Potato stolon growth?
Do stolons continue to grow (either new stolons or the elongation of existing stolons) throughout the growing season, or does their development end after the plant's foliage has been established and it begins making tubers?
I have read that indeterminate varieties can indeed make new stolons post-foliage-establishment, if they're continuously hilled, like in a potato tower. Determinate varieties were (supposedly) bred to not be able to develop stolons and set tubers continuously upwards from the main stem, because that'd mean constant hilling up for commercial operations in order to prevent tuber sun exposure. So basically from what I can gather, determinate varieties tend to set tubers below the seed piece, and indeterminates set them above the seed piece.
Also, is there any reason why longer stolons would be desirable towards a higher yield? Does that mean there is more room for larger potatoes and more stolons to grow? Or are longer stolons simply a characteristic of directly Peruvian-descended taters, which has been bred out of determinate cultivars for an easier harvest?
Any thoughts about stolon growth in both indeterminate and determinate cultivars?? I'm actually trying to uncover why there might be so much controversy surrounding potato towers. So any related thoughts you have would be much appreciated.
