Sensitivity to boron stress in growing media during the early seedlings stage could severely inhibit watermelon growth and development. The aim of this study was to test if watermelon (Citrullus lanatus cv. Mahbubi) performance can be improved under different boron concentrations (0, 46.31 and 935.11 µmol·L⁻¹ H₃BO₃) by grafting watermelon plants onto Cucurbita pepo Tiana F₁ hybrid rootstock. Shoot dry weight of grafted watermelon was significantly higher than those of non-grafted plants under boron stress conditions (0 and 935.11 µmol·L⁻¹). Boron concentration of the aerial organs of the grafted plants was higher than in the non-grafted ones when treated with 0 µmol·L⁻¹ H₃BO₃. However, with the application of boron (935.11 µmol·L⁻¹ H₃BO₃), the aerial organs of grafted plants accumulated lower boron than non-grafted ones. The Cucurbita pepo rootstock also improved the absorption of several other nutrients and leaf chlorophyll content and the F_v/F_m ratio was also increased at high boron root concentration. Higher activities of several antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD) and peroxidase (POX) in grafted watermelons were associated with a significant reduction in H₂O₂ and malondialdehyde (MDA) generation when compared with those of non-grafted plants under boron stress conditions (0 and 935.11 µmol·L⁻¹ H₃BO₃). Grafted plants reported improved growth, nutrient uptake and several other physiological parameters when compared to non-grafted watermelon plants under boron stress conditions.

苗期初期对生长介质中硼胁迫的敏感性会严重抑制西瓜的生长发育。本研究的目的是测试，如果西瓜（西瓜CV。Mahbubi）性能可以不同硼浓度下得到改善（0，46.31和935.11μmol·L ^-1 ħ ₃ BO ₃）通过接枝西瓜植物到西葫芦蒂纳˚F _1个混合砧木。在硼胁迫条件下（0和935.11 µmol·L ^-1），嫁接西瓜的苗干重明显高于未嫁接植物。）。用0 µmol·L ^-1 H ₃ BO ₃处理后，嫁接植物的气生器官中的硼浓度高于未嫁接的植物。但是，通过施用硼（935.11μmol·L ^-1 H ₃ BO ₃），嫁接植物的气生器官中硼的积累量低于未嫁接的植株。的西葫芦砧木也提高若干其他营养物和叶片叶绿素含量和吸收˚F _v / F_米在高硼根浓度下该比例也增加。与非嫁接西瓜相比，嫁接西瓜中几种抗氧化酶（例如过氧化氢酶（CAT），超氧化物歧化酶（SOD）和过氧化物酶（POX））的较高活性与H ₂ O ₂和丙二醛（MDA）的产生显着降低有关。在硼胁迫条件下（0和935.11 µmol·L ^-1 H ₃ BO ₃）嫁接植物。与硼胁迫条件下的非嫁接西瓜植物相比，嫁接植物的生长，养分吸收和其他一些生理参数有所改善。
