不同浓度PEG模拟干旱胁迫对燕麦种子胚根和胚芽生长的影响

本研究采用PEG-6000溶液模拟干旱胁迫条件,比较研究了冀北地区12个燕麦品种(品系)种子胚根和胚芽的生长变化及萌芽期抗旱性表现。结果表明,不同燕麦品种种子初生根数、初生根长、胚芽长和胚芽鞘长对干旱胁迫的响应不同。不同干旱胁迫条件下,燕麦种子初生根数在0～5之间,其中低度干旱胁迫增加了燕麦种子初生根数,高度干旱胁迫降低燕麦种子初生根数。不同燕麦品种种子最长初生根长在5～20.9 mm之间,干旱胁迫均降低了燕麦种子最长初生根长,其中200919-7-1、坝莜3号和品五对干旱胁迫的忍耐性最高。干旱胁迫也影响了燕麦种子胚芽长和胚芽鞘长,不同燕麦品种种子胚芽长和胚芽鞘长对干旱胁迫的响应表现出相似的趋势。     

梨树的丰产栽培技术

正西华县是河南省的重点林业生态县,全县有林地面积17万hm~2,森林覆盖率23.6%。自20世纪90年代开始栽培梨树,至2015年有梨园面积1300hm~2,梨产量12269t。梨产业已成为西华县农民致富的阳光产业。笔者从梨树的建园、土肥水管理、花果管理、整形修剪、病虫害防治等方面介绍了梨树的丰产栽培技术,为梨树生产提供参考。1果园建立1.1园地选择选择交通方便、向阳、离柏树较远的地方建园。     

Evaluation of adaptability of naked oat varieties in the alpine region of North China based on the AMMI model and GGE Biplot北大核心CSCD

In order to comprehensively evaluate the productivity, stability and adaptability of varieties of naked oats, as well as the discriminative power and representativeness of testing sites in the alpine region of North China, data for six naked oat varieties and six testing sites in 2019 were analyzed and evaluated using the AMMI （additive main effects and multiplicative interaction） model and GGE （genotype main effect plus genotype-environment interaction） biplot. It was found that analyses of naked oats regional trial results using the two methods together reduced the statistical error and increased the ability to declare variety means significantly different, compared to traditional ANOVA methods. It was found that genotype, environment, and genotype×environment interaction effects all contributed to differences in grain yield. Variety 200910-28-4-3（G2） showed the best performance in both grain yield and stability of yield across sites, followed by varieties 200910-5-2（G3） and 200910-22-1（G4）. In terms of the selection of regional adaptability test sites for varieties, Ulanqab pilot in Inner Mongolia had both good representativeness and strong discriminability, and was the most ideal test site. Chongli Shizigou Seed Farm and Zhangbei Base were also comparatively good test sites. This study provided a scientific evaluation of methodology for performance testing of naked oat varieties in the alpine region of north China and the results basis will assist future breeding and promotion. © 2022 Editorial Office of Acta Prataculturae Sinica.
