“…Berg.) Burret is a native species of the south of Brazil, argentina, uruguay, and Paraguay (MattOS, 1986;1990), it is popular known as pineapple guava, guavasteen or feijoa (DONazzOLO et al, 2015). the pulp is cream colored, has a distinctive sweet-acidulated and aromatic flavor (MATTOS, 1986;DUCROQUET et al, 2000).…”

-Phenotypic studies with native fruits are important sources of information for understanding the status of conservation of plant species, especially populations in protected areas (Pas). Fruits of 18 populations of feijoa [Acca sellowiana (O. Berg.) Burret] present in three kind of Pas, Quilombolas communities (QLs), Indigenous Lands (ILs) and conservation units (cus) were evaluated with the aim to characterize the phenotypic variability. Fruits were harvested at maturity and eight morphological descriptors were measured: diameter, length, total weight, pericarp weight, pulp weight, pericarp thickness, pulp yield and solid soluble contents (°Brix). the results revealed the existence of large morphological variability for all traits, with significant differences among all populations and among those populations grouped in QLs, TIs and UCs, particularly to the total weight and peel thickness. There was a clear formation of five major clusters of genetic dissimilarity. In addition, two uruguayan type populations and 16 Brazilian type populations showed contrast means for most of the evaluated traits. the lower variability on fruit characters found in plants collected in areas of traditional people but not in cus suggests the existence of selection processes of feijoa genotypes on those areas. Index terms: Goiabeira-serrana, pineapple-guava, traditional people, in situ on farm conservation. VARIABILIDADE FENOTÍPICA EM FRUTOS DE GOIABEIRA-SERRANA [Acca sellowiana (O. Berg.) Burret] EM TERRAS INDÍGENAS, COMUNIDADES QUILOMBOLAS E EM UNIDADES DE CONSERVAÇÃO NO SUL DO BRASILRESUMO -estudos fenotípicos com frutas silvestres são importantes fontes de informação para entendimento do estado de conservação das espécies vegetais, sobretudo em populações de plantas em áreas protegidas. Frutos de 18 populações de goiabeira-serrana [Acca sellowiana (O. Berg.) Burret], internacionalmente denominada de feijoa, presentes em comunidades Quilombolas (QLs), terras Indígenas (tIs) e em unidades de conservação (ucs) foram avaliados, com o objetivo de caracterizar variabilidade fenotípica. Os frutos foram coletados na maturação, e oito características foram avaliadas: diâmetro, comprimento e peso do fruto, peso da casca, peso de polpa, espessura da casca, rendimento de polpa e teor de sólidos solúveis totais (°Brix). Os resultados revelaram a existência de significativa variabilidade morfológica para todas as características avaliadas, havendo diferenças significativas entre todas as populações e entre as -agrupadas em QLs, TIs e ucs, em especial para o peso total e a espessura da casca. houve clara formação de cinco grupos principais de dissimilaridade, com separação de duas populações para o tipo uruguai e 16 para tipo Brasil. O fato da ocorrência da menor variabilidade nos frutos encontrado em plantas de áreas de povos tradicionais, sugere a existência de processos de seleção de genótipos da goiabeira-serrana nestas áreas. Termos para indexação: Feijoa, pineaple-guava, povos tradicionais, conservação in situ on farm.

“…Studies aiming to understand behavior of seeds during storage involving native species have enabled the proper management of seed batches (Donazzolo et al, 2015). Considering that not all seeds are tolerant to desiccation, prior knowledge on physiological behavior is necessary for successful conservation (Marques et al, 2019).…”

“…It also has the peculiarity of presenting edible petals (Mattos, 1986) and important characteristics for ornamental use (Gomes et al, 2017) and is recommended for the recovery of affected ecosystems (Fockink et al, 2020) also in Pharmacology (Santos et al, 2019). In this way, the use of this species tends to increase and the knowledge about the behavior concerning desiccation and longevity of seeds is of great importance, especially for the conservation of germplasm for future use (Donazzolo et al, 2015) and use in genetic improvement (Gomes et al, 2013).

The objective of this paper was to determine the physiological behavior and seed quality of five genotypes of Acca sellowiana regarding desiccation. Seeds were obtained from five plants of urban backyards in the cities of Dois Vizinhos - PR (A1, A2) and Vacaria - RS (A3, A4, A5). The experiment was conducted in a bifactor arrangement (5x3), with five genotypes and three levels of water content (28%, 15% and 5%), arranged into complete randomized block design, with four replicates of 50 seeds each. Seeds were germinated on absorbent paper soaked with water, being kept in BOD chamber under temperature of 25±3°C with photoperiod of 16 hours. Germination percentage, speed index and average time were assessed by counting seeds every two days for 50 days, starting from the moment of radicle emergence. No significant differences were observed for germination percentage and all genotypes surpassing 79% of germination. Desiccation of seeds had low influence on germination speed index and average time of germination, although genotype influence was verified due to genetic variability. Genotype A5 has seeds with superior quality from the others. Acca sellowiana seeds have orthodox behavior.

“…Feijoa (Acca sellowiana (O. Berg) Burret) is a fruit tree native to the highlands of Southern Brazil and Northeastern Uruguay and it has spread worldwide over the last 100 years (Sharpe et al, 1993). In Brazil the cultivated area of feijoa is increasing (Donazzolo et al, 2015), with cultivars having been created (Ducroquet et al, 2007(Ducroquet et al, , 2008. However, feijoa trees have shown good adaptability to subtropical regions and are also cultivated in the United States of America, New Zealand, Colombia, Australia, Turkey, and China (Thorp & Bieleski, 2002;Beyhan & Eyduran, 2011;Xiong et al, 2016).…”

Leaf area (cm2 per leaf) and leaf pigment content are important traits that can be used to better understand a plants physiology. In this study, empirical non-destructive models for leaf area and leaf pigment based on the leaf dimensions, length (L) and width (W) in centimeters, and chlorophyll meter readings were developed for feijoa (Acca sellowiana). The experiment was carried out during January 2016 using five-year-old trees of 60 genotypes, grown under field conditions in the state of Paraná, Brazil. The proposed leaf area (LA) model was L A = 0 . 0022 L 3 + 0 . 1482 W 2 + 0 . 6159 L W + 0 . 1076 (R2 = 0.99). Three current leaf area models found in the literature were also assessed. All of the already created models were less accurate than the model proposed in this article. The proposed leaf pigment models were based on the Falker Chlorophyll Index for Chlorophyll a (A) and b (B), these were C h l a = 2 . 564 A + 13 . 098 B - 42 . 605 (R2 = 0.94), C h l b = 1 . 538 A + 3 . 287 B + 8 . 847 (R2 = 0.86) and C a r o t e n o i d s = 0 . 947 B + 8 . 943 (R2 = 0.88) expressed as µmol m-2 of leaf blade. In conclusion, the proposed models in this study were shown to be a reliable non-destructivel way of estimating A. sellowiana leaf area and leaf pigment.
