Abstract The chemical properties, mineral contents, fatty acid and tocopherol contents of seed and seed oils of some citrus genus provided from several locations in Turkey and Saudi Arabia were determined. While Ca contents of seeds were between 5018 mg/kg (Kütdiken lemon) and 7619 mg/kg (kinnow mandarin), K contents of seeds varied between 7007 mg/kg (Orlando orange) and 10334 mg/kg (kinnow mandarin). Glucose and fructose contents of citrus seed samples varied between 3.75 g/kg and 5.75 g/kg, and 4.09 g/kg and 6.03 g/kg. Palmitic, oleic and linoleic acids were established as dominant fatty acids. Palmitic, oleic and linoleic acid contents of citrus seed oils varied between 19.6% (Kütdiken lemon) and 26.2% (pineapple orange), 21.3% (kinnow mandarin) and 31.4% (Kütdiken lemon) and 32.3% (Kütdiken lemon) and 43.7% (kinnow mandarin), respectively. The total amount of tocopherols of Turkish citrus oil varied between 0.5 mg/100 g (Fremont mandarin) and 18.8 mg/100 g (bitter orange).

Citrus (Citrus nobilis L.) Propagation Through Culture In Vitro Using Seed From Infected Plants Of Citrus Vein Phloem Degeneration (CVPD) Disease. The sample was taken in Belancan Village, Kintamani District, Bangli Regency, and invitro culture was conducted in UPT. Genetics Resource and Molecular Biology Laboratory in February to June 2018. This research purposes were to get the new citrus plant from citrus seed infected of CVPD disease explants with culture in vitro and found the presence of the bacterium Liberobacter asiaticus in results of citrus plants culture in vitro. The sampling method is using plants appearance. Obtained sample 1 is a plant that shows severe symptoms of CVPD disease and sample 2 plants that show no symptoms of CVPD disease. Seed Sample is cultured with MS0 medium for 8 WAP then proceed to acclimatization. The results of this research showed that the seed explants from both samples were able to grow well and did not have the characteristic of CVPD disease, but explant seed sample 2 in vitro culture result showed that the bacterial DNA bacterium Liberobacter asiaticus pathogen CVPD disease does exist in length 1160bp, so it cannot be expected to produce CVPD-free crops.

The recalcitrant seeds need a high moisture level during in storage to prevent loss its viability. The storage at a high moisture level is a favorable condition for fungi growth and on the other hand, a low seeds moisture level will loss the seeds viability. The citrus seeds as one of recalcitrant seeds need a special condition in storage. The storage of citrus seeds by using kencur (Kaempferia galangal L.) extract can protect the seeds against fungi during storage and preserve its viability. The purpose of this research was to determine the best concentration of K. galanga extract which protects the citrus seeds against fungi as long as period storage, the kind of fungi and its percentage of infection, and the citrus seeds viability. This research was carried out in September until November in 2004 at Plant Pest and Disease Laboratory and Greenhouse of Agricultural Faculty of Sebelas Maret University. The citrus seed used was Keprok variety from Ponorogo. The research design was a Randomized Completely Block Design (RCBD), with the treatments: (1) included the seeds without being stored and without being given by K. galanga extract, (2) the seeds were stored for 2 weeks with 100%, 75%, and 50% K. galanga extract, (3) the seeds were stored for 4 weeks with 100%, 75%, and 50% K. galanga extract, (4) the seeds were stored for 6 weeks with 100%, 75%, and 50% K. galanga extract, and (5) the seeds were stored for 8 weeks with 100%, 75%, and 50% K. galanga extract. Data were analyzed by using F test with 5% and 1% significance levels. If there were real differences, it was continued to be tested by using a Duncan multiple range test with 5% significance level. The results of this research showed that K. galanga extract by 50% was the best concentration that protected the citrus seeds against fungi for 2 weeks of storage. The storage of citrus seeds with K. galanga extract more than 2 weeks decreased seeds viability. The dominant kinds of fungi that attack citrus seeds in the storage were Aspergillus spp. and Penicillium spp., obtained by using a blotter test.

Germination And Growth

Seeds are mature ovules. One or more of the ovaries formed in the legume, but never more than one seed formed in the ovaries of monocots. Each ripe seed always consists of at least two parts, namely: (1) Embryo, (2) Seed coat (Seed coat or testa). Embryo is formed or derived from fertilized eggs (zygote) by undergoing cell division in the embryo sac. Seed coat is formed from the integument (one or more) of the ovules. In legumes generally there are two layers of seed coat. Every very young and growing seed always consists of three parts: (1) Embryo, (2) seed coat, (3) Endosperm. Endosperm is a storage food storage network which is absorbed by the embryo before or during seed germination and is always present in very young seeds. Polyembryonics is the presence of more than one embryo in one seed, but these embryos do not always mature or mature, remain undeveloped or degenerate. The purpose of this research is to study the germination of one seed that has more than one embryo and to determine the growth of seedlings from polyembryonic seeds. The results showed that the highest plant growth (plant height, number of leaves, fresh weight and dry weight of orange seeds) was found in orange seeds that had 1 embryo compared to orange seeds which had 2 and 3 embryos. Seed germination and growth is strongly influenced by the amount of food reserves stored in seeds (Magagula and Ossom 2011 in Hasnah M, 2013). Keywords: Citrus Seed, Polyembrioni, Seed Viability

Aspergillus flavus affects fresh and dry fruit and vegetable products, and its toxic metabolites, namely aflatoxins, cause serious damage in humans. The objective of this research study was to evaluate the effect of commercial natural products as well as edible and nanostructured chitosan coatings on the development of A. flavus and on the production of aflatoxins in vitro and in tomato. Treatments were as follows: chitosan 1%, chitosan coating, chitosan nanostructured coating, Citrocover 1% (citrus seed extract), Resinadher 0.5% (pine resin extract), mancozeb 2%, and water. The variables were as follows: halo inhibition, spore production, and aflatoxins content. In fruit, the following were evaluated: disease incidence, mycelial growth, and aflatoxin production. An ANOVA (Tukey: p < 0.05) was used. In vitro results showed that Citrocover and Resinadher reduced sporulation (0.2 and 0.9 × 105 spores mL−1, respectively), while chitosan inhibited the production of aflatoxins. With Resinadher and Citrocover, tomato fruit had the lowest incidence, mycelial growth, and aflatoxin production with corresponding values of 0%, 0.0 cm2, and 0.95 ppb, respectively, and 7%, 0.2 cm2, and 1.77 ppb, respectively. The use of Citrocover and Resinadher could be a viable alternative to decrease the development of A. flavus in tomato fruit.
