adversely 怎么理解在这句话中?

According to many gardening authorities, tomatoes should not be planted near dill because doing so is likely to affect their taste adversely

整句话我的理解是: 土豆不能种在莳萝旁边,会影响味道. Adversely 逆的,相反的. 在这里怎么翻译?是说莳萝令土豆变味,自己不变味,,还是反之, 再或者是两者相互影响,都变味儿

如果去掉,会影响句子的理解吗?

you are such a careful reader!

我的理解是，TOMATOES自己的味道会受影响

我知道了.their taste说明指的是tomatoes(复数) 而不是dill(单数),所以应该是tomatoes自己的味道受影响,而且是不利的影响(adversely).
