Distribution of three congeneric shrub species along an aridity gradient is related to seed germination and seedling emergence.

Lai L, Tian Y, Wang Y, Zhao X, Jiang L, Baskin JM, Baskin CC, Zheng Y - AoB Plants (2015)

Bottom Line: Under the same treatments, seedling emergence percentages of C. korshinskii were higher than those of the other two species.The rank order of tolerance to drought and sand burial of the three species is C. korshinskii > C. intermedia > C. microphylla.The amount of precipitation and sand burial depth appear to be the main selective forces responsible for the geographical distribution of these species.

Effect of temperature and photon irradiance on FGP and GR (mean ± SE, n = 5) of three Caragana species. Different uppercase letters indicate significant differences at the same temperature under different light treatments, while different lowercase letters indicate significant differences under the same light treatment at different temperatures for the same species. P < 0.05.

PLV071F1: Effect of temperature and photon irradiance on FGP and GR (mean ± SE, n = 5) of three Caragana species. Different uppercase letters indicate significant differences at the same temperature under different light treatments, while different lowercase letters indicate significant differences under the same light treatment at different temperatures for the same species. P < 0.05.

Mentions: The effects of temperature, photon irradiance and their interactions were significant for FGP of all three species (Table 1). Seeds of C. korshinskii germinated well at all temperature regimes; FGPs ranged from 80.0 to 97.6. In contrast, seeds of the other two species had lower FGPs in the same treatments. Final germination percentages of C. intermedia seeds were highest at 15 : 25 °C. For C. microphylla, low temperature significantly inhibited germination, and FGP was lowest at 5 : 15 °C. Irradiance did not affect FGP in most treatments (Fig. 1).Table 1.
