Abstract

The different levels of light intensity affect the anatomical thickness of monocotyledon ornamental plant leaves. The aim of this research was to determine the anatomical thickness of several monocotyledon ornamental plant leaves under different light intensities. The research used a factorial complete randomized design with two main factors, namely plant type and different light intensity, repeated three times. The first factor was the plant type, which consisted of six plant species of monocotyledon ornamental plants which were Chlorophytum laxum, Dracaena reflexa, Rhoeo discolor, Aglaonema commutatum, Cordyline fruticosa and Hymenocallis littoralis. The second factor was light intensity, which consisted of high light intensity (open areas) and low light intensity (shaded areas). The observation was carried out on preserved leaf anatomy made using the paraffin method with modification. The observation variables were the total thickness of the leaf, upper and lower epidermis, mesophyll (for undifferentiated mesophyll), and palisade and sponge (for differentiated mesophyll). Data were analyzed using analysis of variance followed by the LSD test if the treatment was significant. Correlation tests were carried out between total leaf thickness and each leaf anatomical part under conditions of high and low light intensity. The results showed that the interaction between plant types and light intensity influenced the total thickness of the leaves, upper and lower epidermis, and palisade. The plant types independently influenced the mesophyll and sponges, while the light intensity independently influenced only the mesophyll but not the sponge thickness. Hymenocallis littoralis was the only plant that showed thicker under low light intensity, with an increase in the thickness of the upper and lower epidermis. The palisade mainly influenced leaf thickness changes in the differentiated mesophyll.

Abstract

The atlas media contained submaterial structure and function of planttissue class XI equipped with leaf tissue in condition different lightsare created to help students distinguish between tissues in leaf organs.The purpose of this research is to compiling and knowing thevalidation of media atlas in learning submaterial structure and functionof plant tissue class XI. Method is descriptive quantitative. Atlas madethrough pre-production, production, and post-production. Instrumentvalidation used are questionnaire instruments and media questionnaireconsist of four aspects, namely presentation, content, language, andusage with 21 points of assessment indicators. Questionnairevalidation instrument conducted by 2 lecturers of Biology EducationFKIP Tanjungpura University and questionnaire media was carried outby five validators (3 biology teachers’ class XI and 2 lecturers ofBiology Education FKIP Tanjungpura University) with a likert scale.The results of the validation were analyzed according to Lawshe. Theinstrument validation results showed that the instrument is feasibleused and the validation results of the atlas media obtained CVI valueof 0.94. Aspects of language and usage obtain a minimum value ofLawshe, but the presentation aspect only obtained CVI 0.95 and thecontent aspect obtained CVI 0.88 so that it requires previous repairsmedia can be used in the learning process.

Abstract

Climate change causes drought in many places, including tropical areas, which affects ornamental plants both in morphology and anatomy. Codiaeum variegatum (L.) Rumph. ex A.Juss. and Excoeceria cochinchinensis Lour have low transpiration rates and allow them to be resistant to drought. This study aims to observe the morphology and anatomy of C. variaegatum and E. cochinchinensis leaves due to drought stress. The experimental design was a factorial completely randomized design (2x2) with 3 replications. The main factors are two types of plants and two conditions namely control and drought. The combination was the interaction between the two main factors. Observations included descriptions of leaf blades and edges every week for four weeks. Stomata changes, description of stomata and leaf anatomical tissue were counted and measured using a microscope connected to optilab. Observation results showed changes in the appearance of leaf blades and leaf rolling. Stomata and SD varied as well as the thickness of leaf tissue which was differentiated in both thickness and shape. The conclusion of this research was that C. variaegatum was a drought tolerant plant and E. cochinchinensis was low tolerant. Both plants can aprropriately be used to green the area with water constrain as well as ornamental plants.
