Claim · model-written summary

The seasonal leaf moisture decline was primarily due to dry weight rising faster than actual water content fell.

Claim · model-written summary

Differences in CO2 and radiation supply and tissue photosynthetic capacity were proposed to explain lower rates in reversed and doubled disks.

Outcome: decrease in photosynthetic ratee0
Qualifier: differences in the supply of CO2 and radiation energye0

“The decrease in photosynthetic rate found in reversed and duplicated disks is evidently due to the simultaneous effect of differences in the supply of CO2 and radiation energy to the assimilating tissue and apparatus and also to differences in the photosynthetic capacity of different leaf tissues”

Title

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.
