Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin â¦ space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall.
Germinating the Seeds. To germinate staghorn sumac seeds place them in a warm room away from direct sunlight. Regularly mist the soil in the pot with a spray bottle to keep it moist. After germination, remove the plastic wrap and position the pot in a sunny window so the seedlings can grow.
Iâm germinating a plug flat right now. The first seeds germinated in 7 days. At 21 days seeds are still coming up. It can take as long as 6 weeks or more for all of the seeds to come up. The minimum germination standard is 60%. Most varieties will germinate at 80+% and higher. I prechill the seeds in a refrigerator prior to shipping. Itâs best to store them in a refrigerator if there will be a delay in sowing. They should be frozen for 3-4 weeks as mentioned above before seeding.
