To this purpose, the six kinds of cereals in stage of heading were examined on “index of greenest”: oat, barley Rataj and Nagrad, triticale, wheat and rye. Statistical analysis carried out afterwards demonstrated that, between measurements received from two chlorophyll meter founded high efficiency of linear regression. To recount values between the chlorophyll meters can be use equation: (N-tester reading) = 14.5·(SPAD reading) – 73.4.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskachlorofilchlorofilometrregresja liniowazbożechlorophyllchlorophyll metercornlinear regressionDyscyplina::Nauki rolniczeArticle2300-5378
