“…T2:P/MA achieved the highest weight (5445 g), being inside the same statistical group to treatments T4:P/CL and T3:P/MO; however, it proved superior by 99.45% than the cucumber without rootstock (T1:PSP) (Table 1). Regarding NFPP and PFPP, a major increase was found in grafted plants versus non-grafted plants, matching the observations of other research works with grafted versus non-grafted plants of bell pepper and watermelon [22][23][24]. However, other research works have reported low yields of plants that were grafted in different rootstocks, as compared to non-grafted cucumber plants [25].…”

Cucumber is a vegetable crop of economic importance in Mexico. In 2023, fresh or frozen cucumber and pickle international sales reached USD 783M, placing Mexico in second rank among countries with the highest currency inflow in the world. This crop is mostly grown under protected environments with new production technologies, including rootstocks that are tolerant to biotic and abiotic factors that limit the yield and quality of the harvest. Therefore, the goal of this work was to assess three cucurbits as rootstocks (Cucurbita maxima, Cucurbita moschata and Citrullus lanatus), as well as studying the response of cucumber crop to the tested rootstocks. The following treatments were assessed: T1:PSP = cucumber Cv. Paraizo F1 without rootstock; T2:P/MA = cucumber grafted over Cucurbita maxima; T3:P/MO = cucumber grafted over Cucurbita moschata; T4:P/CL = cucumber grafted over Citrullus lanatus Citroides Var. The assessed variables included the number of fruits per plant (NFPP), fruit weight per plant (PFPP), average fruit weight (PPF), plant dry weight (PSP), xylem vessel area (AVX), number of xylem vessels (NVX), vascular bundle area (AHV) and number of vascular bundles (NHV) in roots (R), basal stalk (TB) and apical stalk (AT). Significant differences among treatments were found in the results for variables: NFPP, highlighting that T2:P/MA was superior by 46.15% versus T1:PSP and by 67.69% versus T3:P/MO. Regarding PFPP, T2:P/MA achieved the highest weight (5445 g), as it proved superior by 99.45% than the cucumber without rootstock (T1:PSP). Regarding PSP, T2:P/MA achieved the highest weight (196.65 g), significantly exceeding T1 by 137.5%. Regarding AVXR, T4:P/CL had the highest value (30,063 µm2). Regarding NHVR, watermelon had (T4:P/CL) 39.33% more vascular bundles than the root system of cucumber (T1:PSP). Treatments T2:P/MA and T4:P/CL had the highest values at AVXTB, while for variable NVXTB, treatments T3:P/MO and T2:P/MA were almost equal, surpassing non-grafted cucumber by 175.47%. However, T2:P/MA showed the greatest AHVTB, and T1:PSP was significantly superior to T3:P/MO, by 34.93%, for NHVTB. Furthermore, positive and significant correlations were found among PFPP, AHVR, and AVXTB, as well as among PSP, AVXTB, and AHVTB. Therefore, we may say that having a larger area of vascular vessels in the roots and a larger area of xylem vessels in the basal stalk leads to higher fruit yields per plant. In the same vein, the use of rootstocks is a sustainable alternative to increase fruit yield.

There is limited information in Colombia on the effect of rootstock compatibility on the amount and concentration of nutrients in avocado cv. Hass. This study aimed to determine the effect of rootstock/scion compatibility on fruit and leaf nutritional concentration. This experiment was developed in 9-year-old commercial avocado ‘Hass’ orchards in three locations with a moderately cold climate in Colombia (Rionegro, El Peñol, and Anserma). The scion cv. Hass was grafted on rootstocks with an Antillean origin. 15 trees were selected and marked in each orchard and location, and 25 fruits per tree and per treatment were taken at random (compatible and incompatible grafting). Subsequently, the fresh and dry weight of the skin (epicarp), the pulp (mesocarp), seed, and the seedcoat were obtained. The concentration of major and minor elements was analyzed in each tissue. There was no significant effect on the concentration of nutrients in the fruits from trees with and without compatibility between rootstock and scion. Statistical differences were observed at three locations in the concentration of nutrients in the different parts of the fruit. The nutrient with the highest concentration in the four fruit tissues was K, followed by N. The seed coat had the highest concentration of nutrients for all locations. The embryo had the lowest concentration of the major elements, such as N, K, Ca, Mg, S, and P. The order of the concentration in the fruit tissues was: K> N> Mg> P> Ca> S> Fe> B> Zn > Mn. The compatibility did not show significant differences between the leaf mineral content, nor did it affect the nutrient balances for each element at the foliar level.
