Abstract: (1514 Views)
A greenhouse experiment was conducted to examine the influence of Phelipanche aegyptiaca on vegetative growth, rate of photosynthesis, chlorophyll fluorescence and leaf chlorophyll content of 35 cucumber genotypes. High demand of assimilates by P. aegyptiaca caused significant reductions in shoot and root dry weight, leaf number, leaf area and plant height in all cucumber genotypes. Once plants were infected by P. aegyptiaca, the leaf chlorophyll content, the photosynthesis rate and the maximum quantum yield of PSII chemistry were significantly less than control, thus implying a reduction in carbon assimilation, photosynthesis efficiency and susceptibility of infected plants to photoinhibition. P. aegyptiaca traits were significantly affected by cucumber genotypes. There was no correlation between P. aegyptiaca traits with the reduction percentage of cucumber shoot dry weight. However, there were correlations between underground attachments number plant-1 (UAN) and percentage of cucumber root dry weight reduction (-0.58), total attachment number plant -1 (TAN) and the percentage of reduction of root dry weight (+0.39). In accordance with the results obtained, the genotypes were classified into 3 groups. It was demonstrated that the genotype number 22 (Khassib) behaved differently to other genotypes and, in particular, they suffered less damage from the presence of P. aegyptiaca.
