Abstract

Good seedlings  have good genetic quality and physical appearance such high, diameter, age, fresh leaves, free from pests and diseases. One way to get good quality seedling  throughs fertilizing. Research aims to know response of Jabon seedling growth which  is  given organic  leaf fertilizer. Research is done in the greenhouse by using  complete random design (RAL). Treatment which is given on jabon seedlings was granting organic leaf fertilizer, namely: fertilizer X, super-O, Saputra, and Agrobost. As control, jabon seedlings not given organic leaf fertilizer. The observed variables are the seedlings high, stem diameter, wet weight of shoots and roots, shoots and root dry weight ratio tops, roots, and root length. The results showed from 9 variables observed there are 7 variables that influence on   growth of the  jabon seedling, such as: high, diameter, heavy wet shoots and root dry weight, shoot and  roots. The granting of organic  leaf fertilizer Saputra gives a better growth than other treatments in terms of high growth that is 21.38 cm (nearly 15.34%), diameter is 3.59 mm (increase  36.59%), wet weight of shoots weighing nearly 18.78 g (increase  26.90%), heavy wet roots weighing is 7.74 g (increase 68.82%), dry weight of shoots is 3.13 g (nearly 93.17%) root dry weight, weighing  1.91 g (increase 117.16%). Seedling control and seedling treatment had NPA between 1.54-2.23. Seedlings jabon on all treatments have a long the same root, but it has a number of different roots. Jabon seedlings on all the treatments have a long the same root, but it has a number of different roots. The seeds are sprayed with organic leaf fertilizers have quality index value of  seedings > 0.09, meaning seed jabon can survive if moved to the field.

Abstract

The availability of minimal seed requires alternative reproduction system of paulownia. In vitro culture is used as one of the solutions in the reproduction of paulownia. In in vitro cultural contamination is the main problem in the initiation phase. This research studies about the influence of sterilization treatment to the percentage of contamination, browning, and induction of paulownia bud. Sterilization techniques give the same effect against the percentage of contamination, browning, and induction of paulownia bud. The sterilization technique used in the study consisted of four treatment such as A (fungicide 0.2 g/L, bactericidal 0.2 g/L, NaOCl 20%, 15%, 10%), B (fungicide 2 g/L, bactericidal 2 g/L, NaOCl 15%, 10%, 5%), C (fungicide 0.2 g/L, bactericidal 0.2 g/L, detergent 20%, 15%, 10%), dan D (fungicide 2 g/L, bactericidal 2 g/L. Contamination that happened 93.96 % caused by bacteria and 11.5 % by fungi. Eksplan that is free from contamination and browning show the development of the aksilar. There is the development of a callus on some eksplan because the rates of hormone endogenous which is quite high. It strengthened by 100% the formation of callus on the stage multiplication by the addition of regulator substance growing auksin in small quantities.

Abstract

Counting the number of chromosomes can be conducted by analysis of chromosomes with chromosome staining. The purpose of this research is to find the right method for staining chromosomes of teak, time of the mitotic phase of teak, and the duration of the mitotic phase of teak. Overall, to get good results, chromosomal analysis is done through four stages in the sequence was (1) the early phase of treatment, (2) stage of fixation, (3) stages of maceration and (4) stage of coloration. In this study, there were seven methods of making preparations applied to the root tip mitosis, chromosomes are stained onion root (method A), modification of maceration (method B), modification without fixation and maceration (method C), modifications time to cut teak root (D method), modification of maceration without fixation (method E), the modification of pre-treatment without fixation and maceration (M method), and storage of the root tip before pre-treatments (method G). Chromosome staining onion roots used as a basic for the staining method is easy to get the correct teak’s chromosomes. From this study, analysis of teak’s chromosome is known that D chromosome staining method is appropriate because the methods and stages of mitotic chromosomes can be seen, but the number of chromosomes can not be calculated because the size of chromosomes were very small. the best time to cut the teak root at 9:00 to 10:00 am, and the duration of the mitotic phase of teak is ± 1 hour.Key words : chromosome, chromosome staining method, mitotic, Tectona grandis

Abstract

Ectomycorrhizal fungi usually infect the young lateral roots. Root stimulant can induce the growth of new lateral roots after application of root pruning. This research is aimed at determining the exact amount of root stimulant concentration that suffices the condition of increased root colonization of gnetum seedling by mycorrhizal fungi. The research were tested in a greenhouse in a completely randomized design for 8 months. Four levels of root stimulant concentation was used, i.e. 0.00%, 1.00%, 1.25% and 1.67%. All treatments were treated with root pruning and ectomycorrhizal fungi (Scleroderma spp.) inoculation. Growth parameters observed were the number of new roots, the percentage of ectomycorrhizal colonization, diameter, height, shoot wet biomass, shoot dry biomass, root wet biomass, and root dry biomass. The results showed that all the roots of Gnetum seedlings infected by Scleroderma spp. Root stimulant had significant effects on increasing the growth of new roots. Root stimulant with concentration 1.67% gave the best growth response on all parameters except root dry biomass. The number of new roots was 35.50, the percentage of ectomycorrhizal colonization 58.47%, diameter 3.57 mm, height 48.21 cm, shoot wet biomass 8.57 g, shoot dry biomass 3.56 g, and root wet biomass 5.81 g.Key words: Gnetum gnemon, mycorrhizal colonization, plant growth, root stimulant, Scleroderma

Abstract

Leda (Eucalyptus deglupta) is one of fast growing species that prospecting for revegetation in post mined area. Leda is able to grow in poorly soil nutrient. The aim of this research is to analyze the effectiveness of AMF and P fertilizer on growth and P uptake of leda seedling. This research was conducted in split plot in Completely Randomize Design (CRD). The application AMF as a main plot consisted of 5 levels, namely M0 (control), M1(AMF from rubber plantation), M2 (AMF from primary forest), M3 (AMF from oil palm plantation), and M4 (AMF from natural rubber). The rock phosphate as subplot, consisted of three levels, such as 0 g P (P0), 2 g P (P1), and 5 g P (P2). The result showed that interaction between AMF from rubber plantation and 2 g of rock phosphate significantly gave the best effect for height and diameter of Leda while interaction between AMF-primary forest (M2) and P1 (2 g of rock phosphate) reach the best of the total dry weight. Both AMF from primary forest and oil palm plantation that combined with 2 g of rock phosphate give the best effect but was not significantly different for P uptake and P uptake efficiency.Key words: amf, growth, miychorrhiza, leda, p uptake, p efficiency
