Claim · model-written summary
The seasonal leaf moisture decline was primarily due to dry weight rising faster than actual water content fell.

e0“The seasonal decrease was traceable primarily to greater increase in leaf dry weight than to decrease in actual water content”

Other claims from this paper (9)
- Observation Bud moisture content increased until bud opening in angiosperms and gymnosperms.
- Mechanism Rapid moisture translocation into buds primarily accounted for the moisture content increase.
- Observation Angiosperm leaf moisture content decreased rapidly early in the season and slowly after midsummer.
- Observation Actual water in expanding leaves increased while percent dry weight moisture decreased early in the season.
- Observation Leaf dry weight increased faster than water uptake during the same period.
- Observation Foliage water amount changed little after mid June in most angiosperms.
- Observation Current year needle moisture declined progressively.
- Observation One year old needle moisture first increased and then leveled off.
- Mechanism Needle age differences largely reflected dry weight changes from carbohydrate translocation.
