The test consisted of treatments without and with seed dormancy
break, which was obtained through seed immersion for 60 seconds in water heated at 100[degrees]C (Smiderle, Mourao Junior, & Sousa 2005).
Scarification is a largely employed method because it works changing the nature and level of the promoter and inhibitor hormones involved on the processes of seed dormancy
and germination (CAMPANA et al.
The understanding of the dormancy
dynamics of a particular commercial cultivar in its environment is important because it allows a planning that makes the application of diverse cultural practices such as pruning, thinning, fertilization and application of products for the breakdown of dormancy
in mango plants is caused by external or internal factors and farmers must take care of food requirements of plants, water application, counter diseases and pests and save plants from frost.
2], even after the stress process, was able to break dormancy
It was reported that dormant seeds which require chilling dry storage after ripening and light as a germination stimulator are often treated with GA3 to overcome their dormancy
This is partly because seeds shed in the autumn are mostly dormant and require a period of cold-stratification satisfied under snow before they germinate in spring (see below) and partly due to the ability of the seeds to re-enter dormancy
(in the case of PD) if they did not germinate.
The transfer of unexercised gift certificates, gift cards, and merchandise credits potentially allows the transferor to avoid having these items become escheatable, provided that they are transferred prior to the expiration of the dormancy
In third-stage dormancy
, as the cold temperatures intensify, the fluid remaining in cells turns into antifreeze, thus ensuring strong resistance to cold damage.
Generally, the seeds tend to be dormant in low temperature and long photoperiod, but sometimes the low temperature and high moisture would break dormancy
and promote the seed sprouting (Argel et al.
As a contribution to the Recovery Plan for Narcissus alcaracensis, we investigated several traits of seed dormancy
and germination ecology.
The research was carried out to investigate best method for breaking seed dormancy
of sunflower with different treatments in darkness and light.
