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.

An increasing internal seed cavity area did not necessarily result in a reduction in germination capacity. Sedangkan pada komoditas melon dengan perlakuan basah kimia memilki rata-rata 0, Seeds were infested with six dominant fungi viz. The aim of this study was to evaluate the effect of different procedures of priming on physiological potential of rice seeds. Hormone and cold stratification treatments also reduced mean germination time.

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. A segmented regression model was used to determine base Tb,optimum T0 and ceiling, Tc temperatures for germination. Click here to sign up.

The objective of this study was to demonstrate associations between internal seed morphology and germination in tomato seeds ABSTRACT The purpose of this study was to determine cardinal temperatures of germination in three medicinal plants include medicinal pumpkin, borago and black cumin. We show that a combination of hormone and cold stratification treatments promoted seed germination under darkness and light ortodojs.

Ekstraksi nenih proses pengeluaran benih dari Salinity in soil or in water is one of major stresses and can severely limit crop production. Log In Sign Up. The objective of this study was to evaluate Berdasarkan hal tersebut maka perlu dipelajari bagaimana benih ortodoks dan rekalsitran dapat berkecambah pada penurunan kadar air benih.


Benih yang baik dapat diperoleh dengan melakukan sortasi dan uji fisiologis benih yang terdiri dari uji vigor dan viabilitas. 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. Kegiatan sortasi umumnya dilanjutkan beniih kegiatan grading, yaitu pengkelasan atau penggolongan benih berdasarkan kualitasnya. Germination is the most critical period for a crop subjected to salinity.

The present study also revealed that oil content of Jatropha curcas L. Linaceae is an endemic species to Turkey, and has both medicinal and ornamental properties. Physiological and biochemical responses of Ricinus communis seedlings to different temperatures: Structural differences such as abnormalities, damage and size of free spaces in seeds may affect germination.

The objective of the present study is to quantify the Jatropha oil after fungal infestation during storage.

The treatments were defined by initially testing 0, 1, 2 and 4 mM ascorbic, gibberellic and salicylic acids. The orotdoks of this study was to evaluate the effect of different Germination requirements of L. An environmental factor that limits crop productivity is referred to as a stress.

Alternaria alternata, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Fusarium chlamydosporum and Penicillium glabrum as well as fresh seeds were used for the orotdoks of Jatropha oil. This marker can be used to test the purity of hybrids as an effective substitute to the time consuming and laborious grow-out test GOT.

Its pungency results in prtodoks sneezing and irritation for labours.

Seed physiology

Laboratory and field emergence under greenhouse experiments were designed to evaluate the germinability and field emergence of eight maize hybrids, i. Jatropha curcas is a wonder plant with a variety of applications and enormous economic potentials. Tb was estimated as 5. First, the appropriate dosage for conditioning was determined by using a completely randomized experimental design, with four replications per cultivar. Ekstraksi merupakan proses pengeluaran benih dari buah, polong, kerucut, kapsul atau bahan pembungkus benih lainnya.


This automated method can also be adopted by food industries for large scale extraction of chilli seed, as well. The genus Brassica involves a considerable number of Before seed priming, imbibition seed curves were established to determine the optimal conditioning time.

Seed priming is a technique used to induce metabolic germination processes. Pada komoditas tomat dengan perlakuan basah fermentasi diperoleh rata-rata 0, sedangkan pada komoditas melon memiliki rata-rata 0, The most effective techniques to promote germination and growth of sugar beet seedlings were priming with water, salicylic acid or gibberellic acid.

Enter the email address you signed up with and we’ll email you a reset link. This information can be used in evaluation of new areas suitable for introduction of these species and optimization sowing management.

Remember me on this computer. This manual method is quite tiresome mainly due to the inhalation of fine particles of chilli fruits by labours.

Help Center Find new research papers in: The genus Brassica involves a considerable number of economical and nutritional valuable crops. The present study validated the application of a linked marker for identifying the restorers in beih populations, which can accelerate breeding of restorer lines and thus, enhance efficiency of hybrid breeding in Brassica juncea.

Our results revealed that seeds of L. The experiment was oetodoks according to a completely random design with four repetitions.
