摘要

研究了采前喷施硝酸钙溶液对甜瓜品质的影响。处理包括五种溶液的组合，Ca(NO3)2 (0.0;1.3;2.6;5.2和10.5 g/L)和两种采后储存环境[(24.0±1.5°C和6.4±0.8 mbar的蒸汽压差(VPD)， 10.0±0.5°C和3.0±0.5 mbar(VPD)]。当Ca (NO3)2浓度为1.3和2.6 g/L时，果实在24˚C条件下贮藏11 d时水分损失量最低。结果表明，在24°C和10°C条件下，Ca(NO3)2浓度分别为2.6和5.2 g/L时，果实硬度更高。总可溶性固形物(TSS)在不同处理和不同贮藏环境下无显著差异(P < 0.05)。结果表明，随着Ca(NO3)2浓度的增加，果实表皮斑点增多。

Effect of preharvest foliar sprays of calcium nitrate on melon fruit quality

The aim of this work was to study the effect of preharvestfoliar spraying with calcium nitrate solutions on the fruitmelon quality. Treatments included a combination of five solutionswith Ca(NO3)2 (0.0; 1.3; 2.6; 5.2 and 10.5 g/L) and two postharveststorage environments [(24.0 ± 1.5 °C and 6.4 ± 0,8 mbar ofvapor pressure deficit (VPD), and 10.0 ± 0.5 °C and 3.0 ± 0.5 mbar(VPD)]. Fruits stored at 24 ˚C for 11 days had the lowest water losswith treatments 1.3 and 2.6 g/L Ca (NO3)2. It was observed thatat both 24 °C and 10 °C, fruits that had a greater firmness at the2.6 and 5.2 g/L of Ca(NO3)2 treatments, respectively. No differences(P>0.05) were observed in total soluble solids (TSS) between treatmentsand storage environments. However, spotting of the epidermisof the fruits increased as the Ca(NO3)2 concentration also increased.

期刊介绍： Phyton-International Journal of Experimental Botany is an international journal that publishes on the broadest aspects of plant biology and ecology. The journal welcomes the original and exciting submissions that provide new and fundamental insights into the origins, development, and function of plants from the molecular to the whole organism and its interactions within the biotic and abiotic environment. Phyton-International Journal of Experimental Botany publishes outstanding research in the plant and ecology sciences, especially in the areas of plant physiology and biochemistry, plant metabolism, plant ecology and evolution, as well as those making use of synthetic, modeling, bioinformatics, and -omics tools. Manuscripts submitted to this journal must not be under simultaneous consideration or have been published elsewhere, either in part or in whole.
