Final answer:
The harvesting time for beans varies by type, growing conditions, and harvesting method. Soybeans require shorter days to flower and can be affected by leaf removal and pathogens. Green beans' production is influenced by climate, taking two hours to harvest in France and four in Tunisia.
Step-by-step explanation:
The time it takes from when beans are planted until they are harvested can vary depending on the type of bean, growing conditions, and whether they are harvested as green beans or allowed to dry before harvesting. For example, soybeans, which belong to the pea family (Fabaceae), have a specific growth cycle influenced by the length of the day. Soybean is a short-day plant requiring shorter days to trigger flowering, which is not met near the equator. Depending on the variety and whether they are grown as 'spring wheat' or 'winter wheat,' wheat can be harvested in as little as 100 days after planting.
For green beans, a common vegetable crop, the climate plays an essential role in their growth, as seen in the production rates in France and Tunisia, both of which have Mediterranean climates favorable for these crops. It's important to note that factors like daylength, climate, leaf removal, and plant-pathogen interactions can all influence the growth and harvesting timeline of beans.
