Other claims from this paper (9)

Association Plant and unit tiller weight increased throughout the season in the herbage removed at each cut.
Association The number of tillers declined, especially before shooting began.
Intervention effect Cutting up to 5 May did not affect the date of ear emergence.
Intervention effect Plants cut on 19 May had a slightly delayed date of ear emergence.
Intervention effect Plants treated subsequently flowered much later.
Observation The interval following defoliation before flowering was fairly constant.
Intervention effect Cutting on and after 7 April depressed fertile tiller formation with increasing severity.
Observation Only vegetative tillers appeared in the recovery growth after treatment at the beginning of August.

Isamu BABA; Yasuo TAKAHASHI; Iwaho IWATA Japanese Journal of Crop Science 1953. doi:10.1626/jcs.21.237

Other claims from this paper (8)

Intervention effect High night temperature after heading speeded up ripening of rice plants.
Intervention effect High night temperature after heading retarded normal grain development in rice.
Intervention effect High night temperature after heading diminished potassium and silica contents in rice stems and leaves.
Intervention effect High night temperature after heading increased rice susceptibility to Helminthosporium leaf spot.
Intervention effect Both high and low night temperature reduced absorption of K2O, SiO2 and NH3-N by rice.
Intervention effect Both high and low night temperature reduced absorption of MnO and P2O5 by rice.
Mechanism Supra-optimal and low night temperature are suggested to retard root aerobic metabolism and thereby reduce ion absorption in rice.
Mechanism Serious Helminthosporium leaf spot (Akiochi) occurrence in south-western Japan may be partly due to high-night-temperature inhibition of potassium and silica absorption.

Effects of 2,4-Dichlorophenoxyacetic Acid Upon the Nitrogen Metabolism and Water Relations of Soybean Plants Grown at Different Nitrogen Levels

S. R. Freiberg; H. E. Clark Botanical Gazette 1952. doi:10.1086/335724

Other claims from this paper (11)

Observation Nitrogen form redistribution after treatment was similar at high and low nitrogen.
Intervention effect 2,4-D caused sequential stem and petiole deformation, leaf yellowing and swelling, then wilting and drying.
Observation Visible responses to 2,4-D appeared sooner in high nitrogen plants.
Intervention effect 2,4-D-treated plants at both nitrogen levels did not appreciably gain dry weight, while controls accumulated dry matter.
Intervention effect Treated leaves had significantly less dry matter than controls after 23 hours.
Observation Treated leaves subsequently wilted and had a much higher dry matter percentage.
Intervention effect 2,4-D-treated plants failed to increase total nitrogen including nitrate, suggesting altered root absorption.
Intervention effect 2,4-D caused a decrease in protein nitrogen in leaves versus controls.
Intervention effect 2,4-D increased soluble organic nitrogen fractions in all organs relative to controls.
Mechanism The authors inferred leaf protein hydrolysis and translocation to stems and roots for protein resynthesis.
Mechanism 2,4-D may act differently on proteolytic enzymes among leaves, stems and roots.
