英國(guó)學(xué)生科學(xué)讀本 Lesson 68 風(fēng)信子(2)

In the centre of the flower is the green seed-vessel; and if we cut this across, we shall find that it is divided into three parts, each of which contains several young seeds.

位于花朵中間的就是綠色種皮, 我們將其切開(kāi), 就會(huì)發(fā)現(xiàn), 種皮分為三個(gè)部分, 其中每一個(gè)都包含若干小種子。

After the flowers have been open for a few days, the seed-vessels swell and become hard. The rest of the flower then withers away. The seed-vessel turns brown as it ripens, and in autumn it splits open and scatters its little black seeds on the ground. These seeds then take root, and producenew hyacinth plants.

風(fēng)信子的花兒盛開(kāi)幾天之后, 種皮便會(huì)膨脹, 變硬, 花朵的其他部分則逐漸枯萎。種皮成熟之后變成棕色, 到了春天, 種皮裂開(kāi), 于是, 里面的黑色種子落到了地上。隨后, 這些種子生根發(fā)芽, 成長(zhǎng)為新的風(fēng)信子。

What is the use of its bulb to the hyacinth? The bulb is a kind of store-house, in which the plant lays up food during the summer, so that it may be able to grow quickly, and to flower early in the next spring. As the leaves and flowers grow, they use up all the food contained in the bulb, and it slowly wastes away.

風(fēng)信子的球莖有什么用呢? 它就像是一個(gè)儲(chǔ)藏室, 可以讓風(fēng)信子在夏天的時(shí)候儲(chǔ)備食物, 從而讓自己快速生長(zhǎng), 在來(lái)年的春季早一些盛開(kāi)花朵。隨著葉子與花朵的生長(zhǎng), 風(fēng)信子會(huì)把球莖中儲(chǔ)存的養(yǎng)分全部消耗完畢, 球莖也就逐漸失去了作用。

But after the flowers have ripened and formed their seeds, the plant sets to work to make a new bulb, either above or on one side of the old one. Thus the same hyacinth plant grows on in the ground year after year, forming a new bulb every year.

然而, 當(dāng)花朵成熟, 形成種子時(shí), 原有的球莖上方或者一邊就會(huì)長(zhǎng)出新的球莖。因此, 年復(fù)一年, 新的球莖總是能夠在原地生長(zhǎng)成為另外一株風(fēng)信子。

Did you ever buy hyacinth bulbs to grow in pots or glasses, or in your garden? Such hyacinths are somewhat different from the wild ones. Their six petals are joined together, except at the tips. The flowers are crowded more closely together on the flower-stalk than they are in the wild hyacinth, and are of more varied colours. I hope that you will one day try to grow a hyacinth in a glass of water.

你是否買過(guò)風(fēng)信子球莖, 種植在花盆、玻璃瓶或花園之中? 這些風(fēng)信子與野生的有所不同。六個(gè)花瓣除了頂部, 其余部分全部連接在一起。與野生風(fēng)信子相比, 家養(yǎng)風(fēng)信子花莖上的花朵彼此依靠得更加緊密, 而且顏色更加豐富。希望有一天你們可以親手在一杯水中栽種一株風(fēng)信子。
