世界顶级遥感和野外表型专家,Hiphen首席科学家Fred Baret最近在Frontiers in Plant Science上发表了题为A High-Throughput Model-Assisted Method for Phenotyping Maize Green Leaf Area Index Dynamics Using Unmanned Aerial Vehicle Imagery的文章。

绿叶面积指数 (GLAI)动力学在诸多领域都有应用包括产量预测以及植物育种领域。研究人员介绍了一种利用无人机多光谱影像学模型辅助方法高通量鉴别玉米  (Zea mays subsp. mays)动力学的方法。在2016年和2017年,在水灌溉充足和灌溉不足处理的400行玉米植株上做了2次实验。每次UAV飞行,首先获取GLAI估值,估值来自经典多光谱反射以及地面微田块样本GLAI测量。之后计算样品生理学正确 GLAI 动力/GLAI比值模型 。结果显示, GLAI 动力学可通过循环 (R2 > 0.9)正确估算。模型的2个参数,最大叶面积以及叶寿命也被正确估算。研究表明,GLAI 动力学以及适应模型参数对环境条件的反映有可继承性(0.65 ≤ H2 ≤ 0.98),将产量与干旱耐受性连接到一起。该方法与植物生长模型、UAV影响以及无损田间测量结合在一起, 提供了新型高通量研究GLAI动力学适应性以及与环境互作的方法。GLAI 动力学是极有前景的植物育种方法,为未来遗传研究铺平了道路。

A High-Throughput Model-Assisted Method for Phenotyping Maize Green Leaf Area Index Dynamics Using Unmanned Aerial Vehicle Imagery

The dynamics of the Green Leaf Area Index (GLAI) is of great interest for numerous applications such as yield prediction and plant breeding. We present a high-throughput model-assisted method for characterizing GLAI dynamics in maize (Zea mays subsp. mays) using multispectral imagery acquired from an Unmanned Aerial Vehicle (UAV). Two trials were conducted with a high diversity panel of 400 lines under well-watered and water-deficient treatments in 2016 and 2017. For each UAV flight, we first derived GLAI estimates from empirical relationships between the multispectral reflectance and ground level measurements of GLAI achieved over a small sample of microplots. We then fitted a simple but physiologically sound GLAI dynamics model over the GLAI values estimated previously. Results show that GLAI dynamics was estimated accurately throughout the cycle (R2 > 0.9). Two parameters of the model, biggest leaf area and leaf longevity, were also estimated successfully. We showed that GLAI dynamics and the parameters of the fitted model are highly heritable (0.65 ≤ H2 ≤ 0.98), responsive to environmental conditions, and linked to yield and drought tolerance. This method, combining growth modeling, UAV imagery and simple non-destructive field measurements, provides new high-throughput tools for understanding the adaptation of GLAI dynamics and its interaction with the environment. GLAI dynamics is also a promising trait for crop breeding, and paves the way for future genetic studies.
