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.

Galactomannans from the endosperm of mature seeds of Prosopis affinis were isolated following different extraction procedures in yields of up to 64%. The polysaccharides were characterized by HPLC, GC-MS, and NMR spectroscopy, and their physicochemical properties were studied by SEC/MALLS-QUELS/RI
and rheological methods. The monosaccharide composition of the extracted galactomannans showed only mannose and galactose in a ~1.5 ratio, similar to galactomannans found in guar gum and obtained from other Prosopis species. The structural characterization showed that these polysaccharides are composed by a b-(1/4)-linked mannose backbone with galactopyranosyl residues attached through a (1/6) linkages. The weight-average molecular weight (Mw) of the P. affinis galactomannans went from (1.6 ± 0.2) x 106 to (1.8 ± 0.1) x 106 g/mol, and the intrinsic viscosity, in the 9.9 to 10.7 dL/g range, was comparable to that reported for other extracts from the Prosopis genre. Although the molecular weight distribution and intrinsic viscosity were dependent on the extraction procedure, the mannose-togalactose ratio was almost invariant. Conformation plots showed that the polymer extracted at higher temperatures is more cohesive, a characteristic that could be attributed to a greater number of polymerpolymer interactions. Our findings show that the P. affinis galactomannan has nearly monomodal molecular weight distribution, functional properties similar to those of guar gum, and can be isolated from an abundant and readily available non-traditional source. It therefore represents a promising new biomaterial for the food and pharmaceutical industries that can be produced from the regional native flora in a sustainable way.
