Ammonia Volatilization from Urea-Application Influenced Germination and Early Seedling Growth of Dry Direct-Seeded Rice
Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice. To directly examine soil ammonia volatilization and its damage to seed germination and early seedling growth of dry direct-seeded rice when urea is applied at seeding, two Petri-dish incubation experiments and a field experimen...
متن کاملGermination and Early Seedling Growth of Chaffy-Seeded Grasses at Negative Water Potentials
chaffy-seeded grasses can be debearded, i.e., removal of the hairs and awn (Ahring et al., 1964) or processed to Drought is the most frequent cause of stand establishment failure remove all appendages leaving only caryopses (Beisel, of native grasses. An experiment was conducted to determine the interactions of seed processing and simulated dry conditions on seed 1985). When conditions are favo...
متن کاملEffect of osmopriming on rice seed germination and seedling growth
The experiment was conducted in the Agronomy Laboratory of Agrotechnology Discipline, Khulna University, Khulna from 29th August to 17th September, 2009. The experiment was laid out in a Completely Randomized Design (CRD) with two factors and three replications. The aim of the experiment was to study the efficacy of three osmopriming agents viz ., NaCl, KC1 and CaCb with control on seed germina...
متن کاملRice germination and seedling growth in the absence of oxygen.
BACKGROUND Higher plants are aerobic organisms which suffer from the oxygen deficiency imposed by partial or total submergence. However, some plant species have developed strategies to avoid or withstand severe oxygen shortage and, in some cases, the complete absence of oxygen (tissue anoxia) for considerable periods of time. SCOPE Rice (Oryza sativa) is one of the few plant species that can ...
متن کاملThe effects of seed priming techniques in improving germination and early seedling growth of Aeluropus Macrostachys
The purpose of this study was to examine the evaluating the potential of seed priming techniques in improving germination and early seedling growth of Aeluropus Macrostachys under salinity stress condition. This study was performed at the Islamic Azad University in Baft city which is located in southeast of kerman province (2250 meters above the sea level, 92º 17 N latitude and 56º 36 E longitu...
