The two orchids inhabit the bamboo forests or the evergreen broad-leaved forests in southwest of Japan. They closely resemble each other in morphology and ecology. However, G. nipponica blooms from April to May and disperses seeds until early June but G. pubilabiata blooms from October to November and disperses seeds until mid-December. An attempt to conserve G. nipponica and G. pubilabiata in situ was carried out through the water supply to their naturally occurring rhizomes using the superabsorbent polymer well absorbing water. The examination period was from mid-July, just after the end of the rainy season to October, the mid dry season. Some following ecological characteristics of the two orchids also were examined, the underground distribution of the rhizomes and its mycobionts and the symbiotic ability of some litter decomposing fungi in G. nipponica and the seasonal growth events in the two orchids. The decrease ratio in the rhizome number of G. nipponica and G. pubilabiata was low from 10 to 37% when supplied with water compared to that without water supply, respectively. The rhizomes of the two orchids inhabited the litter layer and the roots developed horizontally sticking to the litters. The mycobionts of G. nipponica formed small colonies spreading patchily on the soil and colonized between from the litter layer to the upper of A layer, at least 4cm in the depth. Some fungi induced germination of the seeds of G. nipponica on the agar medium containing no nutrients. The two orchids showed the similar growth stage in each season except for the fruiting. The obtained results indicate (1) the water supply after the rainy season will contribute greatly to the in situ conservation of G. nipponica and G. pubilabiata, (2) the two orchids and their mycobionts have the epiphytic life style to the litter throughout their lives, (3) the two orchids may be regulated closely by the East Asian monsoon climate, and (4) the dryness after the rainy season may be the fatal factor in the rhizome survival. Present investigation showed that G. nipponica and G. pubilabiata had the close association with the litter layer as the habitat and the litter decomposing fungi as the symbiont partners. The rhizomes and the litter were sewed together through the symbiont mycelia threads to form an ecological system. We designate such orchids as \"litter layer inhabiting plant\".","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"菌従属栄養植物のハルザキヤツシロランとアキザキヤツシロランの発生地での保存について研究した｡日本版レッド-データブックによれば, この二つのランは絶滅危惧種で, その原因として森林伐採, 土地利用の変化, 植物遷移が挙げられている｡二つのランは西南日本の竹林あるいは広葉樹林に生育し, 両種は形態的にも生態的にもよく類似している｡しかし, 前者が４月から５月にかけて開花し６月初旬までには種子を飛散させるのに対し, 後者は10月から11月にかけて開花し12月中旬までには種子を飛散させる｡ハルザキヤツシロランとアキザキヤツシロランの発生地での保全の試みを自然発生のリゾームに対して水を充分に含ませた高吸水性ポリマーを用いて給水することによって行った｡試験期間は梅雨直後から乾季の中期までであった｡また二つのランの生態的特質を, ハルザキヤツシロランではリゾームおよび共生菌の地中での分布そして落葉分解菌のランに対する共生能力について調べ, 二つのランではそれらの季節的な成長過程について記録した｡得られた結果は次の通りであった｡ハルザキヤツシロランとアキザキヤツシロランのリゾームへ給水した場合, リゾーム数の減少の割合は給水しなかった場合に比べて10％から37％低かった｡リゾームは落葉層で生育し, それらの根は落葉や落枝に付着しながら水平に広がっていた｡ハルザキヤツシロランの共生菌は地表面に小さなコロニーとなってパッチ状に分布し, 垂直的には落葉層からA層上部の少なくとも４cmの深さまで生息していた｡リゾーム周囲のキノコはランの種子発芽を養分無添加の寒天培地上で誘導した｡二つのランは花期を除けば季節ごとの生長は類似していた｡以上の結果から；(1) ハルザキヤツシロランとクロヤツシロランの発生地におけるリゾームへの給水は種の保全に大変有効である｡(2) 二つのランと共生菌は一生を通して落葉に着生した生活型を有している｡(3) 二つのランの生活は､東アジアモンスーン気候と密接に結びついている｡(4) 梅雨後の乾燥はリゾームの生存に影響する因子となっている｡本実験において, ハルザキヤツシロランとアキザキヤツシロランは落葉層に生息し, そこに生育している落葉分解菌を共生の相手として密接な関係をもっていることが明らかになった｡また, リゾームと落葉は共生菌の菌糸によって縫い合わされて一体となり, ラン, 落葉, そして落葉分解菌の三者からなる一種の生態系を作っていた｡われわれはこのような生活型を有するランに対して｢落葉層生息植物｣と呼ぶことを提案したい｡","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima
