概括

白光比红光和蓝光更能提高矮番茄果生物质辐射利用效率 (FBRUE). 通过提高辐射利用效率 (RUE) 来实现这一目标,并观察到特定品种的好处.

科学领域:

植物生理学植物生理学
园艺科学园艺科学
农业工程农业工程

背景情况:

红光和蓝光比对矮番茄果生物质辐射利用效率 (FBRUE) 的影响尚不清楚.
在LED照明下的矮番茄中,白光相对于混合红色和蓝色光在提高辐射利用效率 (RUE) 和FBRUE方面的比较优势尚不清楚.

研究的目的:

为了研究不同红色和蓝色光比以及白色光对两种矮番茄品种的RUE和FBRUE的影响.
为了确定白光是否比混合红光和蓝光提供更优异的性能,以增强矮番茄中的FBRUE.

主要方法:

在受控条件下种植了两种矮番茄品种 ("Micro-Tom"和"Rejina").
应用了四种光处理:单色红光,红/蓝光比分为9:1和3:1,以及白光,均为300μmol m-2s-1.
测量包括特定的叶面积,反射率,透射率,吸收率,光合作用率,RUE,F_果和FBRUE.

主要成果:

由于叶子吸收率和光合作用率降低,单色红光产生了最低的RUE和FBRUE.
增加红蓝混合物中蓝光比例 (高达25%) 提高了光合作用率,导致RUE和FBRUE的增加.
与红光和蓝光治疗相比,白光显著增加了RUE (0.09-0.38 g mol-1) 和FBRUE (0.14-0.25 g mol-1).与红光和蓝光治疗相比,白光显著增加了RUE (0.09-0.38 g mol-1) 和FBRUE (0.14-0.25 g mol-1).
白光改善了"Rejina"中的水果分区 (F_水果) 和"Micro-Tom"中的水果Brix,证明了特定于品种的效果.

结论:

红色和蓝色光比影响FBRUE主要是通过影响RUE,而不是果实干质分区.
白光显示出比混合红色和蓝色光更大的潜力,可以在繁殖阶段改善矮番茄FBRUE.
特定种类对白光的反应表明,定制的照明策略可能有利于优化番茄产量.

Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

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.

Light as Energy

Light as Energy

The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

The Antenna Complex

The Antenna Complex

Plants and other photosynthetic organisms comprise pigments capable of absorption of direct sunlight. These pigments are present in the reaction center - the main site of photochemical reactions as well as in the antenna complex. Under average light conditions, the rate at which reaction center pigments absorb light is far below the electron transport chain's capacity. As a result, the reaction center alone cannot provide enough energy to drive photosynthesis. The photosynthetic efficiency...
