In this study, we investigated the effects of GA3 and cold stratification 1 or 4 months on the germination and mean Bursa, Turkey, — m. We show that a combination of hormone and cold stratification treatments promoted seed germination under darkness and light conditions. Hormone and cold stratification treatments also reduced mean germination odtodoks.

Our results revealed that seeds of L. Germination requirements of L. Effect of mycoflora associated during the seed storage on quantity and quality of Jatropha curcas oil. Jatropha curcas is a wonder plant with a variety of applications and enormous economic potentials. Oil from the seeds can be used as alternative fuel and for making biodiesel which aims to overcome energy crisis problems. The objective of the present study is to quantify the Jatropha oil after fungal infestation during storage.

Oil was extracted from fresh, stored and infested Jatropha seeds. Seeds were infested with six dominant fungi viz.

Alternaria alternata, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Fusarium chlamydosporum and Penicillium glabrum as well as fresh seeds were used for the extraction of Jatropha oil.

Fresh seeds produced The present study also revealed that oil content of Jatropha curcas L. An environmental factor that limits crop productivity is referred to as a stress. Salinity in soil or in water is one of major stresses and can severely limit crop production. The genus Brassica involves a considerable number of The genus Brassica involves a considerable number of economical and nutritional valuable crops.

All those species are sensitive to salinity conditions. Germination is the most critical period for a crop subjected to salinity. The objective of this study was to evaluate canola seed germination and seedling growth under conditions of salinity. Canola seeds of the cultivars Hyola 61 and Hyola were submitted to conditions of 0, 0. Seed germination counting was performed five and seven days after sowing. The experiment was set according to a completely random design with four repetitions.

Seed quality factor cultivar means were compared by the Tukey’s test whereas for those of the quantitative factor salinity levels regression equations were adjusted. Salinity resulting from NaCl reduces canola seed germination with more expressive effects at 0,25 mol L-1 and seedling root and shoot growth. The most sensitive cultivar to salinity was Hyola Associations between X-ray visualised internal tomato seed morphology and germination.

Structural differences such as abnormalities, damage and size of free spaces in seeds may affect germination. The objective of this ortidoks was to demonstrate associations between internal seed morphology and germination in tomato seeds The objective of this study was to demonstrate associations between internal seed morphology and germination in tomato seeds.

Samples of seeds from ten lots of each of Santa Clara and Mariana cultivars were evaluated using X-ray visualisation and then subjected to a germination test. Images of the X-rayed seeds were analysed with a commercial image analysis software programme. Free space between the embryo and endosperm of each seed as well as the internal seed cavity occupied by the endosperm and embryo were measured. Based on these quantitative data, together with a visual analysis, seeds were classified into six categories to which physiological quality was compared by a germination test.

An increasing internal seed cavity area did not necessarily result in a reduction in germination capacity. Structural damage affected germination depending on its extent and localisation. The priming is a technique that involves the controlled hydration of seeds up to allows the start of germination preparatory processes without permit radicle protrusion. The aim of this study was to evaluate the effect of different The aim of this study was to evaluate the effect of different procedures of priming on physiological potential of rice seeds.

The treatments consisted of: Prior to priming, the seeds hydration curves were determining. After priming, the seeds evaluated for germination, seedling growth, efficiency of use of the endosperm, germination at lowest temperatures and seedling emergence.

Priming procedures used in this study does not improve rice seed physiological potential, of cultivars Puita Inta CL and Inov Cl. Seed priming with boric acid has a negative effect on seed performance. Seed priming is a technique used to induce metabolic germination processes. Use of growth regulators in seed priming may facilitate increments in physiological processes during seed germination.

The objective of this study was to evaluate The objective of this study was to evaluate the effect of benh and growth regulators on beet seed germination. The treatments were defined by initially testing 0, 1, 2 and 4 mM ascorbic, gibberellic and salicylic acids. Before seed priming, imbibition seed curves were established to determine the optimal conditioning time. After conditioning, the germination, rate of germination, seedling length and seedling dry weight were evaluated.

First, the appropriate dosage for conditioning was determined by using a completely randomized experimental design, with four replications per cultivar. Then, a 3 x 5 cultivar x conditioning technique factorial design was adopted. Whenever the results were significant by variance analysis, regression analysis was performed. Beet orfodoks priming alters irtodoks potential of germination and is influenced by the cultivar and conditioning technique.

The most effective techniques to promote germination and growth of sugar beet venih were priming with water, salicylic acid or gibberellic acid. Berdasarkan tingkat kadar air di dalam benih terdapat dua tipe benih yakni benih ortodoks dan benih rekalsitran. Benih rekalsitran yaitu benih yang tidak dapat disimpan dalam waktu lama, tidak beniy atau mati jika disimpan pada suhu dingin, dan tidak tahan disimpan bila kadar airnya diturunkan sampai di bawah kadar air kritis.

Berdasarkan tabel 1 hasil pengamatan ekstraksi benih pada komoditas tomat dan melon enunjukan bahwa pada komoditas tomat dengan perlakuan basah kimia diperoleh nilai rata-rata 0, Sedangkan pada komoditas melon dengan perlakuan basah kimia memilki rata-rata 0, Pada komoditas tomat dengan perlakuan basah fermentasi diperoleh rata-rata 0, sedangkan pada komoditas melon memiliki rata-rata 0, Laboratory and field emergence under greenhouse experiments were designed to evaluate the germinability and field emergence of eight maize hybrids, i.

The best results of maize hybrids were obtained by Hi Tech and the depressed values restricted by Giza and Gizarespecting of germination indices i. Results also indicated that, all salinity stress levels while compared with control treatment ppm recorded the lowest values of all previous studied traits and the lowest values were obtained by NaCl level ppm. Regarding to the interaction, all maize hybrids under control treatment ppm recorded the highest values of all traits compared with all salinity stress levels.

Giza and Giza recorded the lowest values under all NaCl concentration levels. There were highly significant differences between studied hybrids and salinity treatments and the mean performance for studied characters was discussed. Benih yang baik dapat diperoleh dengan melakukan sortasi dan uji fisiologis benih yang terdiri dari uji vigor dan viabilitas. Vigor adalah kekuatan atau kemampuan benih untuk berkecambah, sedangkan viabilitas adalah daya kecambah benih Vigor adalah kekuatan atau kemampuan benih untuk berkecambah, sedangkan viabilitas adalah daya kecambah benih untuk berkecambah normal di lingkungan yang kurang mendukung.

Sortasi merupakan kegiatan memilah-milah atau menyeleksi benih secara tampak fisik dengan cara memisahkannya dari kotoran, sehingga diperoleh perbedaan benih yang bagus dan tidak bagus. Tujuannya yaitu menjaga dan meningkatkan kemurnian benih. Pengujian benih dapat dilakukan setelah sortasi.

Kegiatan sortasi umumnya dilanjutkan dengan kegiatan grading, yaitu pengkelasan atau penggolongan benih berdasarkan kualitasnya. Pengujian benih terdiri atas 3 analisa, yaitu analisa mutu fisik meliputi kadar air dan kemurnian benihanalisa mutu fisiologis meliputi daya perkecambahan dan vigorserta analisa mutu kesehatan meliputi ukuran, kesehatan, dan keseragaman benih. Till today chilli seeds are separated manually and there is no specific machine designed to separate seed from its pulp.

The manual process is carried out by hammering chilli fruits with wooden stick, separating the husk using hand The manual process is carried out by hammering chilli fruits with wooden stick, separating the husk using hand separator.

Seed physiology

This manual method is quite tiresome mainly due to the inhalation of fine particles of chilli fruits by labours. Its pungency results in continuous sneezing and irritation for labours. Hence, it is necessary to eliminate laborious work and time consumption. The automated process of chilli seed extraction will be the better solution for this problem, which helps farmers. This automated method can also be adopted by food industries for large scale extraction of chilli seed, as well.
