Regeneration, a remarkable example of developmental plasticity displayed by both plants and animals, involves successive developmental events driven in response to environmental cues. Despite decades of study on the ability of the plant tissues to regenerate a complete fertile shoot system after inductive cues, the mechanisms by which cells acquire pluripotency and subsequently regenerate compl...

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...

The organic waste treatment process using Black Soldier Larvae ( BSF ) produces liquid biofertilizer LB that contains functional microbes and macro micronutrients potentially can stimulate plant growth. study aimed to determine the effectiveness of from bioconversion by on growth arabica coffee seedlings. experiment used a randomized block design with 7 treatments, which consisted of: no (contr...

Coarse and fine root respiration rates of aspen (Populus tremuloides Michx.) were measured at 5, 15 and 25 degrees C. Coarse roots ranged from 0.65 to 4.45 cm in diameter, whereas fine roots were less than 5 mm in diameter. To discriminate between maintenance and growth respiration, root respiration rates were measured during aboveground growing periods and dormant periods. An additional measur...

Effects of relative shoot height and irradiance on shoot and leaf properties of Quercus serrata Thunb. saplings growing in the understory and in gaps were investigated. Photosynthetic photon flux (PPF) at the location of the shoot relative to that in the open (relative PPF; rPPF) and the height of the shoot base relative to tree height (relative height; rHeight) were measured for all current-ye...

evaluation of essential oil yield, morphological and phenological traits of seven populations of twochamomilespecies )matricaria aurea and m. recutita), were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-2012. data were collected for 12 morphological and phenological traits. analysis of variance showed si...

To improve the fertility of soil, several green manure crops are being cultivated. Dhaincha, is an ideal crop used for improvement soil and it also reclaims problematic soils. screen out Dhaincha genotypes based on seedling biomass, a pot culture experiment was carried at Department Plant Breeding Genetics, Anbil Dharmalingam Agricultural College Research Institute, Tiruchirappalli, with four d...

Seasonal phenology is expressed in the annual rhythms of growth and quiescence, which may range from being sharply defined to weakly quantitative. These rhythms, both vegetative reproductive, are a key aspect plant’s survival strategy. They enable plant survive seasonal stresses take advantage favourable conditions, while making pollination efficient through synchronised flowering. Maturation w...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...
