The density of herbaceous crops creates a suitable environment to produce pathogens in the soil that intensify the attack of pathogens traditionally controlled by disinfectant, which are mostly prohibited and unlisted because of their toxicity. Grafting is an alternative technique to enhance abiotic stress tolerance and reduce root diseases due to soil-borne pathogens, thus enhancing crop production. This research study was conducted during the crop season of 2017 and 2018 in order to investigate the interactive effect of different grafting techniques of hybrid scion onto local rootstocks on plants survival, plant phenological growth, fruit yield and fruit quality under a controlled environment. The hybrid cucumber was also planted self-rooted. The cucumber (Cucumis sativus L.) cv. Kalaam F1, Syngenta was grafted onto four local cucurbitaceous rootstocks; ridge gourd (Luffa operculate Cogn.), bitter gourd (Momordica charantia L.), pumpkin (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria (Molina) Standl.) using splice grafting, tongue approach, single cotyledon and hole insertion grafting techniques and self-rooted hybrid cucumber under greenhouse conditions. The experimental results indicated that all local cucurbitaceous rootstocks showed a high compatibility with hybrid cucumber scion in the splice grafting method compared to other grafting and non-grafted methods. Lagenaria siceraria rootstocks were found highly compatible with cucumber cv Kalaam scion which gave significantly maximum plant survival rates (95%) due to high sap contents, high SPAD value, better vegetative growth and maximum fruit yield when compared with other rootstocks by employing the splice grafting method followed by tongue approach, single cotyledon and hole insertion grafting while the fruit quality of all rootstocks was observed to be similar. The non-grafted cucumber cv. Kalaam F1 showed significant results of plant vegetative growth, fruit development and fruit quality and encountered grafting methods while the lowest result were associated with the hole insertion grafting method in all scion/rootstock combinations. The grafted plants have no significant effect on cucumber fruit dry matter and fruit quality while the fruit mineral compositions (N, P, K, Ca and Mg) were higher among grafted and non-grafted plant fruits. The results indicate that grafting hybrid cucumber onto four local cucurbitaceous rootstocks influenced growth, yield and fruit quality. Grafting can be alternative and control measure for soil-borne disease and to enhance cucumber production.

Experiment was conducted during spring season 2017 in the experimental station of the Department of Horticulture and Landscape, College of Agriculture Diyala University, Iraq. In order to understand some of the effects and adaptations of the vegetative growth of the cucumber plant affected by water stress and the experiments were arranged in a Split-Split Plot Design in R.C.B.D. and with three replicates. The experiment factors were as follows: the genotypes of cucumbers, namely Demmy (V1) and Ghazeer (V2) and Wesam (V3), and second: two levels of irrigation are Complete irrigation 100% (I1) of field capacity and 50% of complete irrigation (I2). Third, spray glutathione in three concentrations (0, 50, 100) mg L-1 and its symbol (G0, G1, G2). The results of the study showed the superiority of the genotype plants in the number of leaves and leafy area (91.72 leaves plan-1 and 213.9 dcm2 plants-1) respectively. whereas the irrigated plants exceeded the level 100% significantly for all studied traits compared with the level of irrigation 50%. Also, the glutathione spray levels exceeded 50 and 100 mg L-1 (without significant difference between them) by all the characteristics compared to the comparison treatment (G0). The results of the triple interference between the genotypes, irrigation levels, and levels of glutathione spraying showed significant differences in the vegetative growth of cucumber plants, Since the treatment of interference V3I1G2 was superior to the number of branches (5, 766 branches plant-1), the total paper area (239.0 dcm 2 plants-1) and the concentration of chlorophyll (45.72 spad), While treatment V3I1G1 was superior to the number of leaves (99.66 leaves per plant-1) and dry matter percentage in the vegetative total(16.00%), and treatment V2I1G2 to excellence in plant length (148.6 cm).

The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line (GBS-1) and monoecious lines (Pusa Uday and Punjab Naveen). The F1 and F2 population along with parental lines were evaluated to study the inheritance of this trait. All F1 hybrids showed gynoecious sex in both crosses and in the F2 generation, the observed distribution of plant phenotypes fitted the expected mendelian ratio of 3 (gynocious plant) : 1 (monoecious plant). The segregation of plant sex types suggested monogenic dominant control of gynoecious sex form in cucumber using genotype GBS-1.

Gibberellic acid (GA3) promoted maleness and 2-Chloroethyl phosphonic acid (ethephon) promoted femaleness in cucumber (Cucumis sativus L.) cv Regal 446 seedlings when treated with water, ethephon (250 or 350 ppm) or GA3 (1000 or 2000 ppm) at the l-, 2-, or 3-leaf stage. Seedlings treated with ethephon at all stages produced more female flowers than those with water or GA3 treatments. GA3-treated seedlings produced significantly more male flowers than water treatments, at all developmental stages. The differential response of cucumber seedlings treated at different stages indicated the importance of timing growth regulator applications.
