“…Our results showed that moist-chilling treatments induced a great alteration in the level of seed soluble protein. This is strengthened by the findings of Hance and Bevington [34] on sugar maple seeds, Lin et al [35] on pear seeds, El-Refaey and El-Dengawy [35] on loquat seeds and El-Dengawy [26] on peach seeds. Also, Mullen, et al [36] reported that some changes in embryo mRNA populations and synthesized proteins occur during loblolly pine seed stratification, germination and postgerminative growth.…”

The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA 3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilling for 6 weeks at 5 ± 1 °C or for 4 weeks of moist-chilling followed by soaking in 500 ppm GA 3 solution for 24 h. These treatments significantly increased germination percentage and decreased time to 50% germination (T 50) compared to control. Also, the characteristics of the obtained seedlings were much better than those of control. Moreover, the 6-week moist-chilled seeds contained the highest soluble protein concentration. The combination between GA 3 and moist-chilling treatments produced different effects on seed germination, soluble protein depending on the length of the moist-chilling period. GA 3 application on un-chilled seeds improves the germination process. The concentration of soluble inorganic phosphorus of the tested seeds was negative (r = 0.88, p<0.05) while, the concentration of soluble organic phosphorus positively (r = 0.93, P<0.05) correlated with the germination percentage. It was concluded that treatment of moist-chilling for 6 weeks or 4 weeks followed by 500 ppm GA 3 is recommended for promoting the germination process of Ferula ovina seeds and improving growth characteristics of the subsequent seedlings.

“…Some examples of the diversity of physiological effects mediated by TDZ include efficient seed germination, expedited bud break, induction and stimulation of sprouting, cotyledonary growth and development, formation of trichomes and stomata appearance on floral parts and cluster and berry weight of grapes (Babiker et al, 1992;Baskakov et al, 1981;Lin et al, 1994). More recently, the morpho-regulatory potential of the chemical has led to its application in plant cell, tissue and organ culture for the betterment of regeneration protocols.…”

Thidiazuron (TDZ) has gained a considerable attention during past decades due to its efficient role in plant cell and tissue culture. Wide array of physiological responses were observed in response to TDZapplication in different plant species. TDZ has shown both auxin and cytokinin like effects, although, chemically, it is totally different from commonly used auxins and cytokinins. A number of biological (physiological and biochemical) events in cells are induced or enhanced by TDZ, but the mode of action of TDZ is yet unknown. However, varieties of underlying mechanisms were revealed by reports showing how morphogenic events were induced by application of TDZ. Other reports showed that TDZ may modify endogenous plant growth regulators, either directly or indirectly and produce reactions in cell/tissue, necessary for its division/regeneration. Other possibilities include modification in cell membrane, energy levels, nutrient absorption, transport and assimilation, etc. In this review, recent advancements in TDZ application in plant sciences are discussed.

“…Furthermore, according to the findings of Amooaghaie [33] with the forage Ferula ovina, moistchilling treatments induced a great alteration in the level of seed soluble protein and hence seed germination and seedling vigour. This is strengthened by the findings Lin et al [34] on pear seeds and Mullen, et al [35] on Loblolly pine seed stratification, germination and post-germinative growth.…”
