Salah satu kendala produsen benih saat ini yaitu penetapan uji vigor dalam pengujian mutu yang lama dan sulit. Vigor merupakan salah fisiologis dapat dijadikan acuan untuk menentukan besarnya benih. metode telah divalidasi ISTA radicle emergence (RE) pada jagung. Penelitian bertujuan waktu pengamatan RE tepat tomat (Solanum lycopersicum L.) mengkorelasikannya dengan tolok ukur fisiologis. dilak...

The methanol extracts of 168 plant species from 68 families were evaluated for their inhibitory activity against lettuce seedling elongation. Among the plant species tested, 12 species had EC50 values for radicle growth inhibition ranging from 0.01 to 5.00 mg fresh weight equivalent mL. Enterolobium contortisiliquum, a traditionally used herbal medicine, exhibited the strongest inhibitory activ...

The purpose of this study was to determine whether acetylation of the sulfonamide drugs in the human body could be prevented by substituting a simple alkyl radicle on the amino group of the drug without otherwise impairing the efficiency of its therapeutic action. Methyl and dimethyl substituted sulfanilamides were made and investigated from a pharmacological and therapeutic viewpoint. Because ...

67 Abstract: The effect of ultraviolet light on the growth and proline contents of four wheat cultivars (Triticum aestivum L., cvs. Bezostoja-1, Doğu-88, Turkey-13, Yayla-305) was investigated. Ultraviolet light inhibited the growth of all of the four wheat cultivars and increased the daily proline contents of both the radicle and coleoptile. Ultraviolet light is a stress factor in the growth o...

This paper presents a unique application of computer vision methods designed to detect germination of lettuce seeds under controlled environment. Two steps involved in this application are image acquisition and image analysis which uses image skeletonization and other image processing algorithms. Seed images are converted to binary images followed by extraction of seed skeletons, which are used...

Seeds of rape (Brassica napus L.) were germinated at various NaCl concentrations up to 200 mM. Germinating levels, seedling growth, triacylglycerol mobilization and lipase activity were investigated. High salt concentrations resulted in retardation of seed germination. Seedling growth as measured by radicle length was severely reduced by NaCl doses higher than 50 mM. Moreover, the mobilization ...
