Abstract

The experiment aimed at maximizing the speed growth and number of plants obtained by the mini-steck of jasmine (Jasminum sambac (L.) Aiton) cv. Emprit. Changes in benzylaminopurine (BAP), indolebutiric acid (IBA), and “rooton” concentration.were evaluated. Branchs were used as the plant material source, which consisted of axillary buds obtained after careful excision of the leaves. The following treatments were tested: solid media (soil : sand = 1 : 1) with different BAP concentrations (0.1, 3 and 5 mg/kg), IBA (0, 100, 200 and 300 ppm/kg), and “rooton” (0, 100, 200 and 300 ppm/kg) The results showed that shoots growth slowly in the media suplemented with BAP, however, IBA 200 ppm/kg media is better. Rooton with 300 ppm/kg media showed best results for rooting induction.

Abstract

In effort to get the true-to-type “Kopyor” coconut (matured coconut with broken meat particles due to abnormal formation of endosperm), the only way is inoculate the embryo in synthetic media under in vitro condition. A protocol of coconut embryo culture was established for “Kopyor” coconut grown in East Java through testing a number of media protocols and adding auxin IBA for rooting. The media protocols tested consisted of Y3 (Eeuwens) and MS (Murashige & Skoog) basal media, i.e. Protocol I (UPLB/Philippiness) as a control, Protocol II with a series of solid media Y3 (solid Y3 in germinating phase; solid Y3 in subculture I,II,III and solid Y3 in subculture IV), Protocol III with a series of solid media Y3 in germinating phase; solid Y3 in subculture I,II,III ; and liquid Y3 in subculture IV, Protocol IV with a series of solid media MS (solid MS in germinating phase; solid MS in subculture I,II,III; solid MS in subculture IV), and Protocol V with a series of liquid media MS in germinating phase; solid Y3 in subculture I,II,III; liquid Y3 in subculture IV. The growth of Kopyor coconut embryo was very fast in media Protocol II (a series of solid media Y3) and forming prefect plantlet higher than others. The alternative protocol that could give a positive result was Protocol III, this protocol showed a plantlet good rooting. Growth regulator IBA could induce primary root of kelapa kopyor plantlets. The effective concentration to stimuli lateral root of kelapa kopyor plantlet was 2 ppm IBA.

Abstract

Availability of moleculer marker to identify the important agronomic character of plant is needed to accelerate selection activity of plant. Particularly for the complex quantitatively inherited traits - like e.g. shading tolerance of soybean - the use of such a technique will speed up the process to produce adapted genotypes.The objective of this research is to identify the linkage of molecular marker RAPD with character of shading tolerance. The morphological specific characters wich is corelated to shade tolerance is the number of productive branchs. The intensity 75% of artificial shading is optimal level for doing selection of soybean genotypes. The inheritance of shading tolerance of soybean was controlled by gene with full dominant or by two genes pairs with dominant and ressesive epistasis. There was no maternal effect in the inheritance to shade tolerance. Heritability value (0.45 – 0.54) indicated that the proportion variation caused by the genetic factors was moderate. Molecular analysis by using RAPD technique showed that UBC153, ROTH 480.01, and ROTH 480.03 primer have polymorphic band that can be used for inheritance study and linkage analysis. All polymorphisms segregated independently of each ather. Interval mapping with Mapmaker/QTL indicated that the location of the three QTLs on linkage group were at marker tolerance locus of Roth 480.01-8125 , Roth 480.03-1125, and UBC 153-19125 .

Abstract

In vitro shoot explants of white ginger and red ginger are irradiated by two different techniques. The first, the tuber explants are irradiated by 2 levels of gamma rays namely 10 and 30 Gy. The second, the shoot explants are irradiated by 2 levels of gamma rays namely 7,5 and 12,5 Gy. The irradiated explants are regenerated on modified MS medium with BAP 2 ppm and NAA 0,25 ppm. The result show that the irradiated tuber explants with 10 and 30 Gy could not initiate new regenerant of ginger. On the other hand the irradiated shoot explants with 7,5 and 12,5 Gy have been able to influence the growth and development of shoot, leaf and root. It is indicated that the level of gamma rays irradiation on shoot explants influences the induced putative mutant of ginger. However, the sprouting of red ginger on 12,5 Gy is higher and faster than 7,5 Gy, and white ginger as well as control. The other morphological characters have not been able to be identified, the experiment are still in process to detect the mutagenic influences.
