| Abstract | ||||
| Greenhouse experiment was conducted in El-Kassassin Res. Station, Ismailia, Egypt, during 2012/13 growing season, to determine the effect of soil water deficit at different rates of water holding capacity (W.H.C) 80, 60 and 40%, on incidence of pink root disease and yield of garlic (cv. Seds-40), as well as the plant response to the soil water deficit. Garlic plants exposed to 80% rate of W.H.C. was not significantly affected on disease incidence, seed germination (%), leaves dry weight, cell sap concentration, proline concentration and yield in infested or uninfested soils with Pyrenochaeta terrestris in comparison with the check. At 60 and 40% rates of W.H.C. noticeable increases in pink root incidence in plants inoculated with P. terrestris, but yield was decreased. Seed germination (%) and leaves dry weight were significantly reduced, whereas, cell sap and proline concentrations were significantly increased under water deficit of plants grown in uninfested soil, comparing to the check. Moreover, 40% rate of W.H.C. was highly effective on this respect comparing to the other tested rate | ||||
