“…Dormant seeds, when dry, slowly lose their dormancy by the process of afterripening. Also, afterripening is well known to alleviate physiological dormancy and promotes germination of many species (BASKIN; BASKIN, 2004). Similar to our results, the previous studies on various species declared that GA 3 treatments could be stimulate the germination and shorten afterripening periods (FEURTADO et al, 2004;LEUBNER-METZGER, 2002;SCHMITZ et al, 2002).…”

ABSTRACT. Seed germination of fig seeds is important for obtain seedlings with high variability in breeding studies, and for producing mosaic virus-free seedlings. This experiment was carried out to evaluated the effects of several treatments (priming with water for 24h, GA 3 at 500 and 1000 ppm for 24h, 3% KNO 3 for 24h, and stratification at 4°C for 7, 14 and 21 days) on seed germination and emergence of 'Bursa Siyahı' and 'Sarılop' fig cultivars. The application of GA 3 increased the germination and emergence of these fig seeds. The highest percentages of germination and emergence were obtained with GA 3 at 500 or 1000 ppm for both cultivars. The seed germination and emergence of the cultivar 'Bursa Siyahı' were higher than observed with the 'Sarılop'. The application of GA 3 at 500 ppm or 1000 ppm reduced the time to germination and emergence from the seeds of both cultivars. In summary, the GA 3 treatments showed efficacy to overcome the dormancy of these fig seeds.

“…In P . mahaleb , the mechanical removal or weakening of the endocarp has been shown to enhance germination, while chemical scarification has led to different results, showing positive and negative effects [ 45 , 46 , 48 ]. Pulp and fruit extracts have been reported to have inhibitory effects on seed germination for other cherries [ 20 , 49 , 50 ].…”

Generalist dispersers promote germination of an alien fleshy-fruited tree invading natural grasslands

Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at the same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very diverse, with positive, neutral or negative consequences for germination and recruitment. Moreover, the environmental conditions where the seeds are deposited and where the post-dispersal processes take place can be crucial for their fate. Prunus mahaleb is a fleshy-fruited tree invading natural grasslands in the Argentine Pampas. In this study, we analyzed the importance of pulp removal, endocarp scarification and the effects of vectors on its germination response, by means of germination experiments both in the laboratory and under semi-natural conditions. Our laboratory results demonstrated that endocarp scarification enhances germination and suggests that vestiges of pulp on the stones have inhibitory effects. Frugivores exert a variety of effects on germination responses and this variation can be explained by their differing influence on pulp removal and endocarp scarification. Most frugivores produced a positive effect on germination under laboratory conditions, in comparison to intact fruits and hand-peeled stones. We observed different degrees of pulp removal from the surface of the stones by the dispersers which was directly correlated to the germination response. On the other hand, all the treatments showed high germination responses under semi-natural conditions suggesting that post-dispersal processes, like seed burial, and the exposure to natural conditions might exert a positive effect on germination response, attenuating the plant's dependence on the dispersers’ gut treatment. Our results highlight the need to consider the whole seed dispersal process and the value of combining laboratory and field tests.

“…The inability of walnut seeds to germinate may be due to the hard seed coat. As the scarification treatment given to the seed helped in uptake of water, growth hormones and air which was required for seed germination (Çetinbaş et al, 2006;Conner, 2008 andAl-Absi, 2010). Prechilling stratification had a significant effect on seed dormancy.…”
