“…The ratio was significantly different between the +AMF plots and −AMF plots, and the presence of +AMF plots increased the rate of emergence within a certain time frame compared to the −AMF plots ( Table 1). The effect on seedling growth was significantly different between the +AMF and −AMF plots 40 days after sowing, and the functional leaf Rwl (ratio of width/length) was further analyzed, which is related to photosynthesis and seedling growth intensity 32 . Seedlings were classified as relative strong seedlings if the leaf width was greater than the leaf length (Rwl >1), while seedlings were classified as relative weak seedlings if the leaf length was greater than the leaf width (Rwl <1).…”

“…At boll opening, all cotton plants in both inoculated and noninoculated plots showed evidence of mycorrhizal colonization, which was not surprising, as AMF occurs naturally in field soils. Cotton is an AMF-dependent crop 32 . However, current agricultural practices can reduce the diversity and abundance of AMF populations in the soil and increase the amount of time required to establish functional mycorrhiza 33 .…”

We previously reported on the strong symbiosis of AMf species (Rhizophagus irregularis CD1) with the cotton (Gossypium hirsutum L.) which is grown worldwide. in current study, it was thus investigated in farmland to determine the biological control effect of AMF on phosphorus acquisition and related gene expression regulation, plant growth and development, and a series of agronomic traits associated with yield and fiber quality in cotton. When AMF and cotton were symbiotic, the expression of the specific phosphate transporter family genes and P concentration in the cotton biomass were significantly enhanced. The photosynthesis, growth, boll number per plant and the maturity of the fiber were increased through the symbiosis between cotton and AMf. Statistical analysis showed a highly significant increase in yield for inoculated plots compared with that from the non inoculated controls, with an increase percentage of 28.54%. These findings clearly demonstrate here the benefits of AMFbased inoculation on phosphorus acquisition, growth, seed cotton yield and fiber quality in cotton. Further improvement of these beneficial inoculants on crops will help increase farmers' income all over the world both now and in the future. Cotton is an important natural fiber and economic crop that provides substantial benefits to humans and is an important raw material worldwide. While a large number of recent studies have confirmed that arbuscular mycorrhizal fungi (AMF) can improve the growth, yield, quality, and phosphorus acquisition in plants 1-5 , the effect of AMF on these economic and agronomic traits in cotton is largely unknown. Previous research evidence suggests that mycorrhiza-mediated inoculants can reduce the need for P fertilization by at least 25% (and even up to 50%) without any decrease in crop yield 6. We also investigated and reported recently as Zhang et al. on the field biological control effect on cotton Verticillium wilt of AMF application. The nutrient acquisition of crops is mainly controlled by root and soil microorganisms 7 , which play a key role in nutrient circulation and absorption and in fighting against soil pathogens 8,9. Beneficial soil microorganisms are an important part of agricultural ecosystems 7,10,11 and have been used in agriculture more frequently over the past few decades. Nevertheless, the cultivation of the target microorganism is not a simple task, given the large number of microbes, their functional diversity, and the complexity of microbial assemblages. AMF are important beneficial soil microbiota which can be cultured in the laboratory and have established close symbioses with plants over the past 455 million years 12. Arbuscular mycorrhizal fungi (AMF) colonize plant roots and can improve the adaptability of host plants, especially by offering additional phosphorus (P) 13,14 , nitrogen (N), and zinc 15 to plants. Root systems were extended, increasing the root surface that is utilized for nutrient uptake by more than 100-fold, by symbiosis with AMF 15. A large group of agricultura...

“…We believe that such an estimate (<1) might result from the difference in leaf morphology and structural features across a series of taxa. In fact, even for the same family (e.g., Rosaceae), the leaf shapes have a large variation, which does not lead to a close scaling relationship between leaf biomass and area [36]. In this case, the estimate of the scaling exponent for the pooled data of several species within the same family cannot cover different allometric patterns among different groups in the whole family (which means that the slopes on a log-log scale for different groups even for the same taxon might vary greatly), especially when the family has a large number of members.…”

Leaf dry mass per unit area (LMA) is considered to represent the photosynthetic capacity, which actually implies a hypothesis that foliar water mass (leaf fresh weight minus leaf dry weight) is proportional to leaf dry weight during leaf growth. However, relevant studies demonstrated that foliar water mass disproportionately increases with increasing leaf dry weight. Although scaling relationships of leaf dry weight vs. leaf area for many plants were investigated, few studies compared the scaling relationship based on leaf dry weight with that based on leaf fresh weight. In this study, we used the data of three families (Lauraceae, Oleaceae, and Poaceae, subfamily Bambusoideae) with five broad-leaved species for each family to examine whether using different measures for leaf biomass (i.e., dry weight and fresh weight) can result in different fitted results for the scaling relationship between leaf biomass and area. Reduced major axis regression was used to fit the log-transformed data of leaf biomass and area, and the bootstrap percentile method was used to test the significance of the difference between the estimate of the scaling exponent of leaf dry weight vs. area and that of leaf fresh weight vs. area. We found that there were five species across three families (Phoebe sheareri (Hemsl.) Gamble, Forsythia viridissima Lindl., Osmanthus fragrans Lour., Chimonobambusa sichuanensis (T.P. Yi) T.H. Wen, and Hibanobambusa tranquillans f. shiroshima H. Okamura) whose estimates of the scaling exponent of leaf dry weight to area and that of leaf fresh weight to area were not significantly different, whereas, for the remaining ten species, both estimates were significantly different. For the species in the same family whose leaf shape is narrow (i.e., a low ratio of leaf width to length) the estimates of two scaling exponents are prone to having a significant difference. There is also an allometric relationship between leaf dry weight and fresh weight, which means that foliar water mass disproportionately increases with increased leaf dry weight. In addition, the goodness of fit for the scaling relationship of leaf fresh weight vs. area is better than that for leaf dry weight vs. area, which suggests that leaf fresh mass might be more able to reflect the physiological functions of leaves associated with photosynthesis and respiration than leaf dry mass. The above conclusions are based on 15 broad-leaved species, although we believe that those conclusions may be potentially extended to other plants with broad and flat leaves.

“…However, it is not always the case as invasive species were more or similar efficient to acquire resources compared to native species under conditions of low resources [22][23][24][25][26]. Invasive plant can change the leaf traits to adapt the shade environment, such as expanding leaf area to increase light acquirement [27]. Besides, if the growth of exotic and native species is restricted by different resources, the increase in certain resources might not exacerbate the competitive effects of exotics [28,29].…”

Background: Invasive exotic species have caused significant problems, and the effects of extreme precipitation and drought, which might occur more frequently under the global climate change scenarios, on interspecific relationship between invasive and native species remain unclear. Results: We conducted a greenhouse experiment with three soil water levels (30-40%, 50-60%, and 70-80% of field capacity) and two cultivation treatments (monoculture pots, one seedling of either species and mixture pots, one seedling of each species) to investigate soil water content effects on the relationship between invasive Rhus typhina and native Cotinus coggygria. Rhus typhina had lower height but bigger crown area than C. coggygria in the monoculture treatment. Rhus typhina had higher height, bigger crown area and total biomass than C. coggygria in the mixture treatment. Drought decreased the growth parameters, total chlorophyll concentration, and leaf biomass, but did not change gas exchange and other biomass parameters in R. typhina. The growth parameters, leaf area index, biomass parameters, total chlorophyll concentration, and net photosynthetic rate of C. coggygria decreased under drought conditions. The log response ratio (lnRR), calculated as ln (total biomass of a target plant grown in monoculture/total biomass of a target plant grown in mixed culture), of R. typhina was lower than that of C. coggygria. The lnRR of R. typhina and C. coggygria decreased and increased with increase in soil water content, respectively. Conclusions: Rhus typhina has greater capacity to relatively stable growth to the drought condition than C. coggygria and has strong competition advantages in the mixture with C. coggygria, especially in the drought condition. Our study will help understand the causes of invasiveness and wide distribution of R. typhina under various moisture conditions and predict its expansion under climate change scenarios.
