What Squash Will Cross Pollinate With Other Squash?

As we have mentioned, different squash can cross pollinate with each other. The following squashes from each group can cross pollinate with each other.

  • Zucchini, acorn, delicata, pattypan, yellow crookneck, and spaghetti squash. Pumpkins and gourds can also cross pollinate with these groups of squash.
  • Buttercup, butternut, Hubbard, and turban squash.

All these plants can be easily cross pollinated by insects. Their separate male and female flower increase the chances of the female flower becoming fertilized with different pollen grain from a different variety species or the same species. These combinations of plants may end up yielding inedible fruits.

Why Cross Pollinated Squash Tends To Be Toxic?

Normally, the plants of the Cucurbitaceae family are meant to produce a toxic compound which is cucurbitacin. This toxic compound usually acts as a natural defense against insects.

This cucurbitacin toxic compound is present in wild squash, cucumbers, as well as other cucurbits in a substantial amount. So, because of the large amount of cucurbitacin compound in the wild, these types of squash and cucumbers tend to taste very bitter.

However, the domesticated variety often contains a very little amount of this compound that isn’t harmful to the human when consumed. Also, the domesticated squash variety that is grown in the garden and the ones purchased from the stores usually has a less bitter taste. And this is due to the varying amount of bitter compound.

But there are some factors that can cause this bitter and toxic compound to increases its concentration in squash. They are; other product that has been cross pollinated with wild plants and some types of stress during their growth (stress like lack of water or poor fertilization).
