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 ...

Mutagenic effectiveness and efficiency of -rays, EMS, NG and their combinations were studied in grasspea, cv. Dhenkanal Local. NG was 40 times effective than EMS and 1000 times effective than -rays. Combination treatments were exceptionally more effective than single treatments. All the M parameters except 1 seedling root growth showed varied response with doses and mutagens used. Hence, root l...

Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

effect of free and symbiotic nitrogen fixing bacteria on seed and seedling produced seeds under deficit irrigation was conducted in laboratory and field experiments in 2006. in laboratory of karaj’s seed and plant research and certificate institute an experiment was conducted based on factorial in form of completely randomized design with four replications and in field’s of islamic azad univers...

Beta vulgaris belongs to the family Amaranthaceae and was found to have halophytic ancestors. The objective of this study was to investigate the effect of sodium chloride on seed germination, therefore the early stages of seedling growth of Beta vulgaris grown under different salinity levels (0, 100, 150 and 200 mM of NaCl) were studied. The experiment was laid out in a completely randomized de...

In an even-aged pine forest trees can vary considerably in stem size. We examined the basis for this anomaly using a retrospective approach. Twelve open-pollinated families of Pinus densiflora Sieb. et Zucc. were deliberately chosen for their variation in stem volumes at age 32 years. Seedlings obtained from these families were grown to age 6 months under optimal nursery conditions. Endogenous ...

Abstract The research was carried out at the Agricultural Technical College / Mosul, to study effect of cumin extract on barley culture with three factors, first is (comparator and extract), second duration soaking (6 12) hours, third varieties (local, rayhan, zanbaqa), using design (CRD) replicates. At end research, data were recorded analyzed according SAS program, different averages distingu...
