概括

将根区温度 (RZT) 提高3°C,改善了水培生菜的生长,营养吸收和关键代谢物,如叶绿素. 这一发现提高了工厂的生产力,并为优化在受控环境中的RZT提供了基础.

科学领域:

植物生理学植物生理学
控制环境农业农业
培技术是一种水培技术.

背景情况:

根区温度 (RZT) 显著影响植物生长和新陈代谢,但与空气温度相比,其具体影响需要进一步研究.
了解RZT的影响对于优化在植物工厂等受控环境中的植物生产至关重要.

研究的目的:

研究高RZT对红叶生长,基本元素和关键代谢物的影响.
为了确定是否增加空气温度以上3°C的RZT提高了植物的生产力和质量.

主要方法:

在一个植物工厂,在四个空气温度 (17,22,27,30°C) 下,用水培养方式种植红叶.
实施两种RZT治疗:一种是RZT高于空气温度3°C,另一个是没有RZT升高的对照组.
分析植物生长,叶绿素,胡卜素, Askorbic 酸,矿物元素,氨基酸和总溶性蛋白质.

主要成果:

较高的RZT (3°C高于空气温度) 在所有测试的空气温度中显著改善了植物生长,叶绿素,胡卜素和酸含量.
增加的RZT增强了基本元素 (Mg,K,Fe,Cu,Se,Rb) 的吸收,并提高了叶中的氨基酸和总可溶性蛋白质水平.
这些改善归因于营养吸收增加和激活根代谢.

结论:

相对于空气温度,将RZT提高3°C,同时提高了水培生菜中的植物生长和代谢物生产.
与空气温度相关的RZT优化是改善植物工厂作物产量和质量的有希望的策略.
进一步的研究应该探索各种RZT差异,日间效应和茎加热影响,以进行先进的优化.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

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.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
