项目摘要
1. In order to clarify the anatomical nature of the anomalous vascular tissue of Helminthostachys leylanica, a comparative study was made in branched rhizomes with destroyed shoot Spices. In a portion below the shoot apex to an insertion position of a lateral branch, there are parenchymatous cells and tracheary elements which are radially arranged outside of the primary xylem. These tissue is suggested to be comparable to the secondary vascular tissue of Botrychium and be produced from meristematic cells which appear temporarily in relation to destruction of shoot apices and formation of lateral branches. This evidence supports the idea that the Ophioglossaceae is a living progymnosperm.2. The origin of angiosperm carpels was examined by comparing them to ophioglossoid fertile leaves. The two organs are similar in the three dimensional architecture, i. e. ovules and sporophores on the adaxial side of carpellary walls and trophores, respectively. Developmental anatomical evidence of ovules accumulated so far suggests that the development of ovules are equivalent to that of leaves. I proposed the Ophioglossoid model in which the angiosperm carpel was derived by pedomorphosis from a three-dimensional leafy organ like ophioglossoid fertile leaves and ovular anatropy is comparable to leaf hyponasty. In this model the fundamental architecture of the carpel had been established prior to carpel enclosure.
1. 摘要为了进一步明确白杨(Helminthostachys leylanica)异常维管组织的解剖学性质,对白杨(Helminthostachys leylanica)的分枝根茎与破坏的枝条进行了比较研究。在茎尖以下至侧枝插入位置的部分,有薄壁细胞和管状细胞,它们呈放射状排列在初生木质部的外面。这些组织被认为与Botrychium的次生维管组织相当,是由分生细胞产生的,这些细胞在茎尖的破坏和侧枝的形成中暂时出现。这一证据支持蛇舌科是活的前胚芽植物的观点。通过将被子植物心皮与蛇舌质可育叶片进行比较,探讨了被子植物心皮的起源。这两个器官在三维结构上是相似的,即胚珠和孢子囊分别位于心皮壁和滋养层的正面。迄今为止积累的胚珠发育解剖学证据表明,胚珠的发育与叶片的发育相当。我提出了蛇舌状体模型,其中被子植物心皮是由一个三维的叶状器官如蛇舌状体可育叶发育而来的,卵圆无缩形相当于叶片发育不全。在这个模型中,心堂的基本结构在心堂围合之前就已经确定了。
