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.
Germinated seeds with 1, 2, 3, 4 and 5 mm radicle lengths were subjected to dehydration at 25[degrees]C in the dark in sealed plastic boxes with activated silica gel on the bottom, which generated a relative humidity of 8%.
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).
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.
