科学领域:
- 农业学是一种农业学.
- 植物育种 植物育种
- 农业科学 农业科学
背景情况:
- 狭叶狼 (NLL, *Lupinus angustifolius* L.) 是料和食品的重要作物,需要高质量的种子来源.
- 在NLL中种子质量主要取决于类化合物,蛋白质,油和水分含量,影响其适合不同用途和储存.
- 了解这些种子特征和环境因素之间的相互关系对于开发改进的NLL品种至关重要.
研究的目的:
- 为了研究狭叶狼种子中蛋白质,油,类和水分含量的相关性.
- 评估环境条件,特别是天气模式对这些关键种子质量参数的影响.
- 确定在俄罗斯西北地区的NLL加入,具有最佳的生化特征,用于繁殖目的.
主要方法:
- 在俄罗斯西北部普什金镇,在三个生长季节 (2019年,2020年,2022年) 中,从VIR收藏中评估了62个NLL加入.
- 种子蛋白质,油,化物 (每毫克/100克干物质) 和水分含量的定量.
- 统计分析以确定生化参数之间的相关性,并评估天气变量 (温度,降水) 的影响.
主要成果:
- 观察到的变化:蛋白质 (27.8-37.6%),油 (3.9-7.3%),类化合物 (1.6-2017.4 mg/100 g DM),水分 (6.4-7.3%). 它们的含量是什么?

Overview
Dihybrid Crosses
Overview
Seed Structure and Early Development of the Sporophyte
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.
Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
Trihybrid Crosses
Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
