俱舍論疏 18.153

18.153

論「如是施主至或果全無」，合法也。由可令果全無，非全顛倒，此舉大體。如江南為橘，江北為枳，亦由田也。此類少別，非全顛倒也。

Regarding the Śāstra's "Likewise, when a donor..." down to "...or has no result at all": this applies the analogy to the doctrine. Because it can cause the result to be completely nonexistent, not entirely inverted, this states the general principle. Just as [a tree] south of the Yangtze is a sweet orange, while north of the Yangtze it is a bitter orange, it also depends on the field. This type differs slightly, but is not entirely inverted.
