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.
In many species, strong asymmetrical growth in the lower scutellum and coleoptile
region of the proembryo displaces the root cap and plumule away from their original basal and lateral position (Goetghebeur 1986).

For the variables coleoptile
length (CL) and radicle length (CR), the results showed no differences between treatments.
The experiment was performed in triplicate with 5 coleoptile
fragments and 2 mL of extract, control solution or oxyfluorfen.
According to our results, the growth of roots and coleoptile
is also affected by the duration of storage, the latter driving a decrease in growth of aerial parts and root for both varieties studied.
The compounds exhibited either stimulant or inhibitory effects on germination and on radicle and coleoptile
growth, depending on the formulation tested.
tiller development is associated with fast early vigor in wheat.
It also has the capacity to bind to fractions containing plasma membrane vesicles from maize coleoptiles
An increased number of cell layers in the scutellum and other stages of embryonic development were observed when the coleoptile
emerged (Figure 5F).

Previous studies have shown that greenbug populations collected from very contrasting ecological regions of Argentina showed significant differences in reproduction behavior, lifespan, host preference (Ramos et al., 1998; Clua et al., 2004), even the genetic variation of aphid aggressiveness has been studied among biotypes by means of the coleoptile
tests (Gimenez et al., 1991a, b, 1992; Castro, 1994; Castro et al., 1991).
