Shoot growth restriction in dry matter partitioning andminituber production of potato plants Ciência Rural
Bisognin,Dilson Antônio; Dellai,Jacso.
The aim of this research was to determine the effect of shoot growth restriction in the dry matter partitioning and minituber production of potato plants grown in a closed soilless system. Minitubers of the cultivars 'Macaca' and 'Asterix' were planted in the greenhouse in the density of 100 hills m-2, during autumn and spring growing seasons. Growth restriction levels were gotten by pruning shoots at 10, 20 and 30cm height or without pruning. The growth restriction levels were identified by their respective leaf area index. The experiment was a factorial (cultivars x growth restriction x growing season) in a random design, with four replications. Growth restriction affected the dry matter production of potato plants in both growing seasons and cultivars....
