An Overview of Oil Palm Cultivation via Tissue Culture Technique

During the last three decades, plant cell, tissue, and organ culture have developed rapidly and become a major biotechnology tool in agriculture, horticulture, forestry, and industry. Many problems in conventional breeding techniques were solved via tissue culture techniques. Plant tissue culture technique permits the growing plants in test tube or closed container in vitro under controlled environment. This technique is devoted to solve two problems: 1) To keep the plant cells free from microbes. 2) To grow the desired plants by providing suitable nutrient medium and other environmental conditions. In this chapter, a review around plant tissue culture techniques that have been reported on oil palm breeding programme will be discussed. It is including the laboratory techniques, advantages and disadvantages of the technique, the problems to produce good and prolific oil palm tissue culture clones and mitigation measures that have been reported to overcome the problems. As a conclusion, this chapter reviews tissue culture techniques that could be used to propagate oil palm clones.

Auxins and Cytokinins Involved in Micropropagation of Pepino Plant (Solanum muricatumAiton)

A reliable and successful micropropagation protocol was developed for pepino plant (Solanum muricatum Aiton) from nodal segment explants grown on MS medium. The best values of shoot multiplication traits were recorded from the addition of 3 mg.l-1 kinetin by producing 2.3 shoots/explant, 3.6 cm and 9.6 leaves/ explant which was significantly superior upon the addition of BA at the same levels. In case of adding 3 mg.l-1 kinetin, the best root formation attributes were achieved from the use of 0.2 mg.l-l IAA that resulted a maximum number of roots (14.33 roots/ explant). The longest root length (15.33 cm) was achieved when 0.3 mg.l-l IAA was used. A 100% rooting percentage was recorded from the all tested auxins including IAA, IBA and NAA. The gradually moved plantlets from the heterotrophic phase in the lab to the autotrophic phase in the greenhouse showed 100% success. The plantlets did not show any abnormal growth or morphological changes. It is concluded that this important plant can be easily propagated by tissue culture technique through a reliable micropropagation protocol.

PERKEMBANGAN BIBIT AREN (Arenga pinnata Merr) YANG DIKULTUR PADA MEDIA MS DAN WPM

Arenga palm (Arenga pinnata) is one species from palmae family. Economically, the palm is suitable for home industry, such as Balinese offering which use parts of young leaf, sap can be used as special local genius sweet drink from Bali, fruits are boilled that can be mixed with sugar for healthy ice. Arenga palm can be propagated aseptically using tissue culture technique. Culture media may varried between MS and WPM with or without adding hormone. Auxin can be added as 2.4-D ( 4 ppm) to induce callus. NAA and BAP with concentration 1.5 ppm respectively also added to induce multiplication of shoots or roots. Each treatment had 10 replicatations. Six weeks after cultured, callus growth observed only at WPM media that enriched with 2,4-D. The others treatment show the explant was dormant because did not show any growth while analysed anatomically under microscope.

Regeneration of Gardenia gummifera Linn.f by using cyanobacteria- A novel approach to tissue culture

Propagation of the medicinal plants by usage of different media and PGR’s is laborious, cost-effective and is the possibility of genetic variation. In the present investigation, a novel protocol was first time developed for propagation of Gardenia gummifera Linn.f. This protocol is useful in all aspects viz low cost, time and free from genetic variation. This technology is efficient as compared to normal tissue culture technique which is used for conservation from last of two decades.
