Any tomato can grow an extra locule.

任何番都可能会长出额外的子。

Temperatures over 32 degrees Celsius during the day and 27 overnight can lead the tomato to form an extra locule.

天气温超过32摄氏度，夜间气温超过27摄氏度，会导致番形成额外的子。

The likelihood of one of your tomatoes developing a locule oddity is estimated to be about one in a thousand, McDermott said.

麦克德莫特说，据估计，番子畸形的可能性约为千分之一。

If you have ever cut open a tomato, you know they are divided into internal parts, called locules, which contain seeds and a substance called gel.

如果你曾经切开过番，你就会知道它们被分成内部部分，称为子，里面含有种子和一种叫做胶体的物质。
