Table 1--Results from the analysis of variance for electrical conductivity, seed moisture content, first germination count, germination, radicle and seedling lengths, emergence speed index, and emergence of Urochloa Brizantha cv.
There was a significant interaction within the factors cutting length x time of the year x IBA concentration with the jabuticabeira of cabinho concerning the rooting (%) (Table 1), between the IBA concentration x time of the year for the average number of radicles per mini-cutting (Table 3), for the cutting length x IBA concentration in the average length of radicles (Figure 1) and in the interaction cutting length x time of the year in the variables average radicle length and survival post-transplantation (%) (Table 4) and in the factors times of the year (Table 2) and IBA concentration (Figure 2) for callogenesis (%).
olitorius (leaf biomass, hypocotyl biomass and radicle biomass) significantly affected by salinity summarized in Tables 2 and 3.
Germination was considered when radicle was extended to at least one mm.
The highest tested concentration of sucrose produced the highest frequency of plantlets bearing developed shoots and radicles. After four months in the greenhouse, plants grown solely in horticulture compost displayed simultaneously higher number of leaves and longer roots.
germination of the seeds exposed to the semi-coke water extract was later possible in water and the emerged seeds also showed radicles. The stronger water extract (L/S = 0.8) had toxic non-reversible effect on seeds, after-germination in water was not achieved.
The seeds were oriented with the radicle down and the units were held in a vertical position at 25[degrees]C in a humid, ethylene-free atmosphere until the radicles reached the appropriate length (i.e., 1, 10, 20, and 30 mm).
The radicles of seedlings imbibed in pH 6.0 and pH 7.0 buffers showed no signs of browning or weak growth.
Under our bioassay conditions, radicles emerge from seeds beginning 3 d after exposure to smoke extracts (Day 0).
Fresh organs (cotyledons, hypocotyls or radicles) were ground at 4oC in 0.1 M sodium borate buffer (pH 8.8).
