Influence of transplanting techniques and age of wash root type seedlings on planting attributes of paddy rice

Cogent Food & Agriculture, 2023
Globally, Rice (Oryza sativa) is one of the most important crops. In India cultivars majorly use wash root type seedlings for rice production. The objective of the study was to assess the influence of transplanting techniques for transplanting wash root ...

Physiological mechanism of exogenous brassinolide alleviating salt stress injury in rice seedlings

Scientific Reports, 2022
Brassinolide (BR) is a sterol compound, which can regulate plant seed germination, flowering, senescence, tropism, photosynthesis, stress resistance, and is closely related to other signaling molecules. This study aimed to evaluate the ability of soaking

Comparative physiological and transcriptomic analyses illuminate common mechanisms by which silicon alleviates cadmium and arsenic toxicity in rice seedlings.

Journal of Environmental Science, 2021
The inessential heavy metal/loids cadmium (Cd) and arsenic (As), which often co-occur in polluted paddy soils, are toxic to rice. Silicon (Si) treatment is known to reduce Cd and As toxicity in rice plants.

Effect of Anoxia on Carbohydrate Metabolism in Rice Seedlings [PDF]

Plant Physiology, 1995
The metabolism of carbohydrates was investigated in rice (Oryza sativa L.) seedlings grown under anoxia. Two phases can be recognized in the utilization of carbohydrates: during the first days of germination under anoxia, the metabolism of sugars is mainly degradative, whereas after the induction of [alpha]-amylase (EC 3.2.1.1) has taken place, the ...

Metabolic Mechanism of Plant Defense against Rice Blast Induced by Probenazole

Metabolites, 2021
The probenazole fungicide is used for controlling rice blast (Magnaporthe grisea) primarily by inducing disease resistance of the plant. To investigate the mechanism of induced plant defense, rice seedlings were treated with probenazole at 15 days post ...

Rice germination and seedling growth in the absence of oxygen [PDF]

Annals of Botany, 2008
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.Rice (Oryza sativa) is one of the few ...

Allometric Characteristics of Rice Seedlings under Different Transplanted Hills and Row Spacing: Impacts on Nitrogen Use Efficiency and Yield

Plants, 2022
The number of seedlings per hill and the configuration of plant row spacing are important management measures to improve rice yield. In the present study, we evaluated the impact of various seedlings per hill (1, 3, 6, and 9 seedlings hill−1) under four ...

Exogenous Gallic Acid Confers Salt Tolerance in Rice Seedlings: Modulation of Ion Homeostasis, Osmoregulation, Antioxidant Defense, and Methylglyoxal Detoxification Systems

Agronomy, 2022
The worldwide saline-affected area is expanding day by day, and soil salinity restricts crop development and productivity, including rice. Considering this, the current study explored the response of gallic acid (GA) in conferring salinity tolerance in ...
