摘要

为监测3个日本品种和5个欧洲品种的马铃薯生长，建立了表型系统。根据无人机每周拍摄的影像，利用DSM和反射率图估算植物高度、体积和植被指数。无人机估计值与人工测量株高呈高度相关，决定系数R2为0.70。无人机估算的NDVI与人工测量的NDVI高度相关(相关系数R = 0.97)。欧洲品种如Euroviva的产量高于日本品种如Irish cobbler和Toyoshiro。体积和LCI与产量高度相关(R2分别为0.99和0.96)，是预测产量的理想参数。

Phenotyping system for precise monitoring of potato crops during growth

A phenotyping system was developed for monitoring the growth of 3 Japanese and 5 European varieties of potatoes. From the UAV images taken weekly, plant height, volume and vegetation indices were estimated from the DSM and the reflectance maps. UAV-estimated volume and manually measured plant height had a high correlation with a coefficient of determination R2 of 0.70. UAV estimated NDVI was highly correlated with the manually measured NDVI (correlation coefficient of R = 0.97). European varieties such as Euroviva had a higher volume compared to the Japanese varieties such as Irish cobbler and Toyoshiro. Volume and LCI were found to be highly correlated with the yield ( R2 of 0.99 and 0.96) thus ideal parameters for yield prediction.
