Abstract

Nowadays, Aglaonema sp. becomes very famous in Indonesia. especially during the pandemic covid-19. Many people tend to stay home to stop the spreading of the virus. One of the activities that can be done during staying home is growing the plants as well as ornamental plants. Aglaonema sp. is one of the important and well-known foliage ornamental plants in Indonesia, commonly called “Sri Rezeki”. The generative or sexual reproduction of Aglaonema sp. is difficult, and it contains some endogenous pathogen. The common propagation techniques are by cutting and seed, which risky in the spreading of the pathogen. Micropropagation is an advanced technique to produce a large number of plants in a short time and pathogen-free transplant. This manuscript endeavor to include some important investigations and studies on the use of the Plant Growth Regulators (PGRs) on the Aglaonema sp. micropropagation.

Abstract

Orchids are very famous for their beautiful and long-lasting flowers and variety among the most diverse family of flowering plants in the world, comprising thousand species and hybrids and very attractive. The research aimed to determine the morphological features of two local orchids Phalaenopsis amabilis L. and Dendrobium x Superbiens and the stomatal characteristics of both orchids. Plants were the only living organisms that are able to convert light energy/sunlight into chemical energy, and stomata is an important part of plants for CO­2 to enter the leaf and H­­2O to be released during the photosynthetic reactions. The results showed that Phalenopsis amabilis L. was monopodial orchid and Dendrobium x Superbiensis a sympodial orchid. A qualitative descriptive research method used to describe and interpreted the type of stomata of Phalaenopsis amabilis L and Dendrobium sp. stomatal density were counted on adaxial and abaxial part of the leaf, and the highest stomatal density was obtained on the abaxial part of Dendrobium x Superbiensleaf 290.81 mm­-2. The type of stomata was anomocytic for two local orchids.
