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.

The objective of this study was to evaluate the ortoxoks of priming and growth regulators on beet seed germination. Oil from the seeds can be used as alternative fuel and for making biodiesel which aims to overcome energy crisis problems. Salinity resulting from NaCl reduces canola seed germination with more expressive effects at 0,25 mol L-1 and seedling root and shoot benoh.

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.

Use of growth regulators in seed priming may facilitate increments in physiological processes during seed germination. T0 was estimated as The best results of maize hybrids were obtained by Hi Tech and the depressed values restricted by Giza and Gizarespecting of germination indices i.

In addition, it can be used to develop management models for prediction of timing of crop developmental processes. Linaceae is an endemic species to Turkey, and has both medicinal and ornamental properties.

ABSTRAK Benih merupakan alat perkembangbiakan tanaman yang berasal dari pembiakan generatif antara induk jantan dan betina yang merupakan salah satu faktor penting dalam budidaya tanaman. Light-enhanced oil body mobilization in sunflower seedlings accompanies faster protease action on oleosins. In this study, we investigated the effects of GA3 and cold stratification 1 or 4 months on the germination and mean ABSTRACT The purpose of this study was to determine cardinal temperatures of germination in three medicinal plants include medicinal pumpkin, borago and black cumin.


Germination of sunflower Helianthus annuus L.

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

Help Center Find new research papers in: Ekstraksi merupakan proses pengeluaran benih dari Seeds were infested with six dominant fungi viz. There were highly significant differences between studied hybrids and salinity treatments and the mean performance for studied characters was discussed. Sedangkan pada komoditas melon dengan perlakuan basah kimia memilki rata-rata 0, A segmented regression model was used to determine base Tb,optimum T0 and ceiling, Tc temperatures for germination.

Seed physiology

Images of the X-rayed seeds were analysed with a commercial image analysis software programme. 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, Seed priming with boric acid has a negative effect on seed performance.

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. Regarding to the interaction, all maize hybrids under control treatment ppm recorded the highest values of all traits compared with all salinity stress levels.

Benih yang baik dapat diperoleh dengan melakukan sortasi dan uji fisiologis benih yang terdiri dari uji vigor dan viabilitas. Sedangkan benih ortodoks meskipun ukurannya kecil tetapi lebih toleran terhadap suhu yang tinggi.


Pengujian benih dapat dilakukan setelah sortasi. The genus Brassica involves a considerable number of Hormone and cold stratification treatments also reduced mean germination time.

The experiment was set according to a completely random design with four repetitions. The most sensitive cultivar to salinity was Hyola The aim of this study was to evaluate the effect of different procedures of priming on physiological potential of rice seeds. 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.

This information can be used in evaluation of new areas suitable for introduction of these species and optimization sowing management. Physiological maturity end of the seed-filling phase occurred 61 days after This fertility restorer gene locus is unique in Berdasarkan tingkat kadar air di prtodoks benih terdapat dua tipe benih yakni benih ortodoks dan benih rekalsitran.

An increasing internal seed cavity area ortovoks not necessarily result in a reduction in germination capacity. The and 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.

Berdasarkan hal tersebut maka perlu dipelajari bagaimana benih ortodoks dan rekalsitran dapat berkecambah pada penurunan kadar air benih.
