1886 S. H. Vines Lect. Physiol. Plants 502 The plagiotropism of dorsiventral organs, such as shoots and leaves,..is the resultant expression of the effect of light and of gravity upon them, promoted, in many cases, by their own weight.
1935 New Phytologist 34 108 In Avena coleoptiles and leaves and Zea mais radicles growth on the klinostat has different effects from that of Lupinus albus and Helianthus annuus seedlings, which may be correlated with the plagiotropism of the former seedlings.
1986 Forestry 59 161 Cuttings..taken from 6-years-old ortets..have poorer height growth and form with a high incidence of plagiotropism four years after planting.
