In 2018, at beginning of blooming stage of seven blackberry genotypes (cultivars BRS Xingu, BRS Cainguá, Tupy and Brazos and the selections Black 139, Black 198, and Black 254) plants were exposed to three temperature regimes for four days (control - plants kept constantly at 20 ± 1 ºC; plants held at 29 ± 1 ºC, during the day (light period) and 19 ± 1 °C, at night; and plants constantly held at 30 ± 1 °C) aiming to test heat tolerance of blackberry flowers. Pollen germination, average number of drupelets per fruit, photosynthetic electron transport rate and electron losses in the leaves were evaluated. Based on the results we concluded `BRS Cainguá´ released by Embrapa in 2019, was among the most tolerant to heat conditions whereas selection Black 254 was the most sensitive. |
