概括

小麦尖子流产,特别是在基底尖子中,是由花流产引起的,而不是同化可用性. 基底花的发育年龄降低与堕胎率的增加有关.

科学领域:

农业科学农业科学
植物生物学植物生物学
植物生理学作物生理学

背景情况:

小麦尖子显示出每个尖子的谷粒数量有显著的变化.
基底尖苗的发育时间较晚,往往会中止,导致谷物产量减少.

研究的目的:

调查小麦 (Triticum aestivum L.) 基底刺流产的原因.
确定花流产,同化可用性和发育年龄之间的关系.

主要方法:

使用阴影处理的实地实验.
在小麦中对花流产和发育年龄的分析.

主要成果:

基底尖端子流产与花流产有很强的相关性.
在整个高峰期内,同化剂的可用性没有差异.
基底花的发育年龄降低,前解剖是它们堕胎的关键因素.

结论:

在小麦中,基底尖端子流产主要是由于小麦发育年龄减少而导致的花流产.
未来的育种策略应侧重于增强基底尖的建立和花的发展速度.

Seed Structure and Early Development of the Sporophyte

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.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

The Angiosperm Life Cycle

The Angiosperm Life Cycle

Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.
