Other claims from this paper (6)

Intervention effect Nitrogen anaerobiosis after day 2 accelerated seedling dry weight loss during treatment.

The effect of reversion and duplication of leaf disks on the accuracy of photosynthesis determination by the dry weight method

Zdenêk Šesták; Jitka Vodová Biologia Plantarum 1965. doi:10.1007/bf02920626

Other claims from this paper (7)

Intervention effect Reversing sunflower leaf disks reduced photosynthetic rate by as much as 26% at full and half irradiation.
Intervention effect Reversing fodder cabbage leaf disks reduced photosynthetic rate by as much as 26% at full and half irradiation.
Intervention effect Stacking two disks reduced photosynthesis in the upper disk similarly to reversal.
Observation Lower stacked disks assimilated 0–40% as much as upper disks, reaching the compensation point in thick leaves.
Intervention effect Two disks exceeded one normal disk in total photosynthetic dry-weight gain only in thin leaves at high radiation.
Recommendation The authors advise discarding samples when a quarter of leaf disks were reversed.
Recommendation For samples with accidentally duplicated disks, the authors advise deducting one control disk weight.
