物理抗性

在此计算中，负的目标物理抗性被当作0%避免它增加粉碎性打击的效果。

In this calculation , a negative physical resistance is treated as0 % to prevent it from increasing the effect of the crushing blow .

然而，有一条减少粉碎性打击效果的特殊规定，就是是否会被物理抗性所影响。

However , there is a special coding , which reduces the effect of a crushing blow as if it was affected by the physical resistance of the target .

非寄主抗性涉及植物叶面或表皮细胞提供的预成型物理或化学壁垒，这些预成型保护机制不仅可以阻止侵染结构的建立，而且能够诱导物理或化学抗性（Heath2000；MysoreandRyu2004）。

NHR can involve preformed physical or chemical barriers present on the plant surface or in epidermal cells that can stop establishment of infection structures as well as induced physical or chemical defenses ( Heath 2000 ; Mysore and Ryu 2004 ) .
