They also studied more than 30 different arabica plants.

他们还研30多种不拉比卡植物。

This is the branch of an arabica coffee tree grown here in Bali.

这是生长在巴厘岛拉比卡咖啡树树枝。

The arabica plant's population changed over thousands of years before humans began growing it.

在人类开始种植拉比卡咖啡树之前数千年里，拉比卡咖啡种群发生变化。

The arabica plants did well during warm, wet periods and suffered through dry ones.

在温暖湿时期，拉比卡植物生长良好，而在干燥时期，它们生长就会受到影响。

Allegedly, Kaldi observed his goats behaving erratically after eating the red berries from a nearby Coffea arabica tree.

据称，卡尔迪观察到他山羊在吃附近咖啡树上红色浆果后行为异常。

The researchers explored the makeup of one arabica variety that is resistant to coffee leaf rust.

研人员一种对咖啡叶锈病有抗性拉比卡品种构成。

Considering bees pollinate Coffea arabica, whose seeds we grind for coffee, you can count that out.

考虑到蜜蜂为拉比卡咖啡授粉，而我们将其种子研磨成咖啡，您可以将其计算在内。

It will grow at nearly seven degrees Celsius higher than arabica coffee.

它生长温度将比拉比卡咖啡高出近七摄氏度。

One of the reasons for that is that it has a much higher caffeine content than the more gentle arabica coffee.

原因之一是它咖啡因含量比更温和拉比卡咖啡高得多。

Exploring arabica's past and present could help give information about how to keep coffee plants healthy – ensuring morning cups of coffee into the future.

索拉比卡过去和现在，有助于提供有关如何保持咖啡植物健康信息，从而确保在未来早晨也能喝到咖啡。

Today, these genetic similarities mean arabica coffee plants are more likely to be hurt by diseases like coffee leaf rust, which causes costly losses every year.

如今，这些基因相似性意味着拉比卡咖啡植物更容易受到咖啡叶锈病等疾病危害，而咖啡叶锈病每年都会造成严重损失。

But it's strong bitter flavor and high caffeine content, almost twice that of arabica, means it's better turned into instant coffee, a process which weakens its flavor and potency.

但它强烈苦味和高咖啡因含量，几乎是拉比卡咖啡两倍，这意味着它最好变成速溶咖啡，这一过程会削弱它味道和效力。
