Genetic TraitVariation of Zenia insignis GeographicalProvenance in Seedling Stage

  • Received Date: 2007-07-06
  • The seed ling experiments o f n ine Zenia insign is provenances from their ma jor distribution districts w ereconducted. The resu lts show ed that there ex isted extreme d ifferences in leaf w idth, leng th and area among provenances in seedling stage, w hich correlated w ith the seed size and thousand-seed w eigh.t There w ere not sign ificantdifference in seed ling heigh,t basa l diameter and biomass among provenances. Z. insignis adapts sunsh ine and w asheat-to lerance. The basa l diameter increm ent in July and August took 47. 38% ~ 51. 90% o f the annual to ta,l w hilethe he igh t increment took 62. 82% ~ 69. 06% of the annual tota.l So, the co ld-to lerance trait should be the key facto r in Z. insignis provenance selection. The individual se lection w as the key to cultivate fastgrow ing fine varieties.
