somatic embryogenesis was initiated in c. sativus l. from shoot meristems on ls medium containing bap (2×10-5 m)+naa (2×10-5 m). various stages of somatic embryogenesis were observed in the same medium and the development was asynchronous. somatic embryo development proceeded through well recognized sequences (globular to embryoids) with clearly discernible bipolar regions. matured embryos coul...

The salinization of land is a major factor limiting crop production worldwide. Halophytes adapted to high levels of salinity are likely to possess useful genes for improving crop tolerance to salt stress. In addition, halophytes could provide a food source on marginal lands. However, despite halophytes being salt-tolerant plants, the seeds of several halophytic species will not germinate on sal...

Abrus precatorius is the native plant of India and used in many ways in the Indian Ayurvedic system of medicine. This seeds of the species is dormant due to hard seed coat. So the aim of the study is to remove seed dormancy and enhance germination capacity within a short period. To overcome the problem of dormancy, seeds were scarified by seed scarifier, sand paper, hot water treatment, DMSO an...

Objective: Freshly harvested seeds of “Local” apricot variety were found to be dormant and did not germinate at all. A specific low-temperature stratification treatment was required overcome seed dormancy. The most effective temperature for breaking dormancy, germination, seedling growth 5°C cold (CS). Increased germination percentage recorded when the period prolonged. Seedling developed from ...

In barley, primary dormant grains did not germinate at 30 °C in air and at 15 °C in an atmosphere containing less than 10% O2, while they germinated easily at 15 °C in air. O2 tension in embryos measured with microsensors was 15.8% at 15 °C but only 0.3% at 30 °C. Incubation of grains at 30 °C is known to induce secondary dormancy in barley, and it was shown here that secondary dormancy was als...

A method with high success frequency for propagation of avocado is described. Embryonic axes of mature avocado seeds from six Floridian cultivars were excised and cultured in Murashige and Skoog (MS) medium containing growth regulators. Two types of cytokinins were used: benzyladenine (BA) and thidiazuron (TDZ). Explants were incubated in the dark for 7-10 days to reduce browning, then transfer...
