Leaf epidermal characters related with plant's passive resistance to pathogens vary among accessions of wild beans Phaseolus vulgaris var. aborigineus (Leguminosae–Phaseoleae)

Nitrogênio e as características anatômicas, bromatológicas e agronômicas de cultivares de Brachiaria brizantha

“…A transpiração torna-se um processo mais eficiente em gramíneas, que são plantas anfiestomáticas, ou seja, apresentam estômatos em ambas as superfícies das folhas (Steinglein et al, 2005).…”

Evaluation of susceptibility of an olive progeny (Picholine x Meski) to olive leaf spot disease caused by Fusicladium oleagineum

“…It is generally believed that pubescent leaves will be more resistant against pathogens, pests and drought than less pubescent ones of the same species due to a mechanical restriction to pathogen activities caused by a high density of trichomes (Levin 1973). Trichomes are important structural barriers and components of resistance and are also sites for accumulation of secondary metabolites that may act as defensive, repellent or toxic compounds (Stenglein et al 2005).…”

Leaf (or assimilation branch) epidermal micromorphology of desert plant in arid and semiarid areas of China

“…界环境进行气体交换, 又能保持水分。随着环境中 水分和湿度的减少, 气孔密度增加, 气孔面积则向 小型化发展, 气孔多下陷形成气孔窝或其上有突出 的角质膜 (Sam et al, 2000;Bosabalidis & Kofidis, 2002;高建平等, 2003;Xu & Zhou, 2008;Gan et al, 2010;de Micco & Aronne, 2012)。叶表皮附属物(如 表皮毛和表面疣状突起物)也发生变化, 它们可有 效地避免叶肉组织受损 (Gairola et al, 2009;Koch et al, 2009;Gomes et al, 2011;Noman et al, 2012), 表 皮蜡质(waxes)晶体形成二维或三维结构, 具有降低 表皮的可湿性以及反射强光等作用 (Wagner et al, 2003;Koch & Ensikat, 2008)。 植物叶表皮微形态特征已用于解决物种分类问 题、建立物种进化关系、阐明表皮微形态结构的生 态适应性等多种研究目的 (Dickison, 2000;Scatena et al, 2005;Stenglein et al, 2005;Aliero et al, 2006;Chen et al, 2010;Zhou & Xia, 2012;Adebowale et al, 2014;Deng et al, 2014;Zhang et al, 2014;Francisco et al, 2015;朱广龙等, 2016 www.plant-ecology.com …”
