the performance of both models for leaf Chl retrieval was strongly influenced by the noise level with the rRMSE of 13-15.37%and 12.04%-15.80%for PROSPECT and RF,respectively.For different growth stages,the PROSPECT model had similar prediction accuracies(rRMSE=9.26%-12.41%)to the RF model(rRMSE=9.17%-12.70%).Furthermore,the superiority of the PROSPECT model(rRMSE=10.10%-12.82%)over the RF model(rRMSE=11.81%-15.47%)was prominently observed when tested with plants growth at different nitrogen treatment levels.The results demonstrated that the PROSPECT model has a more stable performance than the RF model for all datasets in this study. | Li Zhai Liang Wan Dawei Sun Alwaseela Abdalla Yueming Zhu Xiaoran Li Yong He Haiyan Cen | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 0 |
