“…In watermelon, potassium plays an important role in fruit quality parameters such as color, size, acidity, resistance to transport and cracking of the rind, and the 'Precious Petite' grafted onto Line BGCIA 941 plants absorbed more potassium than ungrafted 'Precious Petite'. The potassium accumulation in the present Days after transplanting study differed from that for the Zaochunghongyu watermelon cultivar grafted onto Lagenaria siceraria and Cucurbita maxima x Cucurbita moschata hybrids, which showed no difference in potassium accumulation, in relation to the graft (Huang et al 2012). From 38 DAT, 'Precious Petite' grafted onto Line BGCIA 941 absorbed more calcium than the other treatments (Figure 2d).…”

Chemical fertilizing is one of the main inputs that increase watermelon production costs. Watermelon grafting with compatible rootstocks and a vigorous root system may increase the efficiency of nutrients absorption. This study aimed at determining the accumulation of dry matter and nutrients, as well as the agronomic performance of grafted watermelon. The triploid 'Precious Petite' watermelon was used as graft and the Line BGCIA941 (Citrullus lanatus var. citroides) as rootstock. The experimental design consisted of randomized blocks, in a split-plot, with six replicates. The 'Precious Petite' grafted onto Line BGCIA941, ungrafted 'Precious Petite' and ungrafted Line BGCIA941 were evaluated in the plot, while the subplot corresponded to the sampling time (0, 10, 20, 30, 40, 50, 60 and 70 days after transplanting). 'Precious Petite' grafted onto Line BGCIA 941 accumulated more macro and micronutrients than the ungrafted plants, increasing fruit yield, flesh firmness and rind thickness, but it did not affect the soluble solids contents. The decreasing order for nutrient accumulation in the grafted plants was N > K > Ca > Mg > P > S > Fe > Mn > Zn > B > Cu, whereas for ungrafted 'Precious Petite' it corresponded to N > K > Ca > Mg > P > S > Mn > Fe > B > Zn > Cu.

“…The whole plant material (roots + shoots) was mixed together, grounded and analyzed for nutrient content (N, P, K), respectively at DAS 18, 42 and 58. The total uptake of each nutrient accumulated in the plant was calculated as the product of leaf dry matter and nutrient concentration (Martinez et al, 2005;Huang et al, 2013).…”

The study aimed to investigate the effects of commercially available AMF inoculate (Glomus sp. mixture) on the growth and the nutrient acquisition of garden pea (Pisum sativum L.) plants. Inoculated (AMF+) and non-inoculated (AMF-) pea plants were subjected to two levels of NaCl salinity (0 and 50 mM NaCl). Several times during the growing cycle, randomly selected plants were analyzed for dry matter of roots and the aboveground biomass. Plant tissue samples were analyzed for N, P and K concentration and the total uptake, specific absorption rate (SAR) and specific utilization rate (SUR) of these elements were calculated. Raised salinity drastically decreased the dry matter of roots and aboveground biomass and significantly deteriorated the specific utilization rate (SUR) of main nutrient elements in pea plants. The presence of AM fungi significantly reduced the dry matter of roots, but on the contrary significantly increased the dry matter of shoots and the overall plant dry matter. Furthermore, AM fungi inoculation significantly increased the specific absorption rate (SAR) of N, P and K under both; control and saline conditions and enhanced the specific absorption rate (SUR). As a conclusion, the inoculation of garden pea with AM fungi significantly increased the volume and improved biomass production in pea grown as greenhouses soil amendment crop (green manure).

“…Grafting can enhance nutrient uptake and/or utilization efficiency in vegetables (Rouphael et al, 2008b; Colla et al, 2010; Salehi et al, 2010; Savvas et al, 2010), thus contributing to reduce the amount of fertilizers and production costs. Enhancement of K uptake through grafting has been reported in eggplant (Leonardi and Giuffrida, 2006), melon (Qi et al, 2006), watermelon (Huang et al, 2013), mini watermelon (Rouphael et al, 2008a; Huang et al, 2013), cucumber (Zhu et al, 2008), pepper (Penella et al, 2015), and tomato (Albacete et al, 2009; Huang et al, 2013; Schwarz et al, 2013). However, the mechanisms underlying the rootstock-mediated growth improvement in response to K deprivation have not been elucidated.…”

Root-to-Shoot Hormonal Communication in Contrasting Rootstocks Suggests an Important Role for the Ethylene Precursor Aminocyclopropane-1-carboxylic Acid in Mediating Plant Growth under Low-Potassium Nutrition in Tomato

Selection and breeding of rootstocks that can tolerate low K supply may increase crop productivity in low fertility soils and reduce fertilizer application. However, the underlying physiological traits are still largely unknown. In this study, 16 contrasting recombinant inbred lines (RILs) derived from a cross between domestic and wild tomato species (Solanum lycopersicum × Solanum pimpinellifolium) have been used to analyse traits related to the rootstock-mediated induction of low (L, low shoot fresh weight) or high (H, high shoot fresh weight) vigor to a commercial F1 hybrid grown under control (6 mM, c) and low-K (1 mM, k). Based on hormonal and ionomic composition in the root xylem sap and the leaf nutritional status after long-term (7 weeks) exposure low-K supply, a model can be proposed to explain the rootstocks effects on shoot performance with the ethylene precursor aminocyclopropane-1-carboxylic acid (ACC) playing a pivotal negative role. The concentration of this hormone was higher in the low-vigor Lc and Lk rootstocks under both conditions, increased in the sensitive HcLk plants under low-K while it was reduced in the high-vigor Hk ones. Low ACC levels would promote the transport of K vs. Na in the vigorous Hk grafted plants. Along with K, Ca, and S, micronutrient uptake and transport were also activated in the tolerant Hk combinations under low-K. Additionally, an interconversion of trans-zeatin into trans-zeatin riboside would contribute to decrease ACC in the tolerant LcHk plants. The high vigor induced by the Hk plants can also be explained by an interaction of ACC with other hormones (cytokinins and salicylic, abscisic and jasmonic acids). Therefore, Hk rootstocks convert an elite tomato F1 cultivar into a (micro) nutrient-efficient phenotype, improving growth under reduced K fertilization.
