After 19 and 67 h of gentle stirring, 50% and 90%, respectively, of the N. peltata seeds had sunk. Few seeds floated again after sinking, but these refloating seeds sank soon with the disturbance. The N. peltata seeds did not germinate without stratification, but the stratification of ...
Small seeds did not germinate but large fresh seeds achieved over 80% germination in laboratory tests. Seeds stored dry for one year did not lose viability. Seedsstored in moist cold conditions (to mimic conditions in the soil over winter) lost viability progressively and none germinated after ...
From our results, it can be seen that pecan seeds germinate best at 30°C, which is a typical high-temperature germination temperature. Temperature not only affects plant growth and flowering, but also plays an important role in seed dormancy and germination [20]. Temperature can induce or rel...
What if my seeds do not germinate Seeds generally take a little longer to grow than seedlings.Most tree seeds will generally sprout within 1 to 3 weeks.If after 4 weeks you don’t see a sprout come through, it is highly likely that your seeds did not germinate.Mother Nature does work i...
Results Germination. In groups of Tf harvested at 2006 i.e., Tf ( 2006), Rw harvested at 2006 and 2003 (Rw 2006 and Rw 2003) of the nested experiment, the seeds did not germinate. Germination also did not occur in treatments 7, 8 and 9 in groups tall fescue harvested at 2014 ...
Nontreated seeds did not germinate at the constant temperatures, suggesting that alternating temperature acts via a GA-independent pathway. Kinetin at 0.1 to 1 mM was no more effective than the control, but a saturated solution of kinetin induced 73% germination. Ethephon at 0.01 to 1 mM ...

Recently dispersed seeds did not germinate because they have primary dormancy. This dormancy was broken after 6 months of burial in the soil. Seeds buried for 10 months entered secondary dormancy and they were not viable at 24 months, probably because of pathogen attack. Considering dormancy and ...
By comparing the seeds with and without damage, it was observed that damaged seeds did not germinate due to total consumption of seed embryo and reserve by seed beetle larvae (Table 1). The low germination rate of seeds with marcescent calyx could have also been caused by the high occurrence...
The first batch of seeds did not germinate and I contacted the company. They sent me a questionnaire and i answered all the questions. I got an email the next day saying they shipped out a new order that very same day. Seeds came within one week. All five seeds germinated and they ...
