Studies of the Rate of Growth of Leaves by a Photographic Method I. The Determinants of the Rate of Growth of First Leaves of Phaseolusvulgaris

Compensatory Growth in Coleus Shoots

“…These experiments also differ in that the apical bud in these tobacco plants is not removed until it has differentiated into an inflorescence. Vyvyan (1924) cut off the apical and axillary buds of bean seedlings which had just unfolded the first pair of foliage leaves. On half the plants he also cut off one of the first foliage leaves.…”

Short‐term Fluctuations in Leaf and Inter‐node Growth in the Apple Rootstogk Crab C

“…Vyvyan (1924) obtained such a 'normal curve' by smoothing out the effect of environmental changes by observing comparable leaves on bean plants started at intervals of a few days. Gregory (1926) correlated several meteorological records with deviations from a normal growth curve of the barley plant, which he constructed by standardizing all his experimental curves by taking the period of the whole cycle as 100, and the maximum leaf area or dry weight attained as 100, and calculating all his data as percentages of these two values; through the resulting points smooth curves were drawn and values read off and averaged at given percentage time intervals.…”
