Seedling Germination: Seedlings Follow Sunshine and Fresh Air

Seedling Germination: Seedlings Follow Sunshine and Fresh Air

The journey from seedling to plant requires guidance in the dark to establish which directions the roots and shoots should grow. A new study shows that, after germinating in darkness, plant seedlings sense the oxygen content of the surrounding airspace to guide further development.

Seedling production of gurguéia nut (Dypterix lacunifera Ducke) I: Seed germination and suitable substrates for seedlings

Methods of seed germination and suitable substrates for seedling growth of gurguéia nut (Dipteryx lacunifera) were studied in the present work. The following methods of seed germination i.e. I and II) Room temperature water soak for 24 and 48 hours; III, IV, V and VI) hot water soak, for 5, 10, 15 and 20 minutes, respectively; and VII) mechanical scarification, were studied. The studied substra...

Optimizing Seed Germination and Growth of Seedlings in Persian Walnut

The efficiency of conventional stratification methods for seed germination of walnut (Juglans regia L.), which uses long moist-chilling periods, is low. This experiment was conducted during winter to spring 2014 to optimize the seed germination of walnut ‘Chandler’ via changing growing media and removing seed mechanical dormancy. Fourteen treatments were tested. None of the seeds germi...

Fresh air and exercise.

When I was older and maybe looked a bit peaky or if there were any personal dilemmas in my life, my father’s answer was always “a good walk over the hill will sort you out”.
