“…Use of rootstocks likely altered the leaf structure, mesophyll thickness, and the number of cells in the palisade parenchyma, the spongy parenchyma, and the intercellular spaces [4], thereby improving the photosynthetic assimilation. According to another report, under heavy metal stress conditions, pumpkin rootstock improved the chlorophyll content and rate of photosynthesis of watermelon scion [22]. Similarly, the chlorophyll contents and plant growth of brinjal cultivar "Jiza long" was substantially improved by grafting onto an eggplant rootstock "Hiranasu" under suboptimal temperature conditions [31].…”

“…Watermelon grafting onto rootstocks enhanced the nitrogen uptake efficiency and nitrogen use efficiency by 21% and 38%, respectively [30]. According to some previous studies, rootstocks enhance nutrient [14,39,40] and cytokinin supply to the scion, improve growth and dry matter accumulation, and trigger the gene expression of nitrate reductase and nitrite reductase enzymes [4,22,43]. In fruit crops, such as grapes, nitrate uptake is favored by the presence of rootstocks and the characteristics of the scion.…”

“…Grafting mini-watermelon onto rootstocks improved the total leaf area and the SPAD index [13]. Pumpkin rootstock improves the relative chlorophyll content and rate of photosynthesis of watermelon, by inducing the expression of the chlorophyll synthesis genes and reducing the expression of the chlorophyll degradation genes [4,22]. The vigorous root system of the rootstocks helps enhance water and ion uptake from the soil solution, and transport to aboveground plant parts [19].…”

“…NUE of grafted transplants is dependent on the genetic potential of the scion and the rootstock, and their interaction. Rootstocks improve the ion uptake in several plant species [4,[16][17][18][19][20][21][22]. Selection of an appropriate rootstock for a specific scion cultivar is important in order to enhance water and ion absorption, nutrient use efficiency, and plant growth and yield [23,24].…”

Nitrogen availability is the key determinant of plant growth and development. The improvement of nitrogen use efficiency (NUE) in crops is an important consideration. In fruit and vegetables, such as watermelon, rootstocks are often utilized to control soil borne diseases and improve plant performance to a range of abiotic stresses. In this study, we evaluated the efficacy of 10 wild watermelon rootstocks (ZXG-516, ZXG-941, ZXG-945, ZXG-1250, ZXG-1251, ZXG-1558, ZXG-944, ZXG-1469, ZXG-1463, and ZXG-952) to improve the plant growth and nitrogen use efficiency (NUE) of the watermelon cultivar: Zaojia 8424. Nitrogen use efficiency (NUE) is a comprehensive parameter that represents the ability of a plant to absorb nitrogen (N) and convert the supplied resources to the dry biomass. Wild watermelon rootstocks substantially improved plant growth, rate of photosynthesis, stomatal conductivity, intercellular carbon dioxide concentration, rate of transpiration, nitrogen uptake efficiency, nitrogen use efficiency, and nitrogen utilization efficiency of watermelon. NUE of watermelon grafted onto ZXG-945, ZXG-1250, and ZXG-941 was improved by up to 67%, 77%, and 168%, respectively, at optimum N supply. Similarly, at low N supply (0.2 mM), NUE of watermelon grafted onto ZXG-1558 and ZXG-516 was improved by up to 104% and 175%, respectively. In conclusion, grafting onto some wild rootstocks can improve nitrogen use efficiency of watermelon, and this improved nitrogen use efficiency could be attributed to better N uptake efficiency of wild watermelon rootstocks.

“…Grafting has been widely used for the improvement of crop quality, growth and yield; to alter varieties; to increase environment stress resistance; and to optimize cross-pollination [11][12][13][14][15]. Beyond that, grafting also has a significant impact on improving plant nutrient uptake [16][17][18].…”

Background In the previous study, we investigated the alleviation effect of grafting on potassium uptake in roots and tobacco growth inhibition under low potassium stress. However, the effect of grafting on the low potassium stress perception and coping mechanism of tobacco at the whole plant level is not clear now. In order to clearly understand the impact of grafting on potassium deficit responding mechanism in tobacco, a mutual grafting experiment has been conducted in two varieties of tobacco (‘Wufeng No.2’ and ‘Yunyan 87’) in different K supply level (5mmol L -1 and 0.5 mmol L -1 K). Results The results show that compared with the self-rooted seedlings, grafting significantly increased the potassium content of the whole plant of Yunyan 87 (97.57% and 189.74% under normal potassium and low potassium conditions, respectively), and the increase in shoots was greater. The data of whole plant K content distribution and tobacco hypocotyls net K + flux demonstrates that potassium stress makes plants more inclined to maintain K + in the shoot rather than root. In addition, when K deficiency occurs, grafting could reduce the time required for downward net K + flux in tobacco hypocotyl to decrease to stable levels. The results of net K + flux in the roots indicated that K channel proteins and transporters play different roles in two rootstocks in terms of potassium tolerance. Transcription level analysis suggested that the increased circulating efficiency of K + between the shoots and roots in tobacco constitutes one means to low potassium stress adaptation. Conclusions Grafting can activate more K + channels in tobacco ‘Yunyan 87’, this means a more active K + cycle, higher potassium content in shoot and faster response to low potassium stress signals in grafting tobacco. In addition, grafting can also change the K + absorption mode of tobacco root from being dominated by HATS to being jointly responsible by HATS and LATS, greatly improving the ability of K + transmembrane transportation on root surface under low potassium stress. These are undoubtedly the reasons why grafting tobacco performs better in coping with low potassium stress.
