Abstract
Abstract Setaria viridis var. minor and Setaria × pycnocoma occur sympatrically in various places in Japan, despite their different morphological and mechanical traits. Morphological and mechanical analyses were performed to determine whether the putative hybrid S. × pycnocoma possessed the morphological and mechanical characteristics of its ancestral species, S. viridis var. minor and Setaria italica . Our results indicated that S. italica had the highest panicle weight and longest culm with the lowest culm mechanical strength and S. viridis var. minor had the lightest panicle weight and shortest culm with the highest culm mechanical strength. S . × pycnocoma had a wide range of culm strengths, including mechanical properties of both ancestral species, which suggested that the intermediate mechanical characteristics of this species had been gained by repeated introgression within themselves.
摘要:小狗尾草(Setaria viridis)和小狗尾草(Setaria x pycnocoma)虽然形态和机械性状不同,但在日本各地均有分布。通过形态学和力学分析,确定了推测的杂种S. x pycnocoma是否具有其祖先种S. viridis var. minor和Setaria italica的形态学和力学特征。结果表明,意大利葡萄的穗重最高,茎长最长,茎机械强度最低;绿葡萄的穗重最轻,茎短,茎机械强度最高。年代。该品种具有广泛的茎杆强度,包括两个祖先种的力学特性,这表明该物种的中间力学特性是通过自身内部的反复渗入而获得的。
期刊介绍:
Plant Species Biology is published four times a year by The Society for the Study of Species Biology. Plant Species Biology publishes research manuscripts in the fields of population biology, pollination biology, evolutionary ecology, biosystematics, co-evolution, and any other related fields in biology. In addition to full length papers, the journal also includes short research papers as notes and comments. Invited articles may be accepted or occasion at the request of the Editorial Board. Manuscripts should contain new results of empirical and/or theoretical investigations concerning facts, processes, mechanisms or concepts of evolutionary as well as biological phenomena. Papers that are purely descriptive are not suitable for this journal. Notes & comments of the following contents will not be accepted for publication: Development of DNA markers. The journal is introducing ''Life history monographs of Japanese plant species''. The journal is dedicated to minimizing the time between submission, review and publication and to providing a high quality forum for original research in Plant Species Biology.
