The plants of the Terena cultivar are of medium vigor, erect, productive, with thorns on the stems, but in lower density than in the Tupy cultivar.
Full bloom occurs in the second half of October and the end of the season is in the last ten days of October or early November. Fruit ripening begins at the end of November or beginning of December, with the average ripening date being November 26, which is approximately 10 days after the start of the Tupy cultivar. The harvest period usually lasts a little over a month, ending in mid-January and, sporadically, until February. The fruits of Terena have a long or oblong shape and, during the ripening process, evolve from pink to bluish-black, with excellent shine, appearance and firmness. The fruits are small to medium-sized, with medium-sized seeds.
In the region of Pelotas, RS, the Terena cultivar has good fruit production, but its yield was lower when compared to the Tupy cultivar during the four years of evaluation in the collection at Embrapa Clima Temperado headquarters. The average yield of the Terena cultivar was 1.2 kg per plant, when planted without the use of espaliers or irrigation, and when the plants were kept less than 1 m high. The average mass of the fruit was 5.5 g, while the fruit of the Tupy cultivar was 5.8 g. However, this difference is offset when assessing suitability for the fresh fruit consumer market.
The fruits of the Terena cultivar have a sweet taste with low acidity and slight bitterness, and an average ratio of over 13 for the four years observed, when measured in frozen fruit. In fresh fruit, Terena had a high soluble solids content, good color, adequate acidity and firmness similar to the Tupy cultivar, and a high soluble solids / titratable acidity ratio, which gives this fruit an excellent flavor. In the 2-year average, the soluble solids content of Terena was 10.3 °Brix, Tupy was 8.9 °Brix and Cainguá was 9.5 °Brix, confirming the suitability of the former for fresh consumption.
With regard to conservation, fruit of this cultivar can be stored for at least 10 days at 1 °C + 90-95% RH, without color reversal and with good quality, with a shine similar to fruit of the Tupy cultivar, but with a small to moderate loss of mass. A percentage of less than 10% of the fruit showed juice leakage. The fact that there was no color reversal is extremely important, as the presence of this defect considerably depreciates the product from a commercial point of view.
The cold requirement of this cultivar is similar to that of the Tupy cultivar. It is therefore suitable for the south and southeast of Brazil and other similar areas.
