据《Scientia Horticulturae》的一篇研究报道(http://dx.doi.org/10.1016/j.scienta.2014.08.019),来自南非斯泰伦布什大学的Simeon Hengari等人研究了苹果果实不同发育期果皮光合系统对中度光合有效辐射下热胁迫的响应。供试条件下的光合有效辐射为500μmol/m·s,研究人员研究了30、35、40、45和50℃热胁迫对花后50、95和150天澳洲青苹、富士和Cripps’Pink苹果果皮光合系统的伤害。光损伤程度通过检测每个果实发育期光系统Ⅱ According to a study by Scientia Horticulturae (http://dx.doi.org/10.1016/j.scienta.2014.08.019), Simeon Hengari et al from the University of Stellenbosch in South Africa studied the different development of apple fruit Response of Pericarp Photosynthetic System to Heat Stress under Moderate Photosynthetically Active Radiation. Under the conditions of photosynthetically active radiation 500μmol / m · s, the researchers studied the heat stress of 30,35,40,45 and 50 ℃ after anthesis 50,95 and 150 days after anthesis Aussie, Fuji and Cripps'Pink apple Peel photosynthetic system damage. The degree of light damage is determined by measuring the photosystem II of each fruit developmental stage
