| ABSTRACT The tetrazolium test is one of the promising alternatives to determine the viability of dormant, recalcitrant and slow-germinating seeds. The objective of this study was to adapt the tetrazolium test methodology to estimate the viability and vigor of Piptadenia stipulacea (Benth.) Ducke seeds. For this, a sample of seeds was classified into three sublots using round sieves, corresponding to six, five and four millimeters in diameter, respectively. Moisture content, imbibition curve, germination, emergence, germination and emergence speed indices, mean germination time and seedling emergence were initially evaluated. The second stage was conducted using a completely randomized experimental design, in 3 x 9 factorial scheme, corresponding to three... |

| The present study aimed to evaluate the safety of the alcoholic leaves extract of Reinwardtia indica in Charles foster rats through an acute and sub-acute oral administration.For assessment of acute oral toxicity test, ratswere orally treated with single dose of the alcoholic leaves extract of Reinwardtia indica at the doses of 50, 250, 500, 1000 2000 and 5000 mg/kg. In sub-acute toxicity study, using the OECD guidelines no. 407, the extract was administered at the doses of 50, 250, 500, 1000, 2000 mg/kg/day for 28 consecutive days and at the dose of 2000 mg/kg satellite group also used for 6 weeks.In acute toxicity above mentioned doses neither showed mortality nor exterior signs of toxicity. In sub-acute, study no significant changes found in... |
