TL;DR: Temperature and light were two main factors influencing the seed germination of Buddleja asiatica, B. asiatca and B. officinalis, and the survival rate was about 90% after transplantation.
Abstract: Seed morphological features and seed germination conditions of Buddleja asiatica, Buddleja officinalis and Buddleja macrostachya were investigated All three species have fine winged seeds and the weight of thousand-seed is 12-58 mg, but they have different morphologies The experiments revealed that temperature and light were two main factors influencing the seed germination Germination were observed within 5-10 d at 20-25℃ and germination rate reached over 75% after germination for 15 d 12–16 h·d-1 light with a light intensity 216-324 μmol·m-2·s-1 could stimulate seed germination of B asiatca, but light inhibited seed germi- nation of B officinalis There was no effect on the germination of B macrostachya The survival rate was about 90% after transplantation
TL;DR: Multivariate analysis of floral scent chemistry revealed marked dissimilarity between tetraploids and octaploids, and 4-hydroxy-4-methyl-2-pentanone and benzadehyde contributed greatly to this divergence in chemical scent profile.
