Scoring of senescence on wheat

This training program can be used to improve your ability to score wheat senescence. The photos were taken by Marie-Odile Bancal (UMR Environnement et Grandes Cultures, INRA Grignon).

The training program is available HERE

Rating scale:

As a user of the training program, you will be shown photos of wheat leaves. You will have to assign them to one of 11 severity classes, depending on the percentage of senescent leaf area (click on the photos to magnify them!):

Class

Description

Example

0

<5% of the leaf area is senescent
Wheat senescence example class 0

1

5-15% of the leaf area is senescent
Wheat senescence example class 1

2

15-25% of the leaf area is senescent
Wheat senescence example class 2

3

25-35% of the leaf area is senescent
Wheat senescence example class 3

4

35-45% of the leaf area is senescent
Wheat senescence example class 4

5

45-55% of the leaf area is senescent
Wheat senescence example class 5

6

55-65% of the leaf area is senescent
Wheat senescence example class 6

7

65-75% of the leaf area is senescent
Wheat senescence example class 7

8
