“…This result is contradictory to previous reports showing the negative effect of CCC on the growth of stems and leaves of various species (Tezuka et al, 1989;Hussain et al, 2006). However, Kirillova et al (2003) suggested that the effects of CCC could largely depend on the physiological state of the plants and the concentration of CCC applied. We are currently conducting tests to determine the specific effects of different CCC and PBZ concentrations on lily plants.…”

The present study was to test the hypothesis that the plant growth retardants chlorocholine chloride (CCC) and paclobutrazol (PBZ) could improve the carbohydrate accumulation in lily bulbs by enhancing photosynthetic capacity and changing endogenous hormones. Plants of Lilium Oriental hybrids 'Sorbonne' were treated with a foliar spray of CCC or PBZ (both at 300 mg/L) solution, at six weeks after planting (6 WAP). The morphological parameters, endogenous hormone contents (gibberellic acid (GA), abscisic acid (ABA), and indole-3-acetic acid (IAA)), and carbohydrate contents were measured from 6 to 18 WAP, at 2-week intervals. The results showed that CCC increased the biomass of leaves and stems which might produce more photoassimilates available for transportation and utilization. However, PBZ treatment suppressed vegetative growth and favored photoassimilate transportation into bulbs. A slight delay of bud and anthesis formation was observed in both treated plants. CCC and PBZ treatments substantially enhanced the sucrose contents in leaves probably due to the increase of chlorophyll contents. Treatment with CCC or PBZ decreased GA but increased IAA contents in lily bulbs which might stimulate starch accumulation and formation of new scales. Our experiment suggested that CCC or PBZ treatment is an effective method to promote carbohydrate accumulation in lily bulbs.

“…Hence our interest in the antioxidant ambiol (2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole dihydrochloride), first synthesized at the Institute of Biochemical Physics, Russian Academy of Sciences, which displays anti-stress properties and acts as a growth regulator [5,6,[8][9][10][11][12][13]. It is demonstrated that ambiol influences formation, growth, and development processes in plants [4,5,[14][15][16][17], the content of phytohormones in plant tissues, and activities of H + -ATPase in the plasmalemmata of potato tuber cells [9,[18][19][20][21].

Synthetic growth regulators capable of stimulating or inhibiting growth processes in plants in a concentration-dependent way and increasing the plant tolerance to stress conditions have long attracted the attention of researchers [1][2][3][4]. Much recent attention has been given to synthetic growth regulators with an antioxidant action, which strongly affect plant growth processes and the development of anti-stress responses [5][6][7]. Hence our interest in the antioxidant ambiol (2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole dihydrochloride), first synthesized at the Institute of Biochemical Physics, Russian Academy of Sciences, which displays anti-stress properties and acts as a growth regulator [5,6,[8][9][10][11][12][13]. It is demonstrated that ambiol influences formation, growth, and development processes in plants [4,5,[14][15][16][17], the content of phytohormones in plant tissues, and activities of H + -ATPase in the plasmalemmata of potato tuber cells [9,[18][19][20][21]. Studies of the effects of individual antioxidants, particularly ionol [22,23] and ambiol [24], on the plant organism were initiated.Genetically transformed (transgenic) plants, e.g., potato plants carrying the gene coding for antimicrobial oligopeptides, so-called defensins, is a promising model for studying the mechanism of ambiol action. It is demonstrated that defensins are capable of protecting plants from phytopathogens [9,25], which is very important for increasing resistance and yield of potato plants.This work continues our research into mechanisms underlying the action of the antioxidant ambiol in original and defensin gene-transfected plants of potato cultivar Desire [9,15,16,18,19,24]. It was found earlier that ambiol was capable of regulating growth through either stimulation or inhibition of tuber germination of original and transgenic plants depending on the concentration [9]. It was interesting to evaluate the effect of ambiol at various concentrations on the plastids in apical tuber cells of original and transgenic potato plants, as the state of plastids in many respects reflected the functional state of apical meristematic cells under experimental conditions. The goal of the work was to study ultrastructural and morphometric characteristics of plastids in the cells of the central and axial meristems of tuber apices in original and transgenic potato cultivar Desire plants under normal conditions and after treatment with ambiol. MATERIAL AND METHODS Tuber apices of original and transgenic potato ( Solanum tuberosum L.) plants of the cultivar Desire at the stage of germination after forced dormancy were the object of this study. The potato plants were transformed at the All-Russia Institute of Agricultural Biotechnology, Russian Academy of Agricultural Sciences [9]. Whole tubers of original and transgenic plants in a natural dormancy were soaked in ambiol solution for 20 h. The growth-regulating concentrations of ambiol (5 and 60 mg/l) [9] were used in the experiment. Original and transgenic potato tubers soaked ...
