分析還表明，主要性狀的變化與種源的原產(chǎn)地氣候、地理位置重要因子有著復(fù)雜且多樣的聯(lián)系；
The provenance trails including 28 seed sources of Schima superba was used to illustrate the differences among provenances in seedling dry matter accumulation and allocation.
利用28個木荷種源的苗期測定材料，研究了不同種源的干物質(zhì)積累和分配規(guī)律。
This will help in overcoming many of the problems associated with seed provenance and assures installation of planting material that is suitable for the climatic conditions of the site.
這有助于解決與種子來源相關(guān)的問題并確保所選種植材料同基地的氣候條件相適應(yīng)。
