KUMBHAR B. A. AND DABGAR Y. B. Dept. of Biotechnology, Sheth M.N. Science College, Patan (Gujarat) India R.R. Mehta College of Science and C.L. Parikh College of Commerce, Palanpur (Gujarat) India Abstract This study investigated the allelopathic effects of various weed (Euphorbia thiamifolia L.) plant parts on pigeon pea germination and seedling growth. Aqueous extracts of Euphorbia thiamifoli...

Composted and fresh beef cattle manure samples were extracted with distilled water, acetone, methanol, 2 N sodium hydroxide, 2 N hydrochloric acid, and ether. Bioassay techniques, using the extracts, showed that composted manure extracts had limited effect on seed germination and seeding development of wheat and sorghum. All the extracts of fresh manure, other than distilled water, retarded ger...

this study was conducted to compare different propagation methods and two cultivars (azarshar red, and kashan white) as a rcbd in factorial with four replications in shirvan in 2001. in azarshar red onion, high yield belonged to sets method that 30 percent more than seed sowing. in kashan white bulb cultivar, high yield was get from seedling cultivation and there were no significant differences...

Seed of a Mexican semidwarf wheat (Triticum aestivum L. cv. Inia 66), was obtained from a nitrogen fertilizer field trial grown in Mexico. A high positive correlation was obtained between seed protein content and seedling dry weight after 3 weeks growth (r = +0.92(**)). The seedling dry weight was positively related to the protein content of the aleurone layer and endosperm, but not to the embr...

The effect of plant growth-promoting rhizobacteria (PGPR) on seed germination, seedling growth and yield of field grown maize were evaluated in three experiments. In these experiments six bacterial strains include P.putida strain R-168, P.fluorescens strain R-93, P.fluorescens DSM 50090, P.putida DSM291, A.lipoferum DSM 1691, A.brasilense DSM 1690 were used. Results of first study showed seed I...

In the present study, the effect of different plant growth promoting rhizobacteria (PGPR) like Azospirillum brasilense and Pseudomonas fluorescens on growth parameters and the production of terpenoid indole alkaloids are investigated in two varieties ‘rosea’ and ‘alba’ of Catharanthus roseus. The production of IAA by the PGPR has taken as main criteria in the selection of PGPRs for the seed and...

salinity and drought stress are among the common environmental factors which adversely affect germination and growth of plants. this experiment was conducted to evaluate the effects of salinity and drought stress on turnip seed germination and early growth in seed lab of college of agriculture, university of tehran, during 2010. the experimental design was a complete randomized block with three...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...
