D. J. WATSON; GILLIAN N. THORNE; S. A. W. FRENCH Annals of Botany 1958. doi:10.1093/oxfordjournals.aob.a083616

Other claims from this paper (19)

Association Proctor and Herta yielded 10—15 per cent more grain than Plumage-Archer without nitrogen fertilizer.
Intervention effect Nitrogen increased the varietal grain yield difference to about 30 per cent.

Observation The three varieties had similar leaf-area index, net assimilation rate and total dry weight before ear emergence.
Association After ear emergence Herta had a smaller leaf-area index than Proctor and Plumage-Archer.
Observation Shaded-ear pot experiment found nearly equal dry matter contribution per leaf area across varieties.
Mechanism The authors attributed higher yield to photosynthesis by the ears.
Association In pots, Proctor and Herta yielded only about 6 per cent more than Plumage-Archer.
Association Field ear sizes were greater for Proctor and Herta than Plumage-Archer.
Association Ear dry weight at emergence was greater in the higher yielding varieties.
Observation Herta ears may have higher photosynthetic efficiency.
Association Plumage-Archer absorbed more potassium.
Association Herta absorbed less phosphorus than the other varieties.
Observation About a quarter of final nitrogen was absorbed after ear emergence.
Observation A third of phosphorus was absorbed after ear emergence.
Observation Potassium content was nearly maximal at ear emergence and later decreased.
Observation Ear photosynthesis contributed 26 per cent of grain dry matter, including 10 per cent from awns.

Intervention effect Sunflower total biomass did not change significantly under contamination.
Association Water deficit affected sunflower growth.
Intervention effect Hydrocarbon stress significantly increased sunflower reducing carbohydrates.
