“…1) weight results would be probably associated with asparagus autotoxicity which has been extensively investigated [21][22][23]. There are numerous reports of declining productivity from old asparagus plantings and extracts from asparagus tissue that had been dead for at least 8 months in the field still contained substances that retarded development of asparagus seedlings, and that the autotoxin was heat stable and water soluble [24,25]. Crowns of plants grown in plastic seedbed would be increase autotoxicity effects ( Fig.…”

Abstract:The aims of this work were to study the effect of two different plastic containers on asparagus growth and the effect of early applied 6-benzilaminepurine (BAP) on crown growth during the first two years after seed germination. Although there was not found a root restriction effect with the use of plastic containers, there were significant differences between plants grown in plastic seedbed or single pots which suggesting an unusual and unexpected asparagus autotoxicity. The results showed that crown fresh weight, total dry weight, relative growth ratio (RGR root ), root:shoot ratio and photosynthetic shoot number increased in BAP-sprayed plants over the controls without treatment as a result of a change in photosynthate partitioning towards the root system. The BAP sprays seem to be a greater effect under conditions with favor autotoxicity such as the seedbed than in single pot crown-grown.

“…Continuous mono-cropping often results in problems such as yield and quality decline , which is considered a continuous cropping obstacle (Li et al, 2013). Replanted perennial crops usually grow slowly and undergo continuous cropping obstacles (Mazzola et al, 2012;Lake et al, 1993). Soil microorganisms are extremely important components of sustainable agro-ecosystems (Lupwayi et al, 1998), and play a key role in crop production in agricultural systems (Zhao et al 2013).…”

Fusarium oxyporum f. sp. nelumbicola is a very important plant pathogen that can cause lotus Fusarium wilt and lead to vast economic loss in Jiangxi Province, china. Sequencing data of 16S ribosomal Rna genes and internal transcribed spacer regions revealed that different bacterial and fungal communities were present in soil samples from healthy or Fusarium wilt-infected lotus fields with different years of continuous cropping, indicating that the long-term continuous cropping of lotus significantly altered the soil microbial communities. Fungal diversity indexes in the healthy soil samples increased with the years of monoculture, but decreased in the Fusarium wilt-infected soil samples, whereas bacterial community diversity in all the soil samples was relatively stable. a cluster analysis revealed that consecutive cropping time was a key factor for determining fungal community structure, but not for bacterial community structure. The relative abundances of Proteobacteria, Acidobacterial, Ascomycota, and Basidiomycota phyla decreased with the years of lotus monoculture. compared with the healthy soil samples, the abundances of beneficial bacteria in the Fusarium wilt-infected soil samples significantly decreased with time. These observations indicate that soil weakness and lotus Fusarium wilt disease may be attributed to structural changes of soil microbial communities after long-term continuous cropping, and the changes include reduction of beneficial microorganisms and accumulation of fungal pathogens.

“…Asparagus decline is supposed to be caused by the contribution of both biotic (disease) (Knaflewski et al, 2008;Wong and Jeffries, 2006) and abiotic (allelopathy etc.) factors (Lake et al, 1993;Miller et al, 1991;Yong, 1984). As biotic factors, the most common phenomenon is Fusarium crown and root rot, caused by Fusarium oxysporum f. sp.…”

Influence of arbuscular mycorrhizal fungi [AMF, Glomus sp. R10 (Gr) and Gigaspora margarita (GM)] and sodium chloride (NaCl) on Fusarium root rot and antioxidative abilities in asparagus (Asparagus officinalis L., 'Welcome') plants was investigated. AMF plants accumulated higher dry weight of shoots than non-AMF plants with or without NaCl treatment during 16 weeks after AMF inoculation. Ten weeks after Fusarium oxysporum f. sp. asparagi (Foa, MAFF305556, N9-31, SUF1226, and SUF844) inoculation, the incidence and severity of Fusarium root rot were eased in AMF plants; most of the Gr plants showed lower severity than GM. In this case, a synergetic effect in disease suppression occurred in some of the AMF plants treated with NaCl. As for antioxidative ability, SOD activity of shoots and roots increased in most of the Gr plants in both NaCl-and non-treated plants 10 weeks after Foa inoculation. Gr plants had higher DPPH radical scavenging activity of shoots and roots than nonmycorrhizal plants with or without NaCl, especially 16 weeks after AMF inoculation. Ascorbic acid contents of shoots and roots increased in most of the Gr plants without NaCl treatment both 16 weeks after AMF and 10 weeks after Foa inoculation. From these findings, AMF induced a growth promotion effect and alleviation of Fusarium root rot in asparagus plants, and the synergetic effect of disease suppression could be expected by the combination use of AMF and NaCl. In addition, it supposed that changes in antioxidative ability might be associated with disease reduction in mycorrhizal asparagus plants.
