Plant Breeding and Biotechnology

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.

食品科学食品科学食品科学

背景情况:

长期太空任务需要可持续的粮食生产解决方案.
虽然在太空中种植生菜已被理解,但在微重力环境下谷物作物的质量仍未得到充分探索.
了解小麦的质量对于未来的太空农业至关重要.

研究的目的:

研究微重力对小麦核重量,尺寸和不对称性的影响.
分析太空小麦的粉成分和细胞结构.
为了确定在太空中种植的小麦对质量的潜在影响.

主要方法:

在国际空间站 (ISS) 的Lada生长室里种植Triticum aestivum L. (超矮人品种).
比较100个太空成熟的核和85个在相同的陆地条件下生长的对照核.
分析核的重量,面积,长度,宽度,粉颗粒的特征,以及aleurone细胞尺寸.

主要成果:

与地球上种植的小麦核相比,国际空间站种植的小麦核在重量,面积,长度和宽度上显示出微小的差异.
微重力并没有增加核的不对称性;空间和地球样本都表现出低的不对称性.
在太空培养的小麦中,A型粉颗粒较长,而粉颗粒的宽度和圆度相似.
在太空成熟的核中,亚勒层细胞显著更窄.
由于不同的粉类型比率,假设空间种植的小麦的烤质量略低一些.

结论:

与陆地小麦相比,在太空中种植的小麦 (Triticum aestivum L.) 在内核参数和细胞结构方面表现出微妙但显著的差异.
微重力条件似乎不会对核对称性产生负面影响.
需要进一步的研究,以充分理解对质量的影响,并优化基于太空的谷物生产.
提出了一种新的,非破坏性的方法来评估内核不对称性.
