An effort to find out the smaller size of cuttings for propagation of Morus alba was made in experimental area Department of Forestry, Range Management and Wildlife, University of Agriculture, Faisalabad, Pakistan. Different size of cuttings i.e. 2”, 4”, 6” and 8” were planted in polythene tubes of 3.5”x7”. The effort was also made to compare the performance of cuttings in open air and in polyt...

Roots are the plant parts which facilitate the primary contact between a plant and pollutant and culturing of genetically transformed hairy roots of hyperaccumulator plant sp.Brassica juncea L. grown in vitro was established to study the potential of in vitro hairy root cultures for the uptake and accumulation of heavy metals (Ni and Zn) for their growth and biomass from an aquatic environment....

Z. Naturforsch. 4 8c , 2 8 8 -2 9 3 (1993); received November 3, 1992 Sethoxydim, Growth Inhibition, Cell Cycle, Fatty Acids The mechanism of selective herbicidal action of sethoxydim was investigated by using cul­ tured root tips of corn and pea. Sethoxydim inhibited the growth of susceptible corn root at concentrations of 3 nM and above, but did not affect that of pea at 0.1 m M . Meristemati...

the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...

To study the effects of soil phosphorus (P) application on growth and water relations and nutrient concentration of pistachio seedlings (Badami-e-Zarand) under water stress, a greenhouse experiment was conducted. Treatments were arranged in a factorial manner as a completely randomized design with three replications. Treatments consisted of six P levels (0, 30, 60, 90, 120 and 150 mg P Kg-1 soi...

the effects of above and below-ground competition between chenopodium album and sugar beet (beta vulgaris) on growth, yield and quality of two sugar beet cultivars of morphologically contrasting growth habit have been investigated a factorial experiment (2 × 4) under glass-house conditions in a randomised complete block design with three replications was done. c. album and two sugar beet cultiv...

Abstract Effects of water stress on root and leaf growth rates and their relationships with yield under normal and water stress conditions were examined at the Greenhouse and Research Field of Faculty of Agriculture, Kerman University, Iran, using seven maize cultivars including SC-404, SC-704, BC-666, TC-647, DC-370, Jeta and Kordona. During a period of 14 days, water stress at -0.4 MPa was ...

Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...
