Scanning electron micrographs of
radicle cells of Anadenanthera colubrina embryo axis.
For the variables coleoptile length (CL) and
radicle length (CR), the results showed no differences between treatments.
virens with high plumule length upto 13.3, 12.7 and 12.4 cm and
radicle length upto 6.2, 5.6 and 5.3 cm respectively.
Seeds were considered to be germinated at the emergence of the
radicle and scored.
Daily monitoring of the samples were done and the number of seeds germinated with
radicle length of 1-2 mm were counted and recorded at the same time of the day and to the end of the experiments on the eighth day.
Besides, gibberellin has an important role in the activation and/or synthesis of enzymes that promote the weakening of the tissues which surround the embryo, facilitating the
radicle protrusion (OGAWA et al., 2003).
The seeds were considered to have germinated after
radicle emergence.
For cultivation in sucrose-containing media the average values observed for
radicle (n = 45, F = 5.441, p = 0.010) and shoot (n = 45, F = 21.899, p < 0.001) emergence were highest for the highest concentration tested.
2006).Moreover, germination/emergence and seedling growth was improved by the application of Zn in priming solution(Tables 1-4)as Zn is involved in the
radicle development and in the early stages of coleoptile growth and in auxin synthesis (Ozturket al.
It cleanses and degrades any unwanted
radicle present in the body.
Seeds were considered germinated when
radicle was longer than 5.0 mm.
