“…On the other hand, Ghayyad et al (2010) reported that the GA 3 pretreatment alone gave better results with respect to germination of P. mahaleb seeds without endocarp, than the GA 3 pretreatment followed by a 10-week period of CS. Also, Zeinalabedini et al (2009) observed that the combination of stratification (at 4ºC) with GA 3 pretreatment (1000 ppm for 30 minutes) did not improve germination of seeds without endocarp in three wild almonds species. This difference may be due to the different time of GA 3 pretreatment.…”

“…This difference may be due to the different time of GA 3 pretreatment. In our study, P. mahaleb seeds without endocarp were pretreated with GA 3 for 24 hours, in contrast to the method followed by Zeinalabedini et al (2009), who pretreated seeds of the three wild almonds species without endocarp with GA 3 for 30 minutes.…”

“…Ghayyad et al (2010) obtained the best results in germination of P. mahaleb seeds by removing the endocarp and then applying GA 3 . Also, exogenous applications of GA 3 and H 2 O 2 prior to CS have been reported to improve germination in Prunus species seeds without endocarp (Imani et al, 2011;Zeinalabedini et al, 2009).…”

Sexual propagation of Prunus mahaleb is difficult due to seed dormancy. To overcome dormancy and maximize germination, various pretreatments have been applied, including stratification (warm and cold), gibberellic acid (GA 3 ), sulfuric acid scarification (AS), and endocarp removal. The results show that warm stratification (WS) prior to cold stratification (CS) does not improve seed germination and a long period of WS (3 months) is disastrous for germination. CS alone (up to 4 months) has been found to hasten and increase seed germination. Pretreatment of the seeds with exogenous GA 3 , during the CS period, has been observed to result in significantly higher seed germination. AS of seeds for 45 minutes prior to GA 3 (1000 ppm for 24 hours) plus CS (up to 1 month) pretreatment has been considered to reduce the mechanical resistance of endocarp and improve germination. However, extended time of AS (180 minutes) prior to GA 3 plus CS pretreatment has been found to harm the seeds. The removal of endocarp has been noted to significantly improve germination. Seeds without endocarp, which were pretreated with GA 3 (1000 or 2000 ppm for 24 hours) and then cold stratified for 1 month, have been noted to exhibit the highest germination percentages.

“…1 Many works have reported that exogenous application of H 2 O 2 can improve seed germination in many plant species. [10][11][12] The interplay between ROS and hormone signaling pathways lead to changes in gene expression or in cellular redox status that would play a role in the perception of environmental factors by seeds during their germination.…”

“…Germination starts with the uptake of water by the seed-imbibition process and is finished when a part of the embryo, usually the radicle, extends to enter the structures that surround it. Since GA 3 has been shown to be a key factor in monitoring seed dormancy and germination in many plant species together with potatoes [34,2,31,12,24,5], GA 3 is frequently used to break seed dormancy and to increase seed germination in many plant species [3,36,23,6,11,37].

Sweet potato is an herbaceous, perennial plant belonging to the Convolvulaceae family with a critical role in the global food system, particularly in the developing world, where they rank among the top 10 food crops. Germination of sweet potato seeds is difficult due to thick, very hard and impermeable testa. In order to study the germination rate, seeds were exposed to different treatments such as effect of gibberellic acid, water and acid treatment along with control. The seeds were soaked in water for 24 hrs, 48 hrs, different concentration of GA 3 (50, 100 and 250 ppm) at different time intervals (10, 30, 60 minutes) and acid scarification (sulphuric acid) of seeds for 5, 10 and 15 minutes. All the 15 treatments along with the control were kept for germination in moist petriplate in dark and allowed to germinate. The rate of seed germination was recorded every day and after 5 days maximum seed germination was observed in acid treatment 75-80 % followed by 50 ppm GA 3 for 30 and 10 minutes. From the result it was concluded that the acid treated seeds showed maximum seed germination when compared to other treatments.
