Other claims from this paper (5)

Observation Leaf vein cells produced a tissue culture that was maintained through monthly transfers for two and one-half years.
Intervention effect Indole-3-acetic acid had no effect on leaf tissue growth.
Intervention effect Coconut milk greatly enhanced leaf tissue growth.
Intervention effect Heller’s medium plus coconut milk was best for leaf tissue growth.
Intervention effect Adding coconut milk to White’s medium decreased the percentage dry weight of the leaf tissue culture.

Title

The Effects of Phosphorus and Calcium Deficiency on the Growth and Dry Matter Production in Chrysanthemum coronarium var. spatiosum in Water Culture

Yasuhiko TEZUKA Shokubutsugaku Zasshi 1959. doi:10.15281/jplantres1887.72.101

Other claims from this paper (8)

Intervention effect Phosphorus deficiency increased chlorophyll content in leaves, causing dark greening.
Intervention effect Calcium deficiency caused necrosis of apical buds.
Intervention effect Calcium deficiency retarded the development of each leaf.
Intervention effect Phosphorus deficiency markedly reduced photosynthetic activity per unit leaf area.
Intervention effect Phosphorus deficiency decreased respiratory activity of each organ.
Intervention effect Calcium deficiency considerably decreased photosynthesis per unit dry weight.
Mechanism The decrease in growth caused by phosphorus deficiency is explained by dry matter production.
Observation Phosphate and calcium ion effects on plant growth depend on the whole amount available to the plant rather than on concentration.
