Reduce the adverse impact of high temperature on the green garlic production for export [electronic resource]

Includes bibliographic reference

This work was carried out at a private farm in Tokh, Kalubia, Gov., Egypt during the two successive seasons of 2013/14 and 2014/15, using randomized complete block design with three replications to study the effect of pre-soaking seed cloves and foliar spray of silicon (Si), selenium (Se) concentrations and their combinations on germination, early seedlings growth, marketable and total green yield as well as chemical constituents of garlic planted under high temperature conditions of late summer (End of August). The results of this study showed that planting garlic under high temperature stress lead to drop in both rate and speed of germination, which reflected on growth and yield. However, soaking seed cloves in 4 mg/L silicon and/or 2 mg/L selenium solutions significantly increased in each of percentage, speed and coefficient velocity of germination as well as seed vigor index compared with untreated control. The soaking seed cloves in silicon at 4 mg/L. was found to produce more increase in germination index and early seedlings growth compared to selenium at 2 mg/L. The highest values of bulb characters, marketable and total green yield, as well as chemical constituents were achieved with application both Si and Se together as combination in a mixture.
