Abstract

This research aims to determine the taxonomic affinity of 7 members of Rutaceae based on morphological characters. There are 7 species observed namely Aurantifolia swingle, Citrus hystrix, and Citrus maxima, Citrus limon, Muurraya paniculate, Limonia acidissima, and Citrus paradis. We used 13 morphological characters including leaf surface, leaf tip, leaf base, leaf margin, flower color, crown shape, number of petals, rind, fruit shape, flesh of fruit’s color, rind’s color, fruit apex’s shape, and stem surface. Analysis using NTSYS showed that Aurontifolia swingle and Citrus paradisi share the most widely characters in leaf surface, leaf tip, leaf base, leaf margin, flower color, number of petals, fruit shape, rind’s color, and stem surface with a similarity coefficient is 0.69. This finding gives an insight that morphology still could be used in grouping species based on their similarity. We recommended to add more species in Rutaceae as well as increase the number of morphological characters to get a comprehensive data.

Abstract

One of the factors that support plants to grow and develop optimally is the availability of sufficient and balanced nutrients and minerals. Providing nutrients that are unbalanced or not in accordance with plant needs will cause symptoms of nutrient deficiencies or nutrient deficiencies. The aims of this research are (1) To determine the symptoms of the morphological appearance of corn plants in the nutrient deficiency treatment, (2) To determine the most dominant morphological appearance of the corn plants in the nutrient deficiency treatment. The type of research used was an experiment using a randomized block design with three replications. The treatment given is the provision of nutrient solutions: complete, -Ca, -S, -Mg, -K, -N, -P, Fe, - Micronutrients and water. The planting media used are cocopeat, roasted husks and a simple hydroponic method (nutrient solution as a planting medium). The parameters observed were plant height, number of leaves, leaf length and leaf width. The results of early indication of nutrient deficiency can be clearly observed in the color of the plant leaves. Leaf chlorosis is a symptom of nutrient deficiency in plants characterized by leaves that are initially green then changes color to yellow or pale. Changes in leaf color are caused by damage or malfunction of chlorophyll.
