The word “dormancy” refers to the temporary stop of plant growth. It comprises true dormancy, known as (“rest” or “endodormancy”) triggered by internal factors and climatic dormancy (“quiescence” or “ecodormancy”) controlled by external factors [
198]. As mentioned by reference [
194], dormancy and the breaking of dormancy in buds of bamboos vary with their position on the plant, the season of the year and the species, while seed dormancy is known to occur in many tropical tree species. In seeds, several methods are known to be involved in the induction of dormancy to the germinating state. In this section, the role of plant hormones, various treatments available are discussed for bamboo seed dormancy. Important factors influencing seed germination include the seed quality and their viability. Major causes linked to the loss of seed viability are the endogenous levels of auxins and abscisic acid (ABA) during prolonged storage [
199]. Besides, bamboo seeds are short-lived, germinate within 3–7 days and the germination potential is season-dependent [
200]. To preserve the viability for a longer period of time, seeds are usually stored at 4 °C in desiccators with anhydrous calcium chloride. Furthermore, reference [
201] revealed that prechilling the seeds (4 to 5 °C) for 4 weeks could be the most effective way to extend their life. This process is known as vernalization, and it involves exposing seeds to low temperatures in order to stimulate or to enhance seed development [
198]. For instance, reference [
106] stored
D. asper seeds at 4 °C for 3 months before undergoing surface sterilization. However, degradation can occur during storage. Depending on the predominant causes of dormancy, some authors [
202,
203,
204] have suggested various approaches to break the seed dormancy in order to improve the germination rate and speed up the germination process. Besides, the breaking of seed dormancy varies from species to species. Therefore, it is very important to determine which method and condition are the best for each plant species. Various techniques are available that enhance the vigor of seeds, and these technologies are termed as seed invigoration/seed enhancement techniques [
205]. Seed invigoration is a postharvest treatment that enhances seed production by ameliorating the germinability, storability and yield performance of the seeds [
199]. Hydropriming, seed hardening, on-farm priming, osmo-priming, osmo-hardening, humidification, priming with plant growth regulators, polyamines, ascorbate, salicylate, ethanol, osmolytes, coating technologies and, more recently, pre-sowing dry heat treatments are some of the treatments used to invigorate seeds [
200]. These strategies provide high-value crops with value-added solutions that improve the yield and quality. Generating greater emergence rates, rapid seedling growth and better stand developmental rates are the results of seeds priming [
206]. However, no treatments have been applied to
D. asper seeds in order to break their dormancy and improve their viability. In terms of plant growth regulators, reference [
207] indicated that the major gibberellins formed by the germinating embryo are GA
1 and GA
3. Furthermore, GA
3 and GA
7 are thought to activate aleurone cells, and GA
1 and GA
4 are thought to regulate embryo development. GA
2 and GA
22 are two other active gibberellins, while others like GA
12, GA
17 and GA
26 show no sign of reaction. The importance of endogenous GAs as a seed germination enhancer has also been earlier emphasized by reference [
208]. When the seeds of
D. membranaceus Munro were soaked in GA
3 solution (50 ppm) overnight, a high percent of seed germination was stimulated, with a corresponding increase in shoot length (2.70 mm) and number of sprouts (7) per explant during culture initiation [
141]. Similarly, reference [
209] discovered that 0.5-mg/L GA
3 supplemented in media promotes the germination of
D. giganteus Munro seeds under light better than BAP and Kn. In addition, GA
3 at 50 ppm was found to be the best pre-sowing treatment on
D. hamiltonii seeds, with a statistically significant improvement in seed viability [
200]. Furthermore, seed primed with 1% KNO
3 solution increased the germination of
D. strictus (Roxb.) by 80.4% at the fastest rate, and no mortality was recorded when transferred to soil [
210]. However, reference [
211] observed that osmopriming with KCl (10%) resulted in a maximum germination percentage of 83.1% when compared to KNO
3 and PEG-6000 on
D. strictus seeds. Meanwhile, reference [
212] soaked the
D. sinicus seeds in 0.5% (
v/v) potassium permanganate (KMnO
4) for 12 h and resulted in a high germination rate.
