“…The occurrence of frost resulted in a severe reduction of MCD of guapuruvu (vertical arrows in Figure 4c). These results are in agreement with Souza et al (2011) who classified this species as highly sensitive to frost. Despite the high degree of frost damage, this species presented a high degree of regrowth.…”

The appropriate choice of tree species and planting arrangement for use in agroforestry systems is very important in order to maximize productivity and sustainability. The aim of this study was to evaluate the growth of five tree species and its effect on sugarcane yields in different planting arrays in agroforestry systems. The study was conducted from 2007 to 2011 in the city of Frederico Westphalen, RS, Brazil. The five studied tree species were: guapuruvu (Schizolobium parahybae), bracatinga (Mimosa scabrella), canafístula (Peltophorum dubium), angico-vermelho (Parapiptadenia rigida) and eucalypt (Eucalyptus urophylla S.T. Blake x Eucalyptus grandis Hill ex Maiden). Root collar diameter, diameter at breast height, plant height and mean diameter of crown were evaluated for four years with an interval of 90 days between assessments. Yield data for sugarcane were collected in June 2009, 2010, and 2011. Eucalypt presented the greatest root collar diameter values, diameter at breast height, crown development, and plant height. Angico-vermelho, canafístula and eucalypt presented a higher growth in the strip system, while guapuruvu presented the greater growth in the line system. Bracatinga was not influenced by an arrangement in the agroforestry systems. Sugarcane presented greater production in the understory of angico and bracatinga.

“…Parapiptadenia rigida presented a completely damaged leaf area along with 25–49% of necrotic stem, classified as sensitive to frost. Souza et al () classified this species as frost resistant, since they found no visible damage to the aerial part. This divergence may be due to the experimental conditions, considering that the research compared a combination of fast‐growing species.…”

Listing potential species for restoring areas has become a complex task considering the lack of information regarding the silvicultural behavior of native trees after planting and their responses to environmental conditions. Frost is an important meteorological phenomenon that regulates the distribution of plant species, especially in subtropical regions. Thus, we evaluated the effect of frost and the resilience potential of native forest species in restoration planting of a riparian forest in southern Brazil. The experimental design used was randomized blocks in a 6 × 2 factorial scheme (6 species and 2 containers). During the winter in 2014 (270 days after planting), the damage from the impact of frost was assessed through a rating scale ranging from 0 (100% of the leaf area and damaged stem) to 10 (no visual damage). In addition, to assess species resilience, the height and stem diameter were measured, prior to the winter of 2014 and at 270 and 360 days. Eugenia involucrata and Schinus terebinthifolius were considered frost tolerant species. Parapiptadenia rigida was classified as moderately frost tolerant, while Casearia sylvestris, Cupania vernalis, and Inga vera were very sensitive to frost. Casearia sylvestris, E. involucrata, P. rigida, and S. terebinthifolius showed potential for recommencement of growth. On the other hand, C. vernalis and I. vera were considered too sensitive to frost, with high mortality rates and/or no resilience potential.
