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.

Medicinal pumpkin Cucurbita pepo subsp. The treatments consisted of: Priming procedures used in this study does not improve rice seed physiological potential, of cultivars Puita Inta CL and Inov Cl.

Till today chilli seeds are separated manually and there is no specific machine designed to separate seed from its pulp. 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.

Seed physiology Research Papers –

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, The genus Brassica involves brnih considerable number of economical and nutritional valuable crops. 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.

Benih rekalsitran yaitu benih yang tidak dapat disimpan dalam waktu lama, tidak tahan atau mati jika disimpan pada suhu dingin, dan tidak tahan disimpan bila kadar airnya diturunkan sampai di bawah kadar air kritis. Salinity resulting from NaCl reduces canola seed germination with more expressive effects at 0,25 mol L-1 and seedling root and shoot growth. Hence, it is necessary to eliminate laborious work and time consumption.


Seed physiology

There were highly significant differences between studied hybrids and salinity treatments and the mean performance for studied characters was discussed. The manual process is carried out by hammering chilli fruits with wooden stick, separating the husk using hand Oleosin mobilization is slower in the dark and all three. Fresh seeds produced The best results of maize hybrids were obtained by Hi Tech and the depressed values restricted by Giza and Gizarespecting of germination indices i.

Structural differences such as abnormalities, damage and size of free spaces in seeds may affect germination. The aim of this study was to evaluate the effect of different The objective of this study was to evaluate This information can be used in evaluation of new areas suitable for introduction of these species and optimization sowing management. The objective of this study was to demonstrate associations between internal seed morphology and germination in tomato seeds Giza and Giza recorded the lowest values under all NaCl concentration levels.

Germination requirements of L. Prior to priming, the seeds hydration curves were determining. ABSTRACT The purpose of this study was to determine cardinal temperatures of germination in three medicinal plants include medicinal pumpkin, borago and black cumin. Seed germination counting was performed five and seven days after sowing.

Beet seed priming alters the potential of germination and is influenced by the cultivar and conditioning technique. Pengujian benih dapat dilakukan setelah sortasi. The treatments were defined by initially testing 0, 1, 2 and 4 mM ascorbic, gibberellic and salicylic acids.

A segmented regression model was used to determine base Tb,optimum T0 and ceiling, Tc temperatures for germination. Vigor adalah kekuatan atau kemampuan benih untuk berkecambah, sedangkan viabilitas adalah daya kecambah benih untuk berkecambah normal di lingkungan yang kurang ortoddoks.

T0 was estimated as Oil was extracted from fresh, stored and infested Jatropha seeds. Hormone and cold stratification treatments also reduced mean germination time.

Seed priming is a technique used to induce metabolic germination processes. Otodoks merupakan kegiatan memilah-milah atau menyeleksi benih secara tampak fisik dengan cara memisahkannya dari kotoran, sehingga diperoleh perbedaan benih yang bagus dan tidak bagus.

Our results revealed that seeds of L. Bursa, Turkey, — m.
