“…Additionally, ultrasound cause transient pore formation on the cell wall and membrane and in enhanced plasma-membrane permeability that facilitate mass transfer and uptake of molecules from the medium and release of intracellular products by the cells (Dong et al 2002). The ultrasound treatment at 300 W for 5 min improved the conversion frequencies of protocorm like bodies (PLBs) to shoot in the Dendrobium officinale (Wei et al 2012). In Zare et al (2014) study, the combination of ultrasound (10 s) and L-tyrosine feeding (2 mM) significantly increased the production of thebaine in comparison to individual utilisation of 2 mM L-tyrosine and ultrasound (10 s).…”

In the present study, the effects of ultrasound and plant growth regulators on in vitro callogenesis and secondary metabolites production in saffron calli were investigated. Accordingly, the saffron corms surface sterilized, sonicated and cultured on different concentrations of plant growth regulators (0.5, 1, 2 and 4 mg L-1 2,4-D or NAA in combination with 0.5 and 1 mg L-1 Kin or BAP). The percentage of callus induction, callus yield (fresh weight) and embryogenic callus formation were recorded and secondary metabolites of calli were measured by UV/VIS spectrophotometer three months after culture. The results indicated that sonication of the saffron corm explants significantly increased the in vitro callus induction and growth. So, the highest callus induction (100%) and yield (4.68 g) was achieved with sonicated explants cultured on MS medium supplemented with 2 mg L-1 1-naphthaleneacetic acid (NAA) and 0.5 mg L-1 kinetin (Kin). Somatic embryogenesis was significantly influenced by plant growth regulator regimes and the MS medium supplemented with 0.5 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D) plus 0.5 mg L-1 6-benzylaminopurine (BAP) and 0.5 mg L-1 NAA plus 0.5 mg L-1 Kin exhibited the highest percentage (75 and 72, respectively) of somatic embryogenesis. Secondary metabolite content of the callus cells was significantly different among the plant growth regulator regimes and the highest production of picrocrocin and safranal were occurred on the medium containing 0.5 mg L-1 2,4-D plus 0.5 mg L-1 BAP and 1 mg L-1 NAA plus 1 mg L-1 BAP.

“…It has been reported that 1,000 Hz SV with 100 dB intensity can induce the antioxidant activities in chrysanthemum seedlings and different organs of Dendrobium candidum (Li et al, 2008; Xiujuan et al, 2003). In addition to this, increased activities of antioxidant enzymes by ultrasound treatment was also noticed in Dendrobium officinale and suspension-cultured hazel cells (Safari et al, 2013; Wei et al, 2012). These results support the notion that SV-infected plants can neutralize ROS more efficiently than the non-SV–infected plants during disease progression.…”

“…Specifically, the number of cells were increased in the S phase due to sound waves (1,000 Hz and 100 dB), indicating that sound waves accelerated the growth of chrysanthemum. Ultrasound effectively increased the conversion frequency of Dendrobium officinale protocormlike bodies (PLBs) to shoot production in micro propagation when administered at 28,000 Hz and 300 W for 5 min (Wei et al, 2012). In addition, ultrasound was reported to cause the transient formation of callose in cotton seeds (Currier and Webster, 1964).…”

Plant growth is considered the sum of cell proliferation and subsequent elongation of the cells. The continuous proliferation and elongation of plant cells are vital to the production of new organs, which have a significant impact on overall plant growth. Accordingly, the relationship between environmental stimuli, such as temperature, light, wind, and sound waves to plant growth is of great interest in studies of plant development. Sound waves can have negative or positive effects on plant growth. In this review paper we have summarized the relationship between sound waves and plant growth response. Sound waves with specific frequencies and intensities can have positive effects on various plant biological indices including seed germination, root elongation, plant height, callus growth, cell cycling, signaling transduction systems, enzymatic and hormonal activities, and gene expression.
