This study aimed to investigate the effects of Lasiodiplodia theobromae (Pat.) Griff. & Maubl (L. theobromae) inoculation on the energy status and activity of adenosine triphosphatase (ATPase) during L. theobromae-induced disease development and pericarp browning of harvested ‘Fuyan’ longan (Dimocarpus longan Lour. cv. Fuyan) fruit. The results showed that, compared to the control longans, L. theobromae-inoculated longans displayed higher indices of fruit disease and pericarp browning, lower pericarp ATP and ADP contents, higher AMP content, lower level of energy charge, as well as lower activities of Ca²⁺-ATPase, Mg²⁺-ATPase and H⁺-ATPase in membranes of plasma, vacuole, and mitochondria. These results indicated that the infection of L. theobromae reduced energy status and ATPase activities, caused ions disorder, damaged the integrity and function of the cell and organelles including vacuole and mitochondria in pericarp of longan fruit, which contributed to L. theobromae-promoted disease development and pericarp browning of harvested longan fruit during storage.

这项研究旨在调查Lasiodiplodia theobromae（Pat。）Griff的影响。＆Maubl（L. theobromae ）接种收获的'Fuyan'龙眼（Dimocarpus longan Lour。cv。Fuyan）果实诱导的L. theobromae病害发展和果皮褐变期间的能量状态和腺苷三磷酸酶（ATPase）活性。结果表明，与对照相比，桂圆，L. theobromae -inoculated桂圆显示病果和果皮褐变的高指标，降低果皮ATP和ADP含量，更高的AMP含量，能荷水平较低，以及较低的活动Ca ²⁺ -ATPase，Mg ²⁺ -ATPase和H ⁺-ATP酶在质膜，液泡和线粒体的膜中 这些结果表明，感染的L. theobromae降低的能量状态和ATP酶活性，引起离子紊乱，损坏的完整性和细胞功能和细胞器，包括液泡和线粒体中龙眼水果果皮，这有助于L. theobromae促进的疾病贮藏过程中收获的龙眼果实发育和果皮褐变。
