Luz e temperaturas na germinação de sementes de Sinningia leucotricha

Abstract: A Sinningia leucotricha é muito utilizada como planta ornamental e devido à exploração desenfreada encontra-se em risco de extinção. O trabalho teve por objetivo avaliar o efeito da luz e diferentes temperaturas na germinação de sementes de rainha do abismo. As sementes retiradas de frutos maduros foram submetidas a presença e a ausência de luminosidades e a diferentes temperaturas (15, 20, 25, 30 e 35°C), o delineamento experimental foi o inteiramente casualizado, em esquema fatorial 2X5 com quatro repetições… Show more

“…Seeds of Murdannia nudiflora promoted greater germination when submitted to light and at temperatures of 25 and 30°C (LUZ et al, 2014). There was an interaction between the temperature and luminosity for the germination of Sinningia leucotricha (Hoehne) Moore (MORITZ et al, 2015). Table 2 shows the results for the vigor of seeds evaluated by the first germination count, in which Light 25 30 20-30 White 43aC 7aA 54bB Green 33bC 4cB 64aA Red 33bC 64bA 55bB Far red 21dB 63bA 63aA Dark 29cA 25dA 25cA Means followed by the same letter, lowercase in the column and upper case in the row, do not differ statistically from each other, a 5% probability by the Scott-Knott test.…”
