The duration of leaching required to improve germination at 30°C decreased as the temperature of leaching was raised. Water soluble inhibitors of germination were detected in leachates both from the pericarp and from the de-coated seed. Leaching for longer than 6 h failed to increase the ...
It can germinate even when the soil temperature is as low as 40°F (4.4°C) and up to 85°F (29°C); a rise in temperature higher than this can significantly reduce the germination rate. This is because too high or low temperatures can cause the seeds to become dormant, a state kno...
The optimal temperature for germination is 70°F; spinach seeds will germinate more slowly at temperatures as low as 35°F. Spinach will not germinate in soil temperatures greater than 85°F. Sow spinach seed ¼ inch deep and 1 inch apart; thin plants to 6 inches apart when seedlings ar...
If you haven’t yet gotten into preserving, dehydrating is the perfect place to start, requiring minimal equipment and no expertise. Drying spinach is as easy as laying it on the dehydrator trays and switching it on. The thin leaves will dry at a low temperature in 8-24 hours, depending ...

the pathogenic spores were evenly sprayed on the true leaf of the seedlings which were then kept in the greenhouse at a temperature of 20 °C and humidity of above 80%. The resistance and incidence of downy mildew were investigated 10 days after the inoculation. The incidence of each acces...
Spinach thrives in colder temperatures. For four weeks prior to and 3 weeks following when the frost has gone out it is suggested to direct seed. The increase in temperature and the lengthening, and heat of the days can cause fast bolting in the leaves of spinach. Certain cultivars can be...
(Fagioni et al.2009; Bagheri et al.2015) and temperature stress (Mogren et al.2015; Chitwood et al.2016; Ors and Suarez2016). Two genes involved in tolerance to osmotic stress have been identified (Weretilnyk and Hanson1988; Burnet et al.1995; Hibino et al.2002), but in general the...
Successive planting is best if you wish to harvest your leaves continuously through the growing season. The soil temperature shouldn’t be warmer than 70°F during the first few weeks for germination to occur. Protect your seedlings with a row cover or cold frame when the soil temperatures fall...
(500 °C) by following the method described by James et al.32. The pyrolyzed biochar was cooled at room temperature, grounded, sieved (0.154 mm), and stored in a sealed bag. The biochar physicochemical properties of electrical conductivity (EC)33, pH34, organic matter (OM)35, organic ...
