Abstract

Abstract The relocation of epiphytes contributes to biodiversity conservation. In this sense, studies that aim to promote the success of the process are necessary. Therefore, the objective of this work was to analyze the effects of initial fresh mass and fertilization on the propagation of two species of Rhipsalis, thus ensuring their success after relocation to a protected area. Therefore, fertilized and unfertilized plants of Rhipsalis puniceodiscus and Rhipsalis trigona initially with one or two cladodes were propagated in a greenhouse for 25 months. After relocation to a forest area, their survival was monitored for 16 months. Survival percentage, shoot length and root length were analyzed every four months. Fresh mass, dry mass and photosynthetic pigment were analyzed before relocating to a native forest. During the protected propagation stage, for both species, individuals presenting more branches and those that were fertilized exhibited more intense overall development. The propagation of R. puniceodiscus and R. trigona in a greenhouse with two cladodes is better than with one cladode. In general, R. puniceodiscus displayed better development under controlled conditions than R. trigona. Propagation using fertilization increased fresh mass and favors growth and survival rate of R. puniceodiscus and R. trigona. It is possible to relocate both species to a preserved area of the Atlantic Forest, but R. trigona presented more potential.

两种附生仙人掌科植物迁移到巴西圣保罗大西洋森林城市保护区的繁殖
附生植物的迁移有助于生物多样性的保护。从这个意义上说,旨在促进这一进程成功的研究是必要的。因此,本研究的目的是分析初始新鲜质量和受精对两种红尾草繁殖的影响,从而确保它们在迁移到保护区后能够成功繁殖。因此,在温室中,先用1枝或2枝的小红花和小红花的受精植株和未受精植株进行了25个月的繁殖。在迁移到森林地区后,对它们的生存进行了16个月的监测。每4个月分析成活率、茎长和根长。在迁移到原始森林之前,对新鲜质量、干质量和光合色素进行了分析。在保护繁殖阶段,两种植物均表现出分枝较多和受精个体整体发育较强的特点。两枝的温室里,桃金丝桃和三角红花的繁殖比单枝的好。总体而言,在控制条件下,青铁饼的生长发育优于三角木。施肥繁殖增加了鲜质量,有利于板栗和三角栗的生长和成活率。这两个物种都有可能迁移到大西洋森林保护区,但三角红木的可能性更大。
