The seeds of Toona sinensis were cultivated at (25±1)℃and the metabolic mechanism during initial germinating stages was discussed by measuring the changes of moisture content, respiratory rate, stored materials, enzymes activities and hormone contents.
The results were showed as follows:
1.The cotyledon cell of Toona sinensis seeds contains abundant black granules and lipid materials, and they degraded sharply after incubation for 18h.
2.Changes of moisture content and respiratory rate...
