段落摘譯...與植物病害有關...謝謝大家!!

The disease-causing organisms are present in

and around the plant and attack living tissues under particular condition that weaken the host.

For example, the hyphae of botryosphaeria dothidea often are present in the bark of birch(betula alba)

and several often tree species and grow on dead stem or banch tissues saprophytically when the tree is

in a vigorous condition(106).

However, when the tree is subjected to a water deficit,cankers form in living stem tissues(36).

When the water deficit is relieved,the cankers stop developing and b. dothidea reverts to a saporophyte

in the killed tissue.

There is a similar development of cankers on white ash(fraxinus americana L.)

from attack by Cytophoma pruinosa and fusicoccum species,which are part of the normal microflora of

the tree but attack when the tree are subjected to drought(100,119).

    The disease-causing organisms are present in and around the plant and attack living tissues under particular condition that weaken the host.

    此致病有機組織出現在植物的裡面或四周,然後在特定情況下攻擊活著的組織,讓寄主虛弱

    For example, the hyphae of botryosphaeria dothidea often are present in the bark of birch(betula alba)and several often tree species and grow on dead stem or banch tissues saprophytically when the tree is in a vigorous condition(106).

    比如輪紋病菌絲常出現於白樺樹皮或其他幾種樹上,長在死莖上,或是在樹很強健的情況下在枝幹組織上寄生

    However, when the tree is subjected to a water deficit,cankers form in living stem tissues(36).

    要是樹缺水的話,在活的莖組織部分會有潰瘍病

    When the water deficit is relieved,the cankers stop developing and b. dothidea reverts to a saporophyte

    要是缺水狀況停止,潰瘍病也會跟著停止,木潰瘍病菌B. dothidea會轉換成寄生物長在死亡組織部份

    in the killed tissue.

    There is a similar development of cankers on white ash(fraxinus americana L.)from attack by Cytophoma pruinosa and fusicoccum species,which are part of the normal microflora of the tree but attack when the tree are subjected to drought(100,119).

    在美國白蠟樹身上也有大致相似的情況,在被Cytophoma pruinosa和殼梭孢屬攻擊,原本只是普通小型土壤植物,但是樹要是缺水就會發動攻擊
