Why is the seed pod so large for self-pollination of broccoli?
Broccoli self-pollination, big pods, not fruiting, how to return a responsibility? Broccoli belongs to cruciferous crops, and there is often a phenomenon in Cruciferae: self-incompatibility! What do you mean? That is, their own pollen and their own pistil pollination but can not bear fruit.
The phenomenon of self-incompatibility is also very common in cruciferous rape, Chinese cabbage and other crops, and it is often hoped to use stable self-incompatibility lines to produce hybrids in breeding. There are many rape resources of self-incompatibility lines in Fu Tingdong, Academician of Huazhong Agricultural University.
Self-incompatibility is related to temperature, development period and other factors, and self-incompatibility is likely to belong to this situation, so there is no need to make a fuss. If you want to be able to bear fruit, you can cross with the pollen of other plants, if it can bear fruit, then it confirms the above conjecture.
For the larger problem of pods, this is due to the failure to bear fruit, you can pay attention to the fact that pods without pollination are relatively large, after all, plants provide so much nutrition for reproduction, but it is an empty shell. nutrition can only be consumed in the development of the pericarp.
The above situation is only my guess, after all, did not see the photos and the specific operation process, I hope it will be helpful to you.
