Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity. However, many plant genetic resources, including geophytes, are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Lilium ciliatum is endemic to North East Anatolia. IUCN (International Union for the Conservation of Natural Resources) Red List Category of this species is Endangered (EN). Lilium ciliatum naturally grown in Zigana pass, Bayburt, Trabzon, Bulancak, Giresun and Gümüşhane is endangered and major threats of L. ciliatum are road construction and human disturbance related to ecotourism and recreation. It was reported that Lilium carniolicum naturally grown in Turkey is endangered although it isn’t in the IUCN Red List. Distribution areas of L. carniolicum are Trabzon, Rize, Artvin and it is also endemic to North East Anatolia. These species have high potential for use as ornamental plants with their colorful big flowers. In addition, the bulbs of these species are also used in the cosmetic industry and medicine. These are the main properties that increase the importance of L. ciliatum and L. carniolicum species. Therefore it is very important to protect the habitats of these species, ensure the continuity of their generations. The disappearance of these endemic species from our country means to disappear from the world. This review has been given in order to give some information about the endangered Lilium species of Turkey and conservation actions on these species in Turkey flora and take attention to the issue.

In this study, a pot study was carried out to reveal the effects of direct and foliar applications of humic acid to the growing medium in addition to basic fertilization on the development and plant quality characteristics of lily plants grown in peat + perlite medium. The experiment was carried out in an unheated greenhouse during the summer, in a greenhouse environment with a shade net on it. In the experiment, in addition to the control, the humic acid doses were 3.5 lt/da from soil, 7.5 lt/da from soil, 1.75 lt/da from leaf, 3.75 lt/da from leaf and soil + 3.5 lt/da from leaf + 1, It was applied 3 times as 75 lt/da. In the pot experiment established in three replications according to the randomized plots trial design, 10 lily bulbs were planted in each pot and humic acid applications were made at two-week intervals following plant emergence. In order to see the effect of the applications when the plant is harvested, the length of the flower stem (mm), the thickness of the flower stem (mm), the fresh weight of the branch (mm), the number of buds (pieces), the bud length (cm), the number of leaves (pieces), Full bloom stem (mm) and vase life (days) were examined. As the doses of humic acid increased, the vegetative weight of the lily plant increased, while the effect of the applications on the investigated properties was different. With the mineral elements, hormones and plant growth regulators in humic acid, it has the feature of promoting the increase of biomass in the plant.

Bu çalışma torf perlit ortamında yetiştirilen Zambak bitkisinin gelişimi ve bitki kalite özellikleri üzerine temel gübrelemeye ek olarak humik asitin yetiştirme ortamına direk ve yapraktan uygulamalarının etkilerini ortaya koymak için saksı koşullarında yürütülmüştür. Deneme yaz döneminde üzerine gölge tülü çekilmiş ısıtmasız sera ortamında gerçekleşmiştir. Denemede humik asit dozları kontrole ek olarak topraktan 3,5 lt/da, toprak 7,5 lt/da, yapraktan 1,75 lt/da, yapraktan 3,75 lt/da ve toprak + yapraktan 3,5lt/da + 1,75 lt/da olarak 3 kere uygulama yapılmıştır. Tesadüf parselleri deneme desenine göre üç tekerrürlü olarak kurulan saksı denemesinde her saksıda 10 adet zambak soğanı dikimi yapılmış ve bitki çıkışını takiben humik asit uygulamaları iki hafta arayla yapılmıştır. Bitki hasada geldiğinde uygulamaların etkisini görebilmek için bitkinin çiçek sapı uzunluğu (mm), çiçek sapı kalınlığı (mm), dal yaş ağırlığı (mm), kandil sayısı (adet), kandil (gonca) uzunluğu (cm), yaprak sayısı (adet), tam açmış çiçek sapı (mm) ve vazo ömrüne (gün) bakılmıştır. Humik asitin dozları arttıkça zambak bitkisinin vegetatif ağırlığı artarken uygulamaların etkisi incelenen özelliklere etkisi farklı olmuştur. Humik asit içerisindeki mineral elementler, hormonlar ve bitki büyüme düzenleyicileri ile bitkide biomasın artışını teşvik etme niteliği taşımaktadır.
