Abstract

Giberellic acid (GA3) is a natural and sintetic grower hormone for speeding up the germination process. The research objective is for knowing the soaking time effect, giberelin (GA3) concentration and the interaction of both factors toward germination and growth of the Robusta coffee seed. This research was carried out in a nursery garden of The State Polytechnic of Lampung, from June 2014 until July 2015. Research arranged by factorial used Randomized Completely Block Design (RCBD). First factor was Giberelin (GA3) concentration i.e. G0 (without GA3), G1 (Giberelin concentration 1000 mg.l-1), G2 (Giberelin concentration 1250 mg.l-1), and G3 (Giberelin concentration 1500 mg.l-1). The second factor was soaking time i.e. A1 (soaking until 12 hours), A2 (soaking until 16 hours), A3 (soaking until 20 hours), and A4 (soaking until 24 hours). The results showed the seed soaking with giberelin (GA3) could affect germinate power, germinated seed quantities, and dry weigh of shoot. There was interaction between giberelin (GA3) concentration and soaking time that could increase germinated seed quantities, leaves wide and dry weigh of shoot.Keywords: Robusta coffee seed, soaking time, giberelin (GA3)Permalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/31

Abstract

Indonesia is the fourth largest coffee producing country in the world after Brazil, Vietnam, and Colombia. This study aims to obtain an optimal rate of Trichoderma viride on coffee seed viability, to obtain the highest growth of Arabica coffee clones, and to obtain interaction between rate of Trichoderma viride and Arabica coffee clones on viability of coffee seeds. The research was conducted in Nursery Farm, State Polytechnic of Lampung from October to December 2016. This research use Factorial Randomized Block Design (RBD). The first factor was the Arabica coffee clone i.e. Sigarar Utang clone and S 795 clone.The second factor was the rate of Trichoderma viride fungi culture i.e.O0 (without Trichoderma viride fungi culture), O1 (100 g Trichoderma viride fungi culture), O2 (200 g of Trichoderma viride fungi culture), O3 (300 g of Trichoderma viride fungi culture). The variables observed included seed growth rate, germination rate, cotyledon rupture rate, hypocotyl height, hypocotyl diameter, normal sprouts, leaf area, root dry weight, and leaf dry weight. If there is a significant difference in α 0,05, then the test is continue with the LeastSignificanceDifference test (LSD). The best treatment of Trichoderma viride fungi dosage was dosage 200 g can increase seed growth rate for 12 days, germination rate 80,28%, and hypocotyl height 7,15 cm.The highest clonal treatment in the Sigarar Debt clone can increase the height of hypocotyl of 7,15 cm and the leaf area of 14.39 cm2.   Keywords: Arabica coffee seed, Trichoderma viride fungi culture, seed growth rate

Abstract

Characterization of morphophysiology and oil yield of 10 patchouli genotypes (Pogostemon cablinBenth.) aims to test the morphology and physiology character of nine genotypes Aceh patchouli and one comparative clone (Lhokseumawe), obtain high yield oil clones (weight plant and essential oil content), and obtain genetic and phenotypic variabilities that can be used as a new genotype selection indicators. The research was conducted at Experimental Field and Plant Laboratory of the State Polytechnic of Lampung in April until November 2016. This research used Randomized Block Design (RBD) with 10 treatment levels and 3 replications.The LSI test results on the physiological character of the nine genotypes and one comparative clone showed that NPL 9 genotypes superior to the variables of the angle of petiole, chlorophyll content, leaf area, specific leaf area, and leaf area index. The NPL 9 genotypes resulted higher yield and rendement yields than other genotypes tested and one comparator, that was 2,36%. The character of stem production and rendement has a genetic variant value greater than the environmental variant. For genetic variability and phenotypic variability in the variables observed relatively uniform so that can not be used as an indicator of selection.   Keywords: Aceh patchouli, leaf character, selection indicator, variability of genotype, variability of phenotype

Abstract

Gibberellin (GA3) is a natural growth hormone and synthesis used to break dormancy and accelerate germination and growth processes. The purpose of this study is to determine the effect of gibberellin concentration (GA3), soaking duration, and the interaction between gibberellin concentration (GA3) and soaking duration on the growth of australian pine tree seed. The research was conducted in State Polytechnic of Lampung from October 2015 to February 2016. This research used Factorial Randomized Block Design (RBD). The first factor is the concentration of gibberellin (GA3) namely A0 (without GA3), A1 (1000 mg.l-1 GA3), A2 (1250 mg.l-1 GA3), and A3 (1500 mg.l-1 GA3). The second factor is the soaking duration of GA3 namely B1 (soaking for 3 hours), B2 (soaking for 6 hours), and B3 (soaking for 9 hours). The result showed that GA3 at concentration 1500 mg.l-1 increased germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogenity, and vigor of australian pine tree seed. Soaking duration for 9 hours can increase germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogeneity, and australian pine tree seed vigor. The interaction between GA3 concentration at 1500 mg.l-1 and the soaking duration for 9 hours increased the germination, the percentage of germinated seeds, hypocotyl diameter, hypocotyl length, growth homogeneity, and australian pine tree seed vigor.   Keywords: Casuarina equisetifolia L., gibberelin, seed vigor, soaking durationPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/649
