Genetic improvement programs for pear trees in Brazil are characterized by rootstock (hypobiotic) selection mainly considering physiological attributes such as vigor, breakage of dormancy, propagation easiness, and sanitary characteristics, such as resistance to pests and diseases. However, kinetic parameters that determine nutrient uptake efficiency are not usually considered as, for example, nitrogen (N) in forms of NO3 − and NH4 +. The objective of this study was to evaluate the kinetic parameters related to N uptake in pear selection '54′ and '971′ as additional criteria for rootstock selection. The plants were acclimatized in a half-strength Hoagland solution and tested to assess the depletion of the internal reserves at 15 and 30 days, in CaSO4 solution to evaluate the depletion period during 65 h. The selection '971′ showed more significant NO3 − and NH4 + uptake efficiency, because presented higher Vmax values and Influx. The internal reserve depletion (IRD) period for the evaluated selections was 30 days in CaSO4 solution. The evaluation period of the depletion period to reach the Cmin for selections '971′ and '54′ was 64 and 65 h for NO3 − respectively, and 65 h for NH4 +. The selection '971′ had a higher affinity with the NO3 − ion when correlated with the physiological parameters of minimum fluorescence (Fo) and electron transport rate (ETRm). |
