Also, the characteristics of the obtained seedlings were much better than the control seedlings.
Spaceflight and ground control seedlings were grown in the absence or presence of KMnO4 (to remove ethylene) for 6 days.
Natural mortality in the control seedlings was substantial in Avicennia and Rhizophora (10 and 40%, respectively).
All control seedlings in this experimental group grew towards the arm of the last light exposure (white bar; Fig. 3Bi), also confirming previous findings.
Growth towards previous light exposure of undisturbed control seedlings was reduced in the 'Dark' Group (white and yellow bars; Fig. 3Biii), and abolished in the 'Light-Dark' group.
In the absence of the fan, all control seedlings (100%) directed their growth toward the arm of the maze where the light was last presented (white bars).
Control seedlings (Light, n = 10; Light-Dark, n = 13; Dark, n = 10) were left in darkness and undisturbed during the testing day.
(B) In the 'Light' group (i), the growth response of tested seedlings was significantly different from control seedlings (Two-tailed Fisher's Exact Test, P = 0.002).
Branches on many of the infected seedlings became yellowed and discolored, while branches on the control seedlings retained their green color.
Among the tested laser doses (20, 25 and 30 J/cm25, 25 J/cm2 showed significant biostimulatory effect over un-irradiated control seedlings.
Control seedlings were treated with deionized water.
