英文翻譯中文~請有興趣和好心人幫忙

因為自己不是很會英文~翻的都怪怪的!!拜託好心人士幫忙~

Water stress during critical stages of fruit ontogeny has also been shown to predispose fruit to defects

In internal fruit quality. Bower et al.156 related different irrigation schedules to the activity of the browning

Enzyme polyphenol oxidase in the mesocarp of mature fruit after harvest. When ¥s measured at 300

Mm was allowed to fall to-80 kpa before re-wetting.69 there was increased activity of polyphenol

Oxidase in these fruit compated to those grown where the ¥s did not exceed-55kpa. Fruit from the

Latter treatment had higher calcium levels in the mesocarp during the first 16 weeks of growth, which

Is known to improve membrane structure and reduce physiological fruit disorders.165-168 ring neck, a

Disorder of avocados in which corky lesions develop at the abscission sites on the fruit stalk<figure

13>, was first described in California,169 but is found in all countries where avocados are grown. The

Lesion usually develops at the junction of the pedicel and peduncle, but may also occur where the

Pedicel attaches to the fruit or where the peduncle joins the shoot.147 internal examination of the fruit

Shows that in all cases the testa encasing the seed has prematurely died. Haas170 and toerien171 suggested

That ring neck is due to either toxic or deficient nutrient levels in the pedicels. However, engelbrecht172

Proposed that ring neck is due to water stress during fruit development. This latter view is shared by

Whiley et al.,147 who found a direct correlation of the incidence of ring neck to water deficit in the tree.

Furthermore, it has been observed that the development of this symptom accelerates on mature ,,hass,,

Fruit held on the tree until the following spring. This period coincides with a reduction in root activity

<figure 10 > and increased water loss from the tree during anthesis.23

    果實成長重要階段的水壓力顯示,對有內部缺陷的果實會提前放棄。

    Bower等人比較了不同灌溉時刻的成熟果實於收穫後,其中果皮中,褐色酵素酵素多酚氧化酵素(browning Enzyme polyphenol oxidase )的活動。

    在300Mm的¥s在再潮濕前被允許下降至-80kpa時,和¥s沒有超過-55kpa的果實相較,氧化酵素多酚的活動會增加(activity of polyphenol Oxidase )。

    後者處理的果實,在前十六星期的成長內,中果皮中會有較高的含鈣量。我們知道,這是為了要促進細胞膜組織以及減少果實外觀的失調。

    圖13顯示,環頸(ring neck),一種酪梨的失調症,在果實莖部切除的部分會有軟木狀的紅斑(lesions )(如圖13所示)。這個症狀首先在加州被發現,其後,在種植酪梨的果園都可見其蹤跡。

    紅班常在花梗與花梗(pedicel and peduncle)的連接處產生,但也常在和果實或芽的連接處產生。

    果實的內部檢查顯示,外堅皮(testa )被嵌入(encasing )種子的話,必定會提前死亡。

    Haas和Toerien認為,環頸(ring neck )只有兩個起因,一是中毒、二是花梗的營養不足。

    然而, Engelbrecht覺得,環頸是因為水果發展期間的水壓所造成。

    Whiley等人也肯定後者的見解,他們發現環頸和水分不足之間有正相關。

    而且,研究顯示,環頸會在成熟的、還吊在樹上的hass果實上加速惡化,直到下個春天。

    圖10顯示這個階段和根部活動與開花期水分急遽的減少有一致性。

    水重音在果子個體發生學期間重要階段並且被顯示預先處理果子對瑕疵在內部水果質量。涼亭和al.156 與變褐的酵素多酚oxidase 的活動關係了不同的灌溉日程表在成熟果子中果皮在收穫以後。當¥s 被測量在300 毫米被允許下落對80 kpa 在re wetting.69 那裡是多酚Oxidase 的增加的活動在這些之前果子compated 對那些被種植¥s 沒有超出55kpa 的地方。果子從後者治療有更高的鈣水平在中果皮在第一16 個星期成長期間, 為人所知改進膜結構和減少生理果子disorders.165-168 圓環脖子, 裡軟木塞的損害顯現出在頓斷法站點在果子莖鮞梨的混亂在, 被描述了在加利福尼亞, 169 但第一次被發現在鮞梨被種植的所有國家。損害通常顯現出在pedicel 和peduncle 的連接點, 但也許並且發生Pedicel 附上對果子或的地方peduncle 加入果子的地方shoot.147 內部考試表示, 在所有案件testa 裝箱種子過早地死了。Haas170 和toerien171 建議了.提議, 圓環脖子歸結於水重音在果子發展期間。這種後者見解由Whiley 等, 147 分享誰發現圓環脖子的發生的一種直接交互作用澆灌缺乏在樹。此外, 它被觀察, 這種症狀的發展加速在成熟, hass, 果子被拿著在樹直到以下春天。這個期間與對根活動的減少和增加的水耗相符從樹在anthesis.23 期間
