Abstract  Tree peony seed is unique for its super-high content of unsaturated fatty acid and is thus considered as an important
source of woody oil. However, photosynthetic production is greatly reduced under high light intensity and air temperature
during the seed filling period, which negatively affects seed yield and quality. The objective of this study was to determine
if appropriate shading improves yield and quality of seed in oilseed peony. In this study, oilseed peony trees were shaded
by different density polyethylene nets from four weeks after flowering to harvest stages to form light, moderate, and severe
shadings, equivalent to about 80, 40, and 20% of full solar exposure, respectively. The effects of different shadings on
some physiological parameters, yield and yield components, and nutritional composition of seed were examined. Averaged
across two years, light shading increased the actual net photosynthetic rate (Pn) by 16.8%, the maximum net photosynthetic
rate (Pmax) by 81.4%, chlorophyll (Chl) content by 52.8%, auxin (IAA) content by 38.1%, and gibberellic acid (GA3) content
in leaves by 6.3%; it decreased the accumulation of H2O2 in leaves by 24.8%, malondialdehyde (MDA) by 22%, and
endogenous abscisic acid (ABA) by 8.8%, indicating that leaf senescence in late season was considerably delayed. Light
shading increased seed yield, and contents of crude fat and unsaturated fatty acids by 9.7, 5.6, and 9.6%, respectively,
while moderate or severe shading significantly reduced all the three parameters. Light shading increased seed weight,
but moderate or severe shading reduced seed weight or follicle density. The improved seed yield under light shading was
mainly due to increased seed weight, while the reduced seed yield under moderate or severe shading was mainly attributed
to reduce follicle density and seed weight. The improved seed weight and content of unsaturated fatty acids under light
shading was possibly due to the delayed leaf senescence. The overall results indicated that light shading is beneficial to
yield and quality parameters of seed in oilseed peony. Cultivating oilseed peony under a light shading environments such as
partially closed forests would better increase total output and income per unit land area than that under full solar exposure.
