SHOOT REGENERATION FROM PROTOPLASTS OF PENNISETUM AMERICANUM L (MIL CEREAL)
A finely dispersed cell suspension was obtained from embryogenic calli of two genotypes of pearl millet (Pennisetum americanum L. Mil cereal). Protoplasts isolated from both cell suspensions divided and produced globular embryoids and calli. On an agar medium, the embryoids were induced to form albino shoots or albino plantlet- like structures
متن کاملواکنش ریشه ارزن مرواریدی (Pennisetum americanum L.) به تنش خشکی و آبیاری مجدد بعد از دوره تنش
به منظور ارزیابی تاثیر تنش خشکی بر آغازش و رشد ریشه‌های ثانویه ارزن مرواریدی و همچنین واکنش آنها به آبیاری مجدد بعد از تنش خشکی، دو آزمایش گلخانه‌ای در سال 88-87 در موسسه تحقیقات علمی و صنعتی استرالیا (CSIRO) در شهر کانبرا استرالیا اجرا شد. هر دو آزمایش به صورت فاکتوریل در قالب طرح پایه کاملاً تصادفی در گلخانه اجرا گردید. عامل اول در هر دو آزمایش، سطوح مختلف رطوبتی و عامل دوم زمان های برداشت پ...
متن کاملDNA and RNA Levels in Bundle Sheath and Mesophyll Cells of Pearl Millett (Pennisetum americanum).
The DNA content of bundle sheath cells and mesophyll protoplasts from the C(4) plant pearl millet (Pennisetum americanum, Tift 23DB) was determined by microspectrophotometry to be 1.8 to 2.3 and 3.2 to 4.0 picograms/nucleus, respectively. Measurement of RNA by ultraviolet spectroscopy indicated that bundle sheath cells contain twice as much RNA as mesophyll cells.
متن کاملthe response of pearl millet root (pennisetum americanum l.) to drought stress and re-watering
to evaluate the effects of drought stress and re-watering on nodal roots initiation and growth, two glasshouse experiments were conducted in commonwealth scientific and industrial research organization (csiro) in australia during 2008-2009. the experimental designs in both experiments were factorial in a randomized complete block design with two factors. first factor was drought stress and seco...
متن کاملReactions of sorghum-sudangrass hybrids and pearl millet to three species of Meloidogyne.
Sorghum-sudangrass hybrids and pearl millet, Pennisetum americanum (L.) Leeke., are grown extensively in the southeastern United States; the former is used for forage, seed, and summer cover crop and the latter, primarily for grazing, forage, and summer cover crop. The extended period during which these crops can be planted makes them especially adapted to a doublecropping system with winter-gr...
