<p>ABSTRACT</p><p>Identification of fruit and seed characters when they reach physiological maturity is very important to get high qualiy chili seed. The purpose of the research was to study the fruit characters and to determine seed physiologycal maturity of six chili genotipes (Capsicum annuum L.) i.e. Anies 1, Anies 2, Seloka 1, Seloka 2, Seloka 3 and SSP. Characterization was assayed at 32, 35, 38, 41, 44 DAA. Chili seed was taken from two groups of branches, lower branches (2nd-5th branches) and upper branches (6-7th branches). The result revealed that seed physiological maturity was achieved at 38-44 DAA, that was indicated by changes of the fruit color from brown to red (Anies 1) and dark green to red on five others genotipe; maximum seed dry weight, seed viability and vigor. When the seed reached physiological maturity, SSP’s had the longest fruit but fruit diameter and weight, seed number and seed weight per fruit was the lowest. However, SSP seed rendement was the highest. Flowers of lower branches developed faster, their fruits size, seed dry weight, and seed number was significantly higher than the upper branches. Nevertheles the seed viability and vigor was not different between lower and upper branches.</p><p>Keywords: fruit color, seed dry weight, seed viability, seed vigor</p>

Pepper (Capsicum annuum L.) seeds of the cultivars Tatashe and Rodo, extracted from fruits sequentially harvested at different maturation stages, were tested for germinability (when freshly harvested) and longevity (over a period of about 17 weeks). Seed dry weight increased with fruit maturation and was maximum when the fruits turned red-ripe. Over-ripening of the fruits for 10 days on the mother plant did not result in a significant seed weight increase, signifying that the seeds were already fully filled when the fruits turned red-ripe. The seeds of the two cultivars started germinating as from 28 days after anthesis (DAA) and peaked at 71.5% and 40% for Tatashe and Rodo respectively, at 44 DAA. The viability of the seeds of Tatashe declined as storage progressed and the more mature the seeds were, the longer they survived. In Rodo, seed viability increased till the end of the storage period due to dormancy, which became progressively broken with age; seeds from more mature fruits survived better. In a second experiment, when fruits of Tatashe were harvested at the colour breaking, red-ripe and over-ripe stages, seed viability and longevity were best from over-ripe fruits.

Sweet pepper (Capsicum annuum L.) is one of the most important vegetable crops in the world because of the nutritional value of its fruits and its economic importance. Calcium (Ca) improves the quality of sweet pepper fruits, and the application of calcite nanoparticles in agricultural practice has a positive effect on the morphological, physiological, and physicochemical properties of the whole plant. The objectives of this study were to investigate the effect of commercial calcite nanoparticles on yield, chemical, physical, morphological, and multispectral properties of sweet pepper fruits using a combination of conventional and novel image-based nondestructive methods of fruit quality analysis. In the field trial, two sweet pepper cultivars, i.e., Šorokšari and Kurtovska kapija, were treated with commercial calcite nanoparticles (at a concentration of 3% and 5%, calcite-based foliar fertilizer (positive control), and water (negative control) three times during vegetation). Sweet pepper fruits were harvested at the time of technological and physiological maturity. Significant differences were observed between pepper cultivars as well as between harvests times. In general, application of calcite nanoparticles reduced yield and increased fruit firmness. However, different effects of calcite nanoparticles were observed on almost all properties depending on the cultivar. In Šorokšari, calcite nanoparticles and calcite-based foliar fertilizers significantly increased N, P, K, Mg, Fe, Zn, Mn, and Cu at technological maturity, as well as P, Ca, Mg, Fe, Zn, Mn, Cu, and N at physiological maturity. However, in Kurtovska kapija, the treatments increased only Ca at technological maturity and only P at physiological maturity. The effect of treatments on fruit morphological properties was observed only at the second harvest. In Šorokšari, calcite nanoparticles (3% and 5%) increased the fruit length, minimal circle area, and minimal circle radius, and it decreased the fruit width and convex hull compared to the positive and negative controls, respectively. In Kurtovska kapija, calcite nanoparticles increased the fruit width and convex hull compared to the controls. At physiological maturity, lower anthocyanin and chlorophyll indices were found in Kurtovska kapija in both treatments with calcite nanoparticles, while in Šorokšari, the opposite effects were observed.

Chilli (Capsicum annuum L.) crop is highly susceptible for the root knot nematode Meloidogyne incognita and every year this nematode causes great loss to the crop. The present study investigated the cumulative effect of two biocontrol agents viz. Pasteuria penetrans and Paecilomyces lilacinus against M. incognita. Two doses of P. penetrans i.e. 50g/Kg and 100g/Kg infested soil were applied either alone or in combination with two doses of P. lilacinus i.e. 4g spore culture/Kg and 6g spore culture/Kg of soil. Application of P. penetrans with P. lilacinus resulted into relatively better improvement in various growth attributes of chilli when compared with the individual application. Amongst the various treatments tested combined application with the higher dose of both bioagents (i.e. 100g P. penetrans infested soil with 6g of P. lilacinus/Kg) showed maximum improvement in fresh and dry weight of shoot and root over the nematode check and it was almost at par with that of the absolute check. The combined application of both the bioagents at higher dose resulted in 139 and 84% increase in dry weight of shoot and root over the nematode check respectively. The combined application of both the bioagents was also observed to cause higher reduction in gall number and nematode population than their individual application except for the treatment having lower dose of the P. penetrans with P. lilacinus where reduction in both the parameters was observed to be at par with that of the either dose of P. penetrans or higher dose of P. lilacinus. Combined application with higher dose of P. penetrans and P. lilacinus showed maximum reduction of 62.6 and 82.2% in gall numbers and nematode population over the nematode check.

Sorghum is a type of carbohydrate-producing serelia plant. Sorghum has a great potential to be developed in Indonesia.  Seed storing time is the time period of the seed storage before the seed is planted again, while the storage of the seed is carried out with the aim of maintaining seed viability in the save period for as long as possible and can be used for the next planting period.  The purpose of this study was to determine the effect of storage time on seed vigor and sprouts of Kawali and P/F-10-90A genotypes. This research was conducted at the Laboratory of Seed and Plant Breeding, Faculty of Agriculture, University of Lampung, Bandar Lampung which runs from February 2017 until February 2018. This study uses split plot design with 3 group replications. The main plot is the storage time (LS) that was consisted of 0, 4, 8 and 12 months storage time period. Subplot is genotype (G), which consists of Kawali (G1 ) and P / F-10-90A (G2). The results showed that seed vigor and sprouts decreased significantly at 4 and 8 months storage time with the percentage of dead seeds 16.7% and 40.7%, while the percentage of normal strong sprouts at 4 months amounted to 74% for genotype P/ F-10-90A  and 8 months 54% for genotype Kawali.  P/F-10 -90A genotypes have higher seed vigor and sprouts vigor compared to Kawali genotypes as indicated by dead seed variables, strong normal sprouts, normal sprout length canopy, long root primary roots, normal sprouts, dry weight normal sprouts, and normally strong sprouts. The effect of interaction  between storage time and genotype was shown by seed vigor of genotype P/F-10-90-A seedlings which were proven to be superior for 4, 8 and 12-month storage time period.  Excellence of genotype P/F-10-90-A make it can be stored and was allowed to be used as good seed on next season farming.

The growth response of 2 vegetable crops to 5 rates of applied phosphorus (P)in the presence or absence of an existing network of extraradical mycorrhizalmycelium was determined in 2 greenhouse pot experiments (Expt 1, autumnwinter; Expt 2, summer autumn) using a low-P growth medium (6 or 5 mgNaHCO3-extractable P/kg for Expt 1 or 2,respectively). In both experiments, capsicum(Capsicum annuum L.) and tomato(Lycopersicon esculentum Mill.) plants were grown at 0(P1 ), 9.2 (P2), 27.5(P3 ), 82.5 (P4 ), or 248(P5) mg P/kg oven-dry soil (spot-placed at sowing)within a nylon mesh (pore size 44 µm). The mesh excluded roots from theoriginal sunflower (Helianthus annuus L.) host plants,to which either live (VAM+) or killed (VAM–) mycorrhizal[Glomus etunicatum Becker & Gerdemann andGlomus mosseae (Nicol. & Gerd.) Gerdemann & Trappe] inoculum was added at sowing. The mesh did allow fungal hyphae togrow into the growth medium contained by the mesh.Whereas VAM+ plants generally had higher P concentrations in indextissues than VAM– plants at low P rates, a concomitant increase in drymatter yield was restricted to the P1 rate. AtP1 in Expt 2, the increase in the dry weight of wholeplants as a result of VAM colonisation was as large as 91.7-fold and 17.9-foldfor capsicum and tomato, respectively. Root starch analysis indicated that thelower dry matter yields of VAM+ plants than of VAM– plants at≥P2 could be attributed to insufficient photosynthateproduction by VAM+ plants to meet the carbon (C) demand of both host andendophytes within the relatively low-light environment of the greenhouse(average daily solar irradiance of 8.4 MJ/m2 forExpt 1 and 13.4 MJ/m2 for Expt 2).The growth response of vegetable crops grown within the greenhouse fromcolonisation by an established mycorrhizal mycelium appears to depend on acritical balance of P and C supply; i.e. at P1, P wasmore limiting than C, and the increased uptake of P as a result ofcolonisation of plant roots by VAM resulted in a growth response. At higher Prates, C was more limiting than P due to low light in the greenhouse, and theadditional demand for photosynthate imposed by the endophytes on the hostresulted in a growth depression relative to non-mycorrhizal plants.
