Excess irradiance causes early symptoms of senescence during leaf expansion in photoautotrophically in vitro grown tobacco plants
accelerated leaf development and caused early symptoms of leaf senescence. The symptoms were: decreasing chlorophyll a+b content and chlorophyll a/b ratio, decreasing both-photochemical quenching of chlorophyl...

SPAD chlorophyll meter reading can be pronouncedly affected by chloroplast movement
Non-destructive assessment of chlorophyll content has recently been widely done by chlorophyll meters based on measurement of leaf transmittance. However, the leaf transmittance depends not only on the content of <...

Factors of between- and within-plant distribution of Metopolophium dirhodum (Hom., Aphididae) on small grain cereals.
The relationship between abundance and leaf chlorophyll content of spring wheat, spring oats and winter barley was investigated. Aphid numbers on leaves of particular order (within-plant distribution) were correlated with leaf

The inexpensive tool for the determination of projected leaf area
Leaf area is useful basis for the expression of the photosynthetic activity, specific leaf area, content of chlorophylls and carotenoids, etc. However, commercial devices are quite expensive. Therefore, we propose a low cos...
