概括

和在Xanthoceras sorbifolium中显著影响雌性花的形成,而促进雄性花的形成. 应用更高度的气可以改善雌雄花的比例,并推迟开花时间.

科学领域:

植物生理学植物生理学
农业科学农业科学
植物学植物学

背景情况:

桑托塞拉斯 (Xanthoceras sorbifolium) 是中国的一种重要的木质油植物.
作为一种单一的物种,优化雌雄花的比例是提高产量的关键.
在X. sorbifolium中,花呈现出明显的位置分布:雌性在上部,雄性在中间,以及枯在下部的发芽部分.

研究的目的:

调查营养元素对X. sorbifolium的芽分化和花朵形成的影响.
为了确定 (N), (P) 和 (K) 在花的性别确定中的特定作用.
评估不同叶片度对雌雄花比例和开花现象学的影响.

主要方法:

从植物的上部,中部和下部收集了叶子,芽和的样本.
在芽分化过程中分析了 (N), (P), (K),可溶糖和粉的含量.
在性别分化之前,对不同的叶子N度 (0.5%和0.8%) 进行了受控的应用.

主要成果:

发现 (N) 和 (P) 显著促进了雌性花的形成,而 (K) 则有利于雄性花的发展.
女性花的发育似乎与更高的可溶糖含量有关,而男性花的发育需要更多的粉.
叶子中高度的N (0.5%和0.8%) 显著增加了雌花的数量,并改善了雌花与雄花的比率,并将开花时间提前4天.

结论:

营养因素,特别是N和P,在调节X. sorbifolium的花性别决定和芽分化方面发挥着至关重要的作用.
优化N和P水平可以是一个可行的策略,以提高雌性花的生产和提高产量.
这些发现为操纵X. sorbifolium种植中的雌雄花比例提供了营养基础.

Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Introduction to Seed Plants

Introduction to Seed Plants

Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms.

The Tongue and Taste Buds

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

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.
