The exception is one study in the Netherlandsâthe Netherlands Cohort Study on Diet and Cancerâin which women (but not men) who had a high intake of cruciferous vegetables had a reduced risk of colon (but not rectal) cancer (12).
Crops: beans, celery, corn, cucumbers, New Zealand spinach, and summer squash. Temperatures: Tender vegetables grow with daytime temperatures above 55Â°F, and are intolerant of frost. When to plant: 1  Based on soil temperature, refer to Table 2.2  Soil is adequately dry to work.3  These crops may be planted (from seed) around the date of the average last spring frost.emperatures: Very tender vegetables are not only intolerant of frost, but also cool spring winds. They need daytime temperatures above 60Â°F, and prefer temperatures of 70Â°F to 95Â°F. A week of daytime temperatures below 55Â°F may stunt the crop.
Cotton plants can attain a height of 15 to 20 feet. Under ideal growing conditions, the temperature should hover between 90 to 95 degrees Fahrenheit. The plant develops a deep and extensive root system that makes it drought tolerant. The roots can grow as much as 1/2 inch per day, according to the University of Florida IFAS Extension. If the temperature dips below 60 degrees or above 100 degrees, the growth of the plant slows or ceases. High nighttime temperatures above 85 degrees can render the plant sterile.
