“…Studying the effects of five levels of soil salinity (of saturation extract) in five cultivars of processing tomato, Souza (1990) observed decrease in the number of fruits and yield, starting from the level of 2.46 and 4.52 dS m -1 , respectively, with reduction of the average fruit weight, these effects being more pronounced at 9.60 dS m -1 . Scholberg & Locascio (1999) used waters of salinity up to 4 dS m -1 for drip irrigation of tomato and verified linear reduction in the number of fruits, total yield, and average fruit weight, while the number and production of marketable fruits were affected in a quadratic manner.…”

Industrial tomato is the most important vegetable crop of the Brazilian agribusiness. Few researches have evaluated the tolerance of this crop to saline stress. In this study, the effects of five levels of salinity of the irrigation water (1, 2, 3, 4, and 5 dS m-1) and two equivalent proportions of Na:Ca:Mg (1:1:0.5 and 7:1:0.5) were tested on yield and quality of fruits of industrial tomato, cultivar IPA 6. Seedlings were transplanted in rhizotrons and grown under plastic covering until fruit ripening. Volume of water for daily irrigations was determined by the difference between the applied and drained volume in the previous irrigation. Unitary increase of water salinity above 1 dS m-1 reduced the commercial and total yield by 11.9 and 11.0%, respectively, and increased the concentration of soluble solids and the titratable acidity of the fruits by 13.9 and 9.4%, respectively. The increase of the proportion of sodium reduced the total and marketable yield, the number of marketable fruits and pulp yield. Water of moderate salinity, with low concentration of sodium, can be used in the irrigation of the industrial tomato, without significant yield losses.

“…Planting of snap beans were done in 2-gallon (7.57 L) pots filled with un-sterilized soil along with two tablespoons of Root Naturally Endo Mycorrhizae (RNEM). The mycorrhizal inoculant contained a mixture of various AMF species (Glomus intraradices, Glomus mosseae, Glomus aggregatum, and Glomus etunicatum), which placed two inches below the soil surface (a modified method from [22,34]. Root Naturally Endo Mycorrhizae was applied only to treatments that contained AMF inoculation (i.e., IT1SC, IT2SC, IT1S1, IT2S1, IT1S2, and IT2S2).…”

Effect of Salinity Stress and Microbial Inoculations on Glomalin Production and Plant Growth Parameters of Snap Bean (Phaseolus vulgaris)

et al. 2019

Salinity is a major abiotic stress that can adversely affect plant growth, yield, other physiological parameters, and soil health. Salinity stress on biomass production of salt-sensitive crops, like snap bean (Phaseolus vulgaris), is a serious problem, and specifically in South Florida, USA, where saline soils can be found in major agricultural lands. Research studies focused on the ‘snap bean–Rhizobium–arbuscular mycorrhizal fungi (AMF)’ relationship under salinity stress are limited, and fewer studies have evaluated how this tripartite symbiosis affects glomalin production (GRSP), a glycoprotein released by AMF. A shade house experiment was conducted to elucidate the effects of three microbial inoculations (IC = inoculation control; IT1 = AMF and IT2 = AMF + Rhizobium) on three salinity treatments (SC = salinity control 0.6 dS m−1, S1 = 1.0 dS m−1, and S2 = 2.0 dS m−1) on snap bean growth and yield. Our results indicate that S2 reduced 20% bean biomass production, 11% plant height, 13% root weight, and 23% AMF root colonization. However, microbial inoculations increased 26% bean yield over different salinity treatments. Maximum salinity stress (S2) increased 6% and 18% GRSP production than S1 and SC, respectively, indicating the relative advantage of abiotic stress on AMF’s role in soil. Dual inoculation (IT2) demonstrated a beneficial role on all physiological parameters, biomass production, and GRSP synthesis compared to single inoculation (IT1) treatment with all three salinity levels.

“…Variability exists in cultivated tomato with respect to the tolerance of varieties to slight salinity of up to 2.3-2.5 dS m 21 . Above this limit, substantial linear reduction in the number of fruits, average fruit weight and total yield was reported (Maas 1986;Scholberg & Locascio 1999).…”

This paper reviews the status of the use of grafting in two solanaceous crops of global importance, tomato and eggplant, for the control of biotic and abiotic stresses. Flooding and soil-borne diseases cause severe crop losses of tomato during the hot and wet summer months in the lowland tropics. Asian Vegetable Research and Development Center (AVRDC) recommended since 2003 the use of eggplant rootstocks VI046103 (EG195) and VI045276 (EG203) for grafting tomato scions to provide a high degree of tolerance and resistance against flooding, bacterial wilt, root-knot nematodes and other soil-borne diseases. These two eggplant rootstocks and the tomato rootstock VI043614 (Hawaii 7996) are widely used in Southeast and East Asia for successful tomato production in both the tropical lowlands and highlands, providing significant economic returns to farmers. Given the rapid evolution of plant pathogens that might cause a breakdown of the limited rootstocks currently available, as well as the challenges of other abiotic stresses such as salinity and supra-optimal temperatures, it is necessary to expand the search for new rootstocks and evaluate new rootstock-scion combinations. Breeding and evaluation of appropriate rootstocks is still a matter of trial and error because desired rootstock traits, especially for abiotic stresses, are quite complex and regulated by multiple genes. Physiological and genetic markers to guide the selection process are still lacking but are essential to fast-track the identification of rootstocks with multiple benefits. This review supports an initiative to upgrade grafting technology through evaluation of a new and wider range of rootstocks sourced from the AVRDC genebank.
