| 词汇 | nematode |
| 词源 | nematode. Beginning gardeners might be puzzled by the term nematode-resistant affixed to many plants, especially to- matoes. A nematode is simply a small, microscopic worm that attacks the roots of plants and often causes great damage. The word is a learned borrowing from the Greek word for “thread” applied to threadlike things such as these unsegmented worms. Some plants have a better ability to repel these worms than oth- ers and are called nematode-resistant. |
