The minimum temperature for germination of barley is 34 degrees to 36 degrees F (1 degrees - 2 degrees C). After the seed takes up moisture, the primary root (radicle) emerges. The radicle grows downward, providing anchorage and absorbing water and nutrients, and eventually develops lateral branches.arley can be distinguished by differences in head type and growth habits. In a six-rowed barley, three kernels are formed at each node of the head while in a two-rowed type, only a single kernel forms at each node (figure 1). Barley is also classed by its requirement for cold temperatures.
Set the seed flat in a warm, brightly lit area out of direct sun. The best temperature for successful germination is between 68 and 86 degrees F. The top of your refrigerator or above a hot water heater are good locations provided there is enough light available. Your portulaca seeds will germinate in 10 to 15 days.tep 2. Sow a single portulaca seed in the center of the soil in each cell of the flat. Don't cover the seeds with soil because they require plenty of light for germination.
