“…In peanut (Arachis hypogaea), also applying methanol increased yield up to 20-30% [30] . The positive effects of methanol on crop yield has also been reported in soybean, with the best result from 25% (v/v) concentration [15] and some other crops [22,28,36] . The positive effect of moderate methanol concentration was also observed for F m and F v , which amounts of these fluorescence parameters were the lowest at 35% methanol application (Table 4), again assert negative impact of higher methanol application.…”

“…In addition, these bacteria may involve in nitrogen metabolism in plants, by releasing bacteria urea, enhancing N assimilation in methanol sprayed plants [7] . It has been shown that foliar application of methanol on some crops caused an increase of chlorophyll concentration in their leaves [27,29] , whereas Li et al [15] observed any obvious changes in chlorophyll contents of soybean leaves; however, grain yield, grain weight and pods per plant was increased significantly in methanol treated plants compared to control, with the highest effects with 25% (v/v) methanol solutions. Some studies on positive effects of methanol foliar application on plant growth and yield have declared that applying methanol on water-deficit plants has increased their chlorophyll concentrations and biomass, whereas treating well-watered crops with methanol has reduced their chlorophyll content and biomass accumulation [22,28,30,36] .…”

Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was done at Research Field of Faculty of Agriculture and Natural Resources, Islamic Azad University-Karaj Branch, Karaj, Iran, during 2008, based on a randomized complete block design with three replications. The first factor was different levels of methanol equal to 0 (control), 7, 14, 21, 28 and 35 volumetric percentage (v/v), which were used as foliar applications at three times during growth season of soybean, with 15 days intervals. The second factor was water stress conditions in two levels, based on depletion of 40 and 70% of available soil moisture. Some traits such as Grain Yield, Relative Water Content (RWC), chlorophyll fluorescence parameters and chlorophyll content were measured, one day before and after the third methanol application. Results: Chlorophyll content (Chl), GY, Electrolytes Leakage at second sampling, photochemical capacity of PSII (F v /F m ), maximum and variable fluorescence (F m and F V , respectively) were affected by water stress significantly (p<0.05). As drought severity was increased, mean values of photochemical capacity of PSII, Chl and RWC tend to decline, whereas minimum fluorescence (F 0 ) and Electrolytes Leakage were increased. Methanol foliar application influenced significantly (p<0.05) Chl, RWC, Grain Yield, and all fluorescence parameters. There was a positive, high correlation between GY with maximum fluorescence, photochemical capacity and also Chl and RWC in both samplings. Conclusion: It seems applying methanol on water stressed soybean plants can reduce harmful effects of drought and improve plant potential to cope with stress.

“…An investigation of peanut cultivation revealed that spraying a solution of 20% methanol resulted in increased performance of seeds in terms of weight of 100 seeds and protein content (Safarzade Vishkaei et al, 2007). Application of methanol solution spray at 25% concentration resulted in the maximum increase in soy production (Li et al, 1995). Zbiec et al, (2003) observed growth of between 12% and 30% in performance level of bean (Phaseolus vulgaris L.); sugar beet (Bets vulgaris L.) and canola (Brassica napus L.) compared with controls by application of methanol solution spray at 30% concentration (Zbiec et al, 2003).…”

An experiment was conducted to investigate the effect of methanol solution spray treatment on growth, biomass, and functional properties of bean plant under drought stress. The experiment was set up as a fully-randomized design with three replications. The first factor was four concentration levels of spray solution (Control, 10, 20, and 30%) and the spray was applied three times during the plant growth season at 10-day intervals. The second factor was three levels of drought stress; severe drought stress (25% field capacity), moderate drought stress (75% field capacity), and non-stress (100% field capacity). Test results showed that under 20% of methanol and conditions of non-stress there was significant growth of protein content of root and leaf in comparison with the control. Antioxidant enzyme activity was not affected by application of methanol solution spray but leaf antioxidant enzymes activity declined. Under non-stress and methanol concentrations of 10 and 20%, results showed a significant increase in all morphological properties compared with the control treatment. Under conditions of severe and moderate drought stress, level of methanol solution spray did not mitigate the negative effects of drought stress on the studied properties.

“…Culbertson et al (1991) reported that seeds of soybean genotype T31 were treated with 2.5 mM nitrosomethyl urea [N-methyl-N-nitrosourea] for 3 h. In the M 4 generation, 32 plants exhibited puberulence and smooth seed coats. Li et al (1995) reported that no changes were found in photosynthesis or chlorophyll content with 0, 25 or 50% (v/v) methanol during 1, 2 or 3 weekly applications. Xue-Bai et al (2000) while studying the mutagenic effect of 60 Co gamma irradiation on soybean observed that the M2 seedling were with one or three primary leaves and joined or wrinkled cotyledons.…”

The history of mutations with early results in soybean has been well documented in the literature available. Mutation breeding has been used in recent years as a valuable supplement to other methods of plant breeding in generating new variability and development of crop varieties with new architecture, superior biochemical constitution and suitable growth and developmental rhythms. The utility of this method is evident from the fact that in several crops induced mutants have been released as new varieties. In this paper, efforts have been made to review the literature on induced mutations in soybean. The different mutagenic agents used for inducing mutations, effects of different mutagenic agents on yield, quality contributing characters and resistance to different diseases have been described.
