Resumo: |
The studies were carried out in the Laboratory of Seed Analysis and greenhouse, of Universidade Federal Rural de Pernambuco, Unidade Acadêmica de Garanhuns (UFRPE/UAG), from Garanhuns-PE. The work were realized with seeds of Schinus terebinthifolius Raddi, aiming to describing and illustrating morphological aspects of seed, development of seedlings and plants, as well as evaluate the effect of temperature and light scheme sob the physiological quality of seeds. In the first experiment was carried out morphological description and illustration of seeds, seedlings and plants. The second experiment was used a completely randomized design in factorial of 4 x 6, four light scheme (white, red, far-red and dark) at six temperatures 15, 20, 20-30, 25, 30 and 35ºC. The size of the seeds of S. terebinthifolius varies from globular to reniform, the coat is rough wavy, glabrous and dark brown. Germination is epigeal phanerocotylar slow and uneven, beginning on the fifth day after sowing extending until the 14th day. The plant is heterophile, initially protophilus are simple, opposite, and after 40 days the metaphylls compounds are trifoliolate, alternate and opposite. The seeds are classified as neutral photoblastic, and for the best expression of its physiological quality should be submitted to a constants temperatures of 25ºC and of 20-30ºC alternating in the light scheme of write, 20 and 30ºC in red light and and 20ºC in far-red light. |
