Abstract: Salinity is one of the abiotic stresses that can limit cucumber seedling production. It has detrimental effects on the growth and development of the seedlings including reverse osmosis, stunted growth and wilting. Research on the effects of proline and glucose on salt stressed plants has been done independently. This research therefore focused on the investigation of the effects of combining proline and glucose to mitigate saline stress in the early growth and development of cucumber seedlings. It therefore analysed and reported on the effects of exogenous application of proline and glucose on saline stressed cucumber seedlings. The variety used was Pointsett from Avanos Seeds Company. The cucumber seedlings were subjected to salinity stress of 2.5dS/m. Treatments were replicated three (3) times in a Completely Randomized Design (CRD). The treatments were: 0mM+0mmol/l; 10mM+50mmol/l; 20mM+50mmol/l and 30mM+50mmol/l. Data collected was subjected to one-way analysis of variance (ANOVA) and significance between means were determined using the least significant difference (LSD) test at P = 0.05% level. Results indicated linear increase in shoot diameter, shoot length and root length, root to shoot ratio, fresh weight and dry weight of seedlings, leaf length and leaf width. The results were presented in the form of clustered column bars, line graphs with trend lines showing linear equations and R2 values, as well as treatment means tables which were indicating LSD values for the observed parameters. The conclusion made was that as the levels of combined proline and glucose increase, even at the lowest level, so do the observed parameters, indicating the positive impact of treatment on the growth and development of saline stressed cucumber seedlings. However, as the treatment concentrations used in this study did not reach an optimum level of combined proline and glucose to use, further research is required to unravel the optimum treatment level which can be recommended to cucumber producers.
