Fertigation and growth regulator on coffee seedling production in tubes
Coelho, Victor Peçanha de Miranda; Rosa, Kelly Martins; Paiva, Paulo; Moreira, Édimo Fernando Alves; Carvalho, MychelleThe use of quality seedlings is important in establishing a productive coffee crop. However, the most widely used method to produce coffee seedlings is time consuming (6-12 months) and lacks new production technologies. This study aimed to assess the use of fertigation and a growth regulator in the production of coffee seedlings, in order to develop a system faster than the conventional method. For that, Topázio c...
Timing of pollen release and stigma receptivity period of Piper vicosanum: New ...
Valentin-Silva, Adriano; Coelho, Victor Peçanha de Miranda; Ventrella, Marília Contin; Vieira, Milene FariaDichogamy is a common characteristic among angiosperms, including Piper species. In this genus, the tiny flowers are morphologically similar and have an asynchronous stamen development. However, there is no information on the duration of stigma receptivity and whether it overlaps with pollen release. To better understand mechanisms of floral function in Piper vicosanum, we provide a detailed characterization of...
