Abstract

Sunlight is one factor that plays a major role in the process of the plant physiology. Plants will go through a variety of morphological and anatomical changes in order to be able to adapt to the environment with varying light intensity. This research aims to know the anatomical structure of leaves, foliage and Nepenthes gracilis Korth. tendrils which grow in areas with different light intensity. The research was conducted from May 2014 to September 2014. The paraffin method is used inmaking preparations of transverse incision of leaves, foliage, and N. gracilis tendrils. The results of the study on the transverse incision of the leaves, foliage and tendrils growing at different light intensity indicated a difference in the thickness of the epidermis, stomata number, thickness of cortical cell layers and size of the vessel. N. gracilis that were grown in the shaded area had thinner epidermal thickness of leaf which was 3.24 ± 0,48μm than those grown in an open area which was 6.59 ± 1,35μm. The number of stomata grown in a shaded area was fewer i.e. 44 compared to that grown in the open area which was 84. The thickness of the cortical cell layers of tendrils grown in the shaded area was thinner which was 155.30 ± 2.79 μm than those grown in an open area that was 176, 49 ± 4,23μm and the size of the vessel on the leaves and tendrils grown in the shaded area was smaller than those grown in an open area.

Abstract

Stem canker is a plants disease caused by infection of Phytophtora palmivora fungi on stems, branches, and twigs of plants. This canker disease can decrease the fruits productivity of langsat (Lansium domesticum). This research was aimed to observe the stem anatomical structure of langsat plants on seedling, sapling, pole, and tree level which are infected by stem canker disease. This research have been done at May until September 2014. Paraffin method was used to make cross section sample preparation of the langsat stem. The result of this research shows that there are differences on stem anatomical structure between normal langsat plants and infected plants. The results of anatomical observation showed that the tree with stem canker at every growth level had thicker dermal tissue, thicker cortex with irregular shape, thinner phloem layer, and bigger xilem cell’s pores with no shapes change. Dermal tissue at tree level got 3,1 times thicker than any other growth level of the plants.

Abstract

Phytoplankton plays an important role in aquatic ecosystem as a primary producer. This study aims to determine the genera, abundance and horizontal distribution of phytoplankton and to measure the physical and chemical characteristics in the estuary of Kakap River. The study was carried out between December 2013 and May 2014. Phytoplankton samples were taken from five stasions that were determined based on the differences in the environmental conditions by Adaptive Cluster Sampling Method. The samples of phytoplankton were taken when the river water was in a tidal conditions by plankton net. The composition of phytoplankton found in estuary of Kakap River composed of 7 divisions, 7 classes and 42 genera. The highest phytoplankton abundance found at high tides were 42,825 ind/L and 35,769 ind/L respectively. The highest abundance phytoplankton was found from Bacillariophyceae (43,329 ind/L). Horizontal distribution of phytoplankton showed that the further away from the area of river basin, more abundance and more diverse of phytoplankton. Based on the value of Diversity Index (H’) (3.006 - 3.3489), Dominance Index (D) (0.0473 – 0.0613) and Evennes Index (E) (0.7118 – 0.8548), the estuary of Kakap River was in stable condition with high diversity. Characteristics of physial and chemical factors in the river were able to support the life of phytoplankton.
