AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...

A challenge for Chinese agriculture is to limit the overapplication of nitrogen (N) without reducing grain yield. Roots take up N and participate in N assimilation, facilitating dry matter accumulation in grains. However, little is known about how the root system in soil profile responds to various N supplies. In the present study, N uptake, temporal and spatial distributions of maize roots, an...

the influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘bianca’ and ‘el torro’. third, fourth and fifth nodal explants were cultured on the modified ms medium supplemented with 1.0 and 5.0 mg/l ba. in both the cultivars, higher rate of proliferation (‘bianca’ 3.75; ‘el torro’ 2.65) were obtained from the explants distal to the a...

Orchids are cultivated by tissue culture because their seeds do not have food reserves (endosperm) for growth. All nutrient requirements obtained from media. Propagation causes them to no association with Rhizoctonia mycorrhizae, which needed in growth so that they can interfere orchid both vegetatively and generatively. mycorrhizae a group of sp. form mutual symbiotic orchids. Each has differe...

Biochar is a soil enhancer because it contains macronutrients and has high water-holding capacity. Research on the application of biochar resistance oil palm seedlings to drought stress was conducted determine dosing effect shell watering intervals growth pre-nursery under stress. The research in Sialang Godang Village, Bandar Petalangan District, Pelalawan Riau Province. study April 2021 – Jul...

in vitro multiple shoot regeneration of solanum nigrum l., an indian medicinal plant was accomplished on ms medium utilizing shoot tip and nodal explants. direct multiple shoots differentiated within 6 weeks when explants were cultured on ms medium containing bap (1.0-5.0 mg/l) and kin (1.0-5.0 mg/l) individually. among various concentrations of cytokinins tested, maximum number of multiple sho...

Soil waterlogging reduces gas exchange between the soil and the atmosphere, leading to oxygen deprivation in the rhizosphere. Brachiaria spp. are the most widelysown forage grasses in tropical America. Among commercial Brachiaria grasses, B. humidicola shows superior tolerance to waterlogged soils based on maintenance of growth and reduced leaf chlorophyll loss and senescence. However, little i...

Seedling roots enable plant establishment. Their small phenotypes are measured routinely. Adult root systems are relevant to yield and efficiency, but phenotyping is challenging. Root length exceeds the volume of most pots. Field studies measure partial adult root systems through coring or use seedling roots as adult surrogates. Here, we phenotyped 79 diverse lines of the small grass model Brac...
