Seed size influence on germination responses to light and temperature of seven pioneer tree species from the Central Amazon

A implementação de uma modalidade de formação a distância foi um propósito e uma necessidade da Organização Gama que serviu de ponto de partida para o desenvolvimento

Foram adquiridas 16 amostras de goma de tapioca em supermercados e realizados os ensaios para detecção de coliforme termotolerante; Bacillus cereus; Salmonella sp.;

The effect of photoperiod showed that the species need long daily exposures to white light and that shade light inhibited completely seed germination, confirming as pioneer species

Table 1 - Germination frequencies (in %) of seeds from fruits and feces; effects of light intensity (%) and of red/far red ratio in seed germination and duration of dormancy

Seeds of pioneer species, found in the soil seed bank, require light with high fluence and R:FR ratio, high temperature or alternating temperature for

When the seed germination test was conducted at a constant temperature of 25°C without a photoperiod, there was a linear reduction in the cumulative germination of quinoa

hispanica seeds can be carried out between the second (first count) and fifth (last count) days after sowing, given that the conditions that favor the highest germination

Quillaja brasiliensis was tolerant to the sowing methods for germination rate and germination velocity index, and germination rates were similar to the light and
