ABSTRACT.
?Williams B.C.? pear was grafted on two pear rootstocks: ?Farold®40? and ?Farold®69?, and on three clonal quince rootstocks: ?BA 29?, ?Adams? and ?EMC? with and without ?Beurré Hardy? as an interstem. To evaluate the performance of these combinations in the south of Uruguay, grafted trees were planted in 2003 at INIA Las Brujas, ?Wilson Ferreira Aldunate? Experimental Station (34°40 S-56°20 W). Rows were 4.5 m apart and variable distance was used between plants according to rootstock: 1.70 m (?BA29?, ?Farold®40? and ?Farold®69?), 1.50 m (?Adams?), and 1.30 m (?EMC?). Observations on phenological, vegetative, and productive behavior of the ?Williams B.C.? scions were carried out each year. From 2004 onwards, trunk cross-sectional areas (TCSA) showed differences allowing rootstocks to be ranked in order of decreasing vigor: > ?Farold®69? > ?Farold®40? > ?BA 29? > ?Adams? > ?EMC?. In 2014, trunk cross-sectional area on ?Farold®69? was 198.7 cm2 while a minimum of 53.8 cm2 was measured on ?EMC?. Different rate of plant death occurred, having higher losses among ?EMC? and ?Adams? with interstem and all quince rootstocks without interstem. Cumulative fruit yields per plant of nine harvests ranged between 149.8 (?BA29? with interstem) and 73.5 kg tree-1 (?EMC?). The best performances were recorded on ?BA29? with interstem, ?Farold®40? and ?Farold®69? pear rootstocks, with an average of cumulative production of 190 ton ha-1. The highest yield efficiency was obtained with ?Farold®40? rootstock (0.35 kg cm-2 TCSA) and with ?BA29? with interstem
(0.30 kg cm-2 TCSA). Therefore, to achieve maximum pear production potential under Uruguayan conditions, rootstock quince ?BA29? with ?Beurré Hardy? as an
interstem, ?Farold®40?, and ?Farold®69? are the better options. MenosABSTRACT.

ABSTRACT.- Flower induction and differentiation are complex phenomenon not fully understood in pear trees. Paclobutrazol (Pbz), Ethephon (Eth), and naphthaleneacetic acid (NAA) exogenous applications could be potential tools to increase return bloom and yield, and to manage the alternate bearing in some pear cultivars. The objective of this research was to evaluate the effect of Eth, Pbz, and NAA on return bloom and yield of 'Rocha' pear trees in different climatic conditions of Southern Brazil. The experiments were performed during 2015/2016-2017/2018 growing seasons, in Sao Joaquim, Santa Catarina State, and during 2015/2016-2016/2017 growing seasons in Antonio Prado, Rio Grande do Sul State. The pear 'Rocha' were grafted on quince rootstock 'BA29' (experiment 1 and 3) and Pyrus calleryana (experiment 2). Treatments consisted of Eth, Pbz, NAA, and Eth + NAA sprayed at different concentrations and timings. Shoot length, pruning weight, fruit set, number of thinned fruit and total fruit per tree, yield, average fruit weight, flesh firmness, and soluble solids content were assessed. Shoot length decreased, whereas return bloom and yield components increased when using Eth, Pbz, and Eth + NAA in all experiments. However, the positive effect is only in the rate of 10 mg L-1 NAA in experiment 1. Fruit size was reduced in Eth concentrations above 300 mg L-1, as a direct effect of crop load. Our results show that Eth and Pbz increase return bloom and yield of 'Rocha' pear trees being a potential tool to improve flowering in warm winter Regions as Southern Brazil. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
