Two experiments were conducted to study the effects of water deficit stress on the germination, emergence and seedling growth of sorghum [Sorghum bicolor (L.) Moench] using Completely Randomised Block Design in four replications. Five sorghum cultivars (Jigurti, Gambella 1107, Meko, 76 T1 #23 and P9403) were evaluated under three water deficit stress treatments (0, -0.20 and -0.85 MPa) using PE...

Allelopathy is a concept that applied in weed management to minimize extensively the reliance on herbicide agriculture. The allelopathic potential of Acalypha wilkesiana, Centrosema pubescens and Phyllanthus amarus Amaranthus cruentus Corchorus olitorius were investigated. Different concentrations leaf aqueous extracts A. C. P. determine their effect under laboratory conditions. profiling phyto...

background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

to study the effects of sowing dates on seed germination and on seed vigor of 12 spring rapeseed cultivars, an experiment was performed in years 2005-2006. during the first year, 12 cultivars of spring rapeseed were planted in the research field of seed and plant improvement institute, karaj, iran. during the second year, standard germination test was conducted to study the performance of the s...

allelopathy refers to the chemical inhibition or stimulation of one species by another which could influence on the growth or germination of other plant and used in control of weed in agricultural practices. in this sense in order to study the possibly allelopathic effects of lemon balm, bitter apple and lemon verbena medicinal plants on control of wild mustard weed, a laboratory experiment was...

abstract most allelopathic studies have demonstrated the importance of live and dead plant tissues as source of allelochemicals. seeds of several species also have inhibitory effects on germination of the same or other species. in order to determine the allelopathic effects of common lambsquarters (chenopodium album) seeds, an experiment was conducted under controlled conditions in birjand univ...

to evaluate the allelopathic effect of essential oil extracted from leaves of eucalyptus globules against some certain weeds and the possibility of that being employed in weed management strategies, laboratory and greenhouse studies were conducted in islamic azad university of khoy in 2007 in the framework of a factorial expreiment based on a randomized complete block design of four replication...

study of magnetic field and seed hydropriming effects on tomato seed germination was done in laboratory of ferdowsi university of mashhad, iran. the experiment was as factorial experiment based on randomized completely design, which was including two level of hydropriming (use of dry seed and soaked seed in distilled water for five hours) and eight level of magnetic field (pretreatment of seeds...
