gariepinus was mainly divided into three stages; atresia in primary growth phase, atresia in the secondary growth phase and atresia in the maturation and hydration phase.
The oocyte stage diameter range did not vary for any months individually and between reproductive phase, showing constantly prevalence of primary growth oocytes, cortical alveolar stages and secondary growth stages for development and spawning capable phase, and hydrated oocyte for actively spawning reproductive phase (Figure 5).
I was just about to ask Stu if he could see secondary growth when he told me in no uncertain terms to "Shoot that bull now!"
Moreover, decreased activity in GS may also be responsible for increased N[H.sub.4.sup.+] content as it has been shown that accumulation of high concentrations of N[H.sub.4.sup.+] within a cell leads to nutrient deficiency and chlorosis, alters intracellular pH and osmotic balance, inhibits ATP synthesis, and eventually inhibits secondary growth [40].
(3) The spinous process apophyses of the lumbar spine are considered secondary growth centers that do not fuse to the vertebra until age 25.
Metastasis is widely regarded as a selective process inasmuch as the formation of a secondary growth requires that a tumor cell successfully complete each of the abovementioned steps.
Accordingly, assuming that all [Ag.sup.+] ions are reduced to [Ag.sup.0], the increase in the content of silver atoms could start to diminish the ability of CMC to avoid the particles aggregation and its secondary growth. However, in order to know if all silver ions are reduced into [Ag.sup.0] in our samples and to elucidate if this feature diminishes the ability of CMC matrix to avoid the particles aggregation, we proceed to characterize the samples by means of spectroscopic techniques, such as UV-vis and FTIR.
Technologies such as gene mapping, markers assisted selection (MAS), transcriptome profiling, sequencing, gene silencing, and genetic engineering have been used for the identification and validation of candidate genes related to secondary growth and wood formation in both gymnosperms and angiosperms.
The authors point out that palm age is difficult to determine, primarily because palms do not have secondary growth and therefore do not put down annual or seasonal growth rings that can easily be measured.
