Nitrogen uptake and growth of Pinus greggii Engelm. six years after chemical root pruning

, : Nitrogen uptake and growth of Pinus greggii Engelm. six years after chemical root pruning. Agrociencia Montecillo 41(6): 675-685

Chemical root pruning is a cultural practice in nurseries to improve fibrousness of the root system, among other purposes. In this study nitrogen uptake was quantified in Pinus greggii Engelm. six years after chemical root pruning was applied in a nursery. The treatments were: bag and carpet impregnated with copper (T1); bag impregnated with copper (T2); carpet impregnated with copper (T3); bag without impregnated copper (T4, control).

White light (WL) inhibited the stem elongation of etiolated pea (Pisum sativum L.) seedlings and the inhibition was partially reversed by the application of gibberellin A1 (GA1), the active GA in shoot growth. The amount of GA1 in the apical shoot...
