“…Besides these measures, as a simple cultivating measure involved in controlling the summer high temperature, shade has drawn much attention over the past several decades. Armson et al (2012) found that the surface temperatures of grass in shade can be 4-7°C cooler than the surrounding air, and our previous study also revealed shade reduced leaf temperature in P. lactiflora (Zhao et al, 2012a). Therefore, shade is widely applied in horticultural plants in summer.…”

High temperature stress has a significant impact on plant growth and development. Herbaceous peony (Paeonia lactiflora Pall.) is a very important landscape plant used in greenbelt whose growth is restrained seriously by high summer temperature, but little is known about relevant solving measures. In order to find an effective measure, this paper studied the effect of black shading net with about 60% transmittance on alleviating the thermal damage of P. lactiflora under field conditions. The results showed that P. lactiflora physiological indices were higher in shaded plants than those in sun-exposured plants especially in the late stages of higher temperature, such as chlorophyll (Chl) a, Chl b, Chl a+b, soluble sugar, soluble protein contents; whereas the exception to the trend was in Chl a/b and malondialdehyde (MDA) content. Moreover, compared with sun exposure, shade increased P. lactiflora protective enzymes activities, made mesophyll cell ultrastructures more intact, the chloroplasts more round and the grana lamellaes arrange relatively neatly, which led to enhance its photosynthesis rate (Pn) and transpiration rate (Tr). Additionally, the full-length cDNA of a heat shock protein gene (HSP70) containing 2195 bp nucleotides was obtained from P. lactiflora, and the expression analysis of PlHSP60, PlHSP70 and PlHSP90 in four developmental stages showed that shade caused PlHSP60 and PlHSP70 expression levels to rise especially in the late stages. These results indicated that shade alleviated the thermal damage of high temperature stress to P. lactiflora through scavenging reactive oxygen species, protecting cell structures, enhancing photosynthesis and the expression levels of HSP under high temperature stress, which might lay a theoretical foundation for P. lactiflora safe over summering and cultivated form in summer.

“…Moreover, the effects of shade on P. lactiflora plant growth under optimum temperature had been clarified by us (Zhao et al, 2012a). Nevertheless, the effect of shade-induced thermotolerance was still far from being complete.…”

“…Relative to plants grown under high light intensity, plants grown under low light intensity have thinner leaves and higher chlorophyll content and have lower amounts of ribulose-1,5-bisphosphate carboxylase/ oxygenase (Rubisco), electron-transport carrier, and carbon assimilation enzymes per unit of leaf area (Anderson, 1986;Baldi et al, 2012;Seemann et al, 1987;Zhao et al, 2012). As a consequence, the carbon assimilation rate and the capacity for dissipation of excessive excitation energy are lower in plants grown under low light (Jiang et al, 2011;Li and Cheng, 2008;Chen et al, 2012).…”

“…Light change not only affects plant morphology, physiology and microstructure but also has an important impact on crop production. This is mainly because plant growth requires an appropriate light intensity; excessively high or low intensity will prevent photosynthesis in the plant (Zhao et al, 2012). Leaves on plants grown under shade show higher leaf area and allocate more of their resources to shoot production, and also have greater specific leaf area.…”

Field experiments were conducted in 2013 and 2014 with eight treatments consisting of combination of four shading periods (shading during vegetative phase (V), reproductive phase (R), whole growing season and a control treatment) and two irrigation regimes (irrigation after depleting 40 and 80 % of available water). Under limited irrigation conditions, the highest PSII quantum yield, the capacity of electrons move beyond QA and electron move from intersystem to PSI acceptor side reduced, with greater decline degree in sunlight treatment. The minimum seed yield was recorded by plants treated with limited irrigation and whole growing season shade. Changes in the state of the photosynthetic electron transport chain and photorespiration rates in response to different shading treatments were primarily related to leaf water loss. In general, the results revealed that shading caused some shade avoidance responses in soybean, which finally reduced seed production.
