Abstract

Agarwood (Aquilaria malaccensis) is an important species with high economic value and has many benefits, which led to an overexploitation in its natural habitat.  An effort to both provides sufficient seedling for agarwood cultivation and conservation is therefore much needed. This study has been carried out with a view to determine the effect of media types and BAP concentrations in two steps cultivation system on agarwood microshoot induction. This was a two stage-experiments i.e., microshoots induction and optimizing shoot development.  The research results showed that the interaction between different media type and BAP concentrations had no significant effect on agarwood microshoot induction.  Subsequent culture on MS media without any BAP addition showed that explant derived from MS medium solidified with 2.5 gr. L-1 Phytagel produced 2.36 ± 0.48 shoots/explant and 3.69 ± 1.16 leaves/explant.  In addition, explant derived from culture on MS medium supplemented with 4 µM BAP produced 2.28 ± 0.61 shoots/explant. This is for the first time the application of two steps culture system for Agarwood (Aquilaria malaccensis) has been deployed and how the habituation phenomenon is handled.

Abstract

Potato is an important food crop in both developed and developing countries and it is the fourth most important food crop after wheat, maize, and rice. Potato production in Indonesia has decreased in recent years, mainly due to the use of low quality tuber seed. The objective of this research was to determine the effect of plant materials, types of nutrients, and planting density on mini tuber formation, as well as to determine the best aeroponics conditions for mini tuber formation of Granola cultivar of potato. This research has been carried out experimentally using a Split-split Plot Design. The main plot was planting materials which consisted of plantlet and knol. The subplot was the type of nutrition media which consisted of Farran nutrition, Otazu nutrition, and AB-commercial mix. The sub-sub-plot was planting density which consisted of 50, 75, and 100 plants/m2. The research results showed that knol planted in aeroponics system on AB-commercial mix at a planting density of 75 plants/m2 resulted in the best mini-tuber production. In this study, for the first time three important factors for potato mini-tuber production have thoroughly been investigated in Indonesia. This finding will be used by Kledung Horticultural Seed Garden, Temanggung, for mass production of high-quality mini-tuber seed, which in turn will provide sufficient tuber seed for the farmer in its surrounding areas. By increasing the production of high-quality tuber seed, it is expected that it will contribute to the improvement of potato productivity and increase Indonesian potato production.

Abstract

This research has been carried out with a view to induce rooting and  plantlet formation, followed by acclimatization.  Micro shoots of sugarcane cv. PS 881 were cultured on Murashige and Skoog medium supplemented with different types and concentration of auxins for root induction. This research conducted experimentally using a split-plot design. The main plots were three types of auxins, which consisted of IAA, IBA, and NAA. The subplots were auxin concentrations with four levels, i.e. 0 μM, 5 μM, 10 μM, and 15 μM. Significantly faster root emergence time and higher number of roots observed in the Murashige and Skoog basal medium supplemented with 10 μM NAA. The best root length obtained in the Murashige and Skoog basal medium supplemented with NAA 0 μM. Plantlets derived from NAA 10 μM treatment showed the best performance during acclimation with a 100% survival rate. NAA at a concentration of 10 µM considered to be the best treatment in  plantlet formation and acclimatization of sugarcane cv. PS 881. This study showed that the use of MS medium with 10 uM NAA is able to increase the growth of PS 881 sugarcane plantlets. The results of this study can increase the availability of high quality seedlings and increase national sugar production.
