    THE EFFECTS OF EARLY HARVESTING ON THE SEED VIGOUR OF THREE CORN (ZEA MAYS L.) HYBRIDS BASED ON GERMINATION CHARACTERISTICS
    (Aloki Applied Ecological Research And Forensic Inst Ltd, 2021) Konuskan, O.; Gozubenli, H.; Barutcular, C.; Hossain, A.; Islam, M. S.; El Sabagh, A.
    Time of harvesting in the case of corn is a key factor that contributes to obtain high seed vigour. In the context, the study was conducted at the Agricultural Experimental Area of Mustafa Kemal University, Turkey (36?15? N and 36?30? E), to evaluate the germination characteristics of three corn hybrids including ?Dekalp 6589 (FAO 700)?, ?Cadiz (FAO 700)? and ?Bolson (FAO 600)?. In order to use them in the present experiment, seeds of the selected corn were harvested at 5 day intervals, starting from the milking stage (seed harvesting of all corn hybrids was done 30 days after tasseling) to physiological maturity stages. Data on 1000 grain weight (1000-GW), electrical conductivity (EC), germination ratio (GR), germination index (GI), accelerated aging test index (AATI), cold test, cold test germination index (CTGI), and cold test germination time (CTGT) significantly varied among the selected hybrids in response to harvesting at different times. When harvesting was done after 30 days of tasseling the dry matter in cultivar ?Cadiz? showed the lowest, while the cultivar ?Bolson? showed the maximum dry matter. The earliest black layer in the cultivar ?Dekalp 6589? was found after 50 days while in the other two hybrids it was recorded 5 days later (55 days). The techniques of the present study related to evaluation seed vigour by estimating and evaluating germination properties may be used in future research as well as by farmers in field conditions for sustainable corn production in the changing climate.

    WHEAT (TRITICUM AESTIVUM L.) PRODUCTION UNDER DROUGHT AND HEAT STRESS - ADVERSE EFFECTS, MECHANISMS AND MITIGATION: A REVIEW
    (Corvinus Univ Budapest, 2019) El Sabagh, A.; Hossain, A.; Barutcular, C.; Islam, M. S.; Awan, S., I; Galal, A.; Iqbal, M. A.
    Heat and drought stresses are the most important abiotic factors that reduce crops productivity by affecting various physiological and biochemical processes. Thus, selecting cultivars with better drought or heat stress tolerance or breeding for stress tolerance will be helpful in enhancing crop productivity under harsh environments. This review elaborates the physiological basis of high temperature and drought stress tolerance in wheat which can be used as selection criteria in wheat breeding program. In addition, some agronomic selection criteria which are valid and useful in selecting stress tolerant wheat species and cultivars. The review also discussed the valid usage of stress tolerance indices (such as mean productivity (MP), geometric mean productivity (GMP), yield index (YI), yield stability index (YSI), relative productivity (RP%), stress susceptibility index (SSI), and the tolerance index (TOL)) to scan the genotypes against drought and heat stress. Beside these, exogenous application of stress signaling compounds, osmolytes, or certain inorganic salts play a vital role for alleviating adverse effects of abiotic stresses for sustainable wheat production. In addition, applications for soil amendments will also helpful in increasing wheat crop productivity under stressful conditions. All these strategies may be helpful to meet the food demands of the increasing population.
