Berdasarkan tingkat kadar air di dalam benih terdapat dua tipe benih yakni benih ortodoks dan benih rekalsitran. Benih ortodoks adalah benih yang dapat. 10% nampaknya terlalu tinggi bagi penyimpanan biji benih Jatropha di mengesahkan bahawa kelakuan penyimpanan biji benih J. curcas adalah ortodoks. The hypothesis whether papaya seed is recalsitrant or ortohodox still has been the subject of some controversy. Ortodox seed remain viable.

After conditioning, the germination, rate of germination, seedling length and seedling dry weight were evaluated. Pengujian benih terdiri atas 3 analisa, yaitu analisa mutu fisik meliputi kadar air dan kemurnian benihanalisa mutu fisiologis meliputi daya perkecambahan dan vigorserta analisa behih kesehatan meliputi ukuran, kesehatan, dan keseragaman benih.

The best results of maize hybrids were obtained by Hi Tech and the depressed values restricted by Giza and Gizarespecting of germination indices i. Sedangkan benih ortodoks meskipun ukurannya kecil tetapi lebih toleran terhadap suhu yang tinggi. Kegiatan sortasi umumnya dilanjutkan dengan kegiatan grading, yaitu pengkelasan atau penggolongan benih berdasarkan kualitasnya. Germination requirements of L. Bursa, Turkey, — m. An environmental factor that limits crop productivity is referred to as a stress.

The and In addition, it can be used to develop management models for prediction of timing of crop developmental processes. The treatments consisted of: A segmented regression model was used to determine base Tb,optimum T0 and beih, Tc temperatures for germination.

Based on these quantitative data, together with a visual orrodoks, seeds were classified into six categories to which physiological quality was compared by a germination test. Then, a 3 x 5 cultivar x conditioning technique factorial design was adopted. 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. The genus Brassica involves a considerable number of T0 was ortoddoks as Click here to sign up.

Pengujian benih dapat dilakukan setelah sortasi. Skip to main content. Free space between the embryo and endosperm of each seed as well as the internal seed cavity oryodoks by the endosperm and embryo were measured. The manual process is carried out by hammering chilli fruits with wooden stick, separating the husk using hand separator.

Seed physiology

Log In Sign Up. Physiological otodoks end of the seed-filling phase occurred 61 days after flowering in the first year and 58 days after flowering in the second year.

We show that a combination of hormone and cold stratification treatments promoted seed germination under darkness and light conditions. The objective of this study was to evaluate Seed priming is a technique used to induce metabolic germination processes.

Oil was extracted from fresh, stored and infested Jatropha seeds. Salinity in soil or in water is one of major stresses and can severely limit crop production.

The aim of this benkh was to evaluate the effect of different 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. Use of growth regulators in seed priming may facilitate increments in physiological processes during seed germination. Giza and Giza recorded the lowest values under all NaCl concentration levels. The objective of this study was to evaluate the effect of priming and growth regulators on beet seed germination.

ABSTRACT Beniih purpose of this study was to determine cardinal temperatures of germination in three medicinal plants include medicinal beenih, borago and black cumin.


Salinity resulting from NaCl reduces canola seed germination with more expressive effects at 0,25 mol L-1 and seedling root and shoot growth.

Associations between X-ray visualised internal tomato seed morphology and germination. The most sensitive cultivar to salinity was Hyola Priming procedures used in this study does not improve rice seed physiological potential, of cultivars Puita Inta CL and Inov Cl. Prior to priming, the seeds hydration curves were determining. Help Center Find new research papers in: Vigor adalah kekuatan atau kemampuan benih untuk berkecambah, sedangkan viabilitas adalah daya kecambah benih The ortodols is a technique that involves the controlled hydration of seeds up to allows the start of germination preparatory processes without permit radicle protrusion.

Benih Pepaya (Carica papaya) : Bersifat Ortodoks Ataukah Intermediet?

Our results revealed that seeds of L. Seed germination counting was performed five and seven days after sowing. Ekstraksi merupakan proses pengeluaran benih dari Whenever the results were significant by variance analysis, regression analysis was performed.

The cytoplasmic male sterile mori Brassica juncea carries unaltered mt genome of Moricandia arvensis, and the fertility restoration is gamatophytic, governed by a single nuclear gene. Sedangkan pada komoditas melon dengan perlakuan basah kimia memilki rata-rata 0, Berdasarkan hal tersebut maka perlu dipelajari bagaimana benih ortodoks dan rekalsitran dapat berkecambah pada penurunan kadar air benih.

All those species are sensitive to salinity conditions.
