Canna indicaL.roots are used for medicinal purpose. A decoction of the root with fermented rice is used in the treatment of gonorrhea and amenorrhea. The seed of canna is extremely hard, and needs to be "scarified" before sowing. The aim of the present investigation is to determine the hardiness problem of the seed. The seed sample was collected from the IARI, New Delhi in 2008. The wo...

Nitrate reductase (NR) in maize (Zea mays cv W64A x W182E) roots has been stabilized in vitro by the addition of chymostatin to extraction buffer. Contrary to previous observations, levels of NR were higher in the mature root than in root tip sections when chymostatin was included in the extraction buffer. Two forms of NR were identified, an NADH monospecific NR found mainly in the 1cm root tip...

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...

The mustard variety Felicia was used to analyze the response and compensation effects of growth physiology under drought stress rehydration conditions at seedling stage. seedlings were exposed different levels simulated by polyethylene glycol (PEG). parameters, fresh weight, chlorophyll fluorescence, antioxidant system measured. results showed that inhibited roots shoots reduced performance pho...

Seedling abnormalities are a common problem in micropropagation and require investigation. This study aimed to assess the growth characteristics morphoanatomy of stem apices nodal segments basil (Ocimum basilicum) ‘Dark Opal’ inoculated medium containing combinations 6-benzylaminopurine (BAP) naphthaleneacetic acid (NAA). Presence calluses, adventitious roots, abnormal seedlings was quantified ...

Meloidogyne hapla, Pratylenchus penetrans, and Helicotylenchus dihystera, reduced the growth of 'Saranac AR alfalfa seedlings when applied at concentrations of 50 nematodes per plant. All except P. penetrans reduced seedling growth when applied at 25 per seedling. M. hapla reduced growth when applied at 12 per seedling. Nematodes interacted with three pseudomonads to produce greater growth redu...

The spectrum of light significantly influences the growth plants cultivated in closed systems. Five lettuce cultivars with different leaf colours were grown under white (W, 170 ?mol m?2 s?1) and addition red (W + R) or blue B) (230 s?1). until they reached seedling phase (30 days). Each cultivar reacted differently to applied. red-leaved exhibited strongest plasticity response spectrum. stimula...

Wheat (Triticum aestivum L.) seedling establishment is very sensitive to temperature and drought stresses. The present study was conducted investigate the effects of foliar exogenous 5-aminolevulinic acid (5-ALA) application on wheat under different (25, 30, 35 ℃) water regimes (normal 65% watering). Five levels 5-ALA (0, 25, 50, 100 150 mg L-1) were applied as application. Leaf area, stem di...
