Leaf Area Index Estimated by the Digital Photography Method (LAIM) (LAID), specific leaf area (SLA), light intercepted by the canopy (Ic), measured extinction Comparison between leaf area index estimated by cover digital images considering In this study, measurements of canopy light interception and digital cover images were taken four 	./cache/work_nfw762pwkrhk3a3mfhrpxoal4q.pdf	./txt/work_nfw762pwkrhk3a3mfhrpxoal4q.txt
