Question

Environmental parthenocarpy is triggered by which of the following conditions?

Options

• Low temperature or frost

• High light intensity

• Excessive humidity

• High temperature and drought

Answer 1

Environmental parthenocarpy is triggered by unfavourable environmental conditions like low temperature or frost. These conditions disrupt fertilisation, but auxins still stimulate ovary growth, resulting in seedless fruit development. Some varieties of pear in cold climates exhibit this type.
