Effects of combinational treatment with ethephon and gibberellic acid on rice seedling growth and carbohydrate mobilization in seeds under flooded conditions

Plant Production Science, 2018
Early seedling growth, including seedling emergence and vigor, is crucial in direct seeded rice. In this study, we examined the effects of gibberellic acid (GA3) and ethephon (ET) on the early growth of direct seeded rice, and on α-amylase activity and ...

Auxin Relationships of the Rice Coleoptile [PDF]

Plant Physiology, 1954
The work reported here concerns the well known fact that the rice coleoptile elongates more rapidly and more extensively under water than in air. Decapitation experiment carried out with seedlings in air or under water, as well as experiment done with the growth response to the added IAA of floating or submerged coleoptile sections suggest that the ...

Acetic acid disturbs rice germination and post-germination under controlled conditions mimicking green mulching in flooded paddy

Italian Journal of Agronomy, 2022
Cover crop use in organic rice cropping systems efficiently manages the two most limiting factors in organic agriculture - weed competition and nutrient availability.

Identification of genotypes possessing GA responsive reduced height genes in bread wheat (Triticum aestivum)

The Indian Journal of Agricultural Sciences, 2019
The present study was conducted during years 2017-18 and 2018-19 involving 60 wheat genotypes including advance lines and released varieties. Based on the coleoptile length, these were categorised for coleoptile length as short (2.5-4.5 cm), medium (4.6 ...

Morphological Characters Related to Varietal Differences in Tolerance to Deep Sowing in Wheat

Plant Production Science, 2002
In the dry regions, crops are often sown deeper than in the wet regions, because of the relatively high stability of water content of the deep soil layers.

Inheritance of rice cold tolerance at the germination stage

Genetics and Molecular Biology, 2006
Cold tolerance during germination is important for ensuring fast and uniform establishment of a rice crop early in the season. However, evaluation of this trait under field conditions is limited by environmental variation, which makes it difficult to ...

Genomic landscape of the OsTPP7 gene in its haplotype diversity and association with anaerobic germination tolerance in rice

Frontiers in Plant Science, 2023
Early season flooding is a major constraint in direct-seeded rice, as rice genotypes vary in their coleoptile length during anoxia. Trehalose-6-phosphate phosphatase 7 (OsTPP7, Os09g0369400) has been identified as the genetic determinant for anaerobic ...

Field efficacy of a bioherbicide mimic (DiS‐NH2) in a nanoparticle formulation for weed control in durum wheat

Pest Management Science, EarlyView.
A new polymeric nanoparticle formulation containing aminophenoxazinone DiS‐NH2 (2,2′‐disulfanediyldianiline) is proposed as a post‐emergence and contact bioherbicide for weed management in durum wheat. Abstract BACKGROUND Weed‐resistance phenomena have increased dramatically in recent years. Bioherbicides can offer a sustainable alternative to chemical
