We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips, and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem, and rays are rather rich in secondary xylem
結果表明:氣生不定根具有以下結構特徵和發育特點: ( 1 )根為二原型,側根正對著木質部發生; ( 2 )幼根內皮層細胞具凱氏帶加厚,維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞; ( 2 )根中無髓和樹脂道; ( 4 )次生結構發生於根毛區,維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成; ( 5 )中柱鞘和栓內層細胞富含單寧類物質; ( 6 )次生韌皮部有石細胞,次生木質部射線發達。They are common in many situations, for example as gland cells and epidermal cells, and in xylem and phloem parenchyma, where they are concerned with active loading and unloading of vessels and sieve tubes

木射線單列,全由射線薄壁細胞組成;射線細胞水平壁薄,紋孔缺乏,端壁平滑。These are formed from a zone containing larger vessel elements produced by the cambium in the spring ( lighter layer ), followed by a zone containing smaller vessel elements ( darker layer ) produced during the late summer
春季,形成層活動旺盛,形成的次生木質部細胞,管徑大而壁厚,色澤較淡;夏末,形成層活動逐漸減弱,形成的次生木質部細胞,管徑小而壁薄,色澤較深。The secondary phloem parenchyma cells and secondary phloem ray parenchyma cells were the preferential sites for protein storage to the xylem parenchyma cells whereas a large amount of vegetative storage proteins was present in xylem, especially in the primary xylem and the inner secondary xylem of the extended stems
營養貯藏蛋白質優先在次生韌皮部的韌皮薄壁細胞和韌皮射線薄壁細胞中積累,在新梢伸長生長停止后,新梢基部莖的木質部中也積累了相當數量的營養貯藏蛋白質,主要分佈在初生木質部和內側次生木質部的各種生活的薄壁細胞中。R ays e ntirely p arenchymatous, u ni - serate ; h orizontal a nd t angential w alls o f r ay c ells a re smooth and thin
