Abstract

Durian (Durio zibethinus Murr.) is a tropical fruit grown in Southeast Asia and it has high nutritional and economic values and highly appreciated by consumers in Indonesia.  Unfortunately, there are several obstacles in planting durian in Indonesia, specifically in Aceh.  One of the abstacles is the scarcity of superior durian plants. Generally, plant conservations done conventionally through vegetative propagation.  However, this technique has disadvantage such as harming the initial plants.    Therefore, plant culture tissue has been used as a modern technique to develop durian plants. The objective of this research was to evaluate the effect of kinetin and 2,4 D on development of durian leaf explants through in-vitro bioassay. The research was conducted at Tissue Culture Laboratory, Faculty of Agriculture, Malikussaleh University from January to April 2019 using Completely Randomized Design (CRD) Factorial with 2 factors observed. The first factor was Kinetin (K): 0.0, 0.1 and 0.5 ppm. The second factor was auxin 2,4 D: 0.0, 0.5 and 1.0 ppm.  The results showed that the in-vitro application of kinetin affected the induction of leaf callus.  The application of 0.5 ppm of kinetin gave the best result compared to others.  The in-vitro application of 2,4 D 0.5 ppm also possessed the best result compared to others. There was no interaction beween in-vitro application of kinetin and 2,4 D on the growth of durian leaf callus at all parameters observed.

Abstract

Sweet kaffir lime (Citrus hystrix Dc), also called "Boh Kruet Mameh" is one of Aceh's local plants, which is currently very difficult to obtain. Sweet kaffir lime is not like the ordinary kaffir lime, which tastes sour. The fruit of sweet kaffir lime has a larger size than the regular kaffir lime, sweet and sour taste, aromatic and fresh, which can be consumed as a fruit table. The problem of developing the propagation technique of sweet kaffir lime plants is the seeds' condition, which are conventionally difficult to germinate and limited in number, making it difficult to get a high-quality seed. Thus, to overcome these problems, suitable solutions to plant propagation techniques should be sought. As for the right plant propagation technique is tissue culture technology or in vitro propagation technique. This research was conducted at the Plant Tissue Culture Laboratory, Faculty of Agriculture, Malikussaleh University. The research was conducted from February to April 2018. This research used a single randomized complete design (CRD) with ten replications. The treatment is a combination of the basic media, which consists of MS0 (MS media without BAP) and MS1 (MS + BAP 4 ppm). The result showed that the adduction of 4 ppm BAP in MS media influenced the in vitro sweet kaffir lime seeds' growth. Sweet kaffir lime seeds that were given 4 ppm BAP grew buds faster with more percentage of shoot growth, the number of shoots, and a number of leaves than the seeds without BAP adduction.

Abstract

The availability of nutrients in plants depends on the ability of plants to absorb nutrients from the soil. One of the processes absorbed by plants is by the presence of the transpiration process.  Good transpiration will provide enough nutrients for plants which increase the productivity and quality of mangosteen. One of the quality standards of mangosteen fruit for export quality is the free from yellow sap contamination. It can be possible that transpiration can improve the quality of mangosteen fruit by applying fertilization. In this study Ca fertilization was carried out on mangosteen seeds, where this study aims to investigate the effectiveness of Ca uptake by mangosteen plants with the level of water loss by transpiration. This research was conducted in November 2016-March 2017 at the Leuwikopo Experimental Garden, Bogor Agricultural University. Morphological observations were carried out in its Experimental Garden and the Postharvest Laboratory whileanalysis of calcium content of plant tissue was done at the Department of Agronomy and Horticulture, Bogor Agricultural University. Data obtained then were analyzed using ANOVA test. If the results were significant, Duncan Multiple Range Test (DMRT) was then tested at 0.05 probability level. The results revealed that the transpiration rate of mangosteen plants from several treatments showed a significant difference, the transpiration rate was higher, especially in fertilized plants. The size of the 12th leaf, plants treated with fertilizer have a larger size than the treatment without fertilization. Fertilizing and providing enough water can maintain the growth of the plants.

Abstract

Pamelo (Citrus maxima (Burm.) Merr) is one type of orange that is prospectively cultivated in Indonesia. Pamelo in Indonesia is very diverse, as the skin of the fruit is green to red, some are  with seed and seedless. Pamelo plants have diverse leaves, both in shape, size, lamina and thickness. The various leaf shapes between plants which show below the genetic resources of pamelo plants are numerous and varied. Information about pamelo aceh plants, especially about the character of leaves is still very limited. This information can be used to determine the characteristics of pamelo aceh so that later it will be very useful in classifying and grouping plants. The purpose of this study was to determine the character of the Pamelo Giri Matang leaf in Aceh, Indonesia. The study aims to see the level of diversity of pamelo in the village of Pante Lhong. The study was conducted in the village of Pante Lhong, Peusangan District, Bireuen,  District, Aceh, Indonesia and at the Laboratory of Agroecotechnology, Faculty of Agriculture, Universitas Malikussaleh, from September to November 2017. The sample plants used were 15, aged between 10 and 25 years. The research was conducted using descriptive method with sampling by purposive sampling method. Observations were carried out quantitatively and qualitatively based on Descriptors for Citrus (PGRI). The results showed that Pamelo Giri Matang Aceh Indonesia was an evergreen plant with an intensity of green to dark leaf color. The average leaf lamina has a length of 14.62 cm and a width of 7.04 cm with an average area of 59.74 cm2. The most commonly found leaf wings are obovate.

Abstract

Melon (Cucumis melo L.) is one of potential horticultural crop in Indonesia. Unfortunately, melon production is currently unable to meet national demand. The objective of this study was to investigate the effect of biofertilizer, varieties and interaction between the dose of biofertilizer and varieties on the growth and yield of melons. The study was conducted in January-April 2021 at Paloh Lada Village, Dewantara District and the Laboratory of Agriculture Faculty, Universitas Malikussaleh. These experiments were arranged in a Factorial Randomized Block Design (RBD) with two factors. The first factor was biofertilizer (P) consisting of 4 levels: P0 (0 ml/L), P1 (5 ml/L), P2 (10 ml/L) and P3 (15 ml/L) and the second factor was melon varieties (V): V1 (F1 Pertiwi Anvi) and V2 (F1 Action 88). There was 8 treatment combinations with 3 replications, resulted in 24 experimental units. The interaction between biofertilizers and varieties gave significant effect on the growth and yield of melon, while the interactions between bio fertilizer did not differ on all variables observed. The application of biological fertilizer 10 ml/L on V1 variety (F1 Pertiwi Anvi) is recommendable. There was an interaction between of biological fertilizers and melon varieties on the total dissolved solids (Brix %).
