Hay fever is only caused by wind-pollinated
plants, like grasses, trees and weeds.
sweetcorn is basically a grass and, as such, it is wind-pollinated
Sweet corn is basically a grass and, as such, it is wind-pollinated
As insect pollinators, bees broaden our diets beyond meats and wind-pollinated
Some wait for insects to come and pollinate them, while other plants need to be wind-pollinated
- and it is this brigade that cause hay fever.
However, brassicas (such as broccoli, cabbage and Brussels sprouts) are not wind-pollinated
In the first region people live among fields of wind-pollinated
crops, whereas the second region is miles away from those fields.
Another example of a mechanism leading to a sequential hermaphrodite through changes in reproductive success can be seen in some wind-pollinated
The key thing is you don't plant them in a straight row because they are wind-pollinated
and the wind will blow the pollen away from the plants.
Grain staples are wind-pollinated
, but most foodstuff that adds vitamins and antioxidants to our diets--apples, pears, cherries, plums, melons, cucumbers, zucchini, almonds, macadamia nuts, and so on--rely on cross pollination.
It's not likely that we would starve to death without pollinators, since most of our calories come from wind-pollinated
or self-pollinated grains like wheat, rice, and corn, but our diets would be vitamin-poor and certainly dull.
The pollens that cause it vary from person to person and from region to region but, generally speaking, it is the tiny pollens of wind-pollinated
plants that are the predominant culprits.
