EFFECT OF TOPSOIL STOCKPILING ON THE VIABILITY OF SEED BANK IN FIELD PHYTOPHYSIOGNOMIES CAMPOS DE ALTITUDE.. ABSTRACT: The viability of propagules during topsoil stockpiling is

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

Persistent seed banks are composed of seeds that have more than one year of age and reserves of seeds remain in the soil year after year,generally buried into the soil..

Seedling dynamics – The seedling dynamics of the seed bank naturally stored in the soil was evaluated at the same site used for testing the longevity of seed vi- ability;

To examine the effect of seed burial depth on seedling emergence, 50 seeds were placed on the soil surface or covered to depths of 0.2, 0.5, 1, 2, 4, and 6 cm with the same soil in

The observation that intact seeds were permeable to tetrazolium salt solution in a manner related to germination behaviour of seeds treated with ACC, CEPA or ethylene
