The impact of cold radiofrequency air plasma on the wetting properties and water imbibition of beans (Phaseolus vulgaris) was studied. The influence of plasma on wetting of a cotyledon and seed coat (testa) was elucidated. It was established that cold plasma treatment leads to hydrophilization of the cotyledon and tissues constituting the testa when they are separately exposed to plasma. By con...
Cover crop use in organic rice cropping systems efficiently manages the two most limiting factors agriculture - weed competition and nutrient availability. Nonetheless, cover biomasses on soil surfaces under anaerobic conditions flooded produce acids (mainly acetic acid) that cause early phytotoxicity to seedling coleoptile roots. This study evaluated dose-response of acid germination rates pos...
Arsenic (As) contamination is an important environmental consequence in some parts of salinity-affected South (S) and South-East (SE) Asia. In this study, we investigated the individual and combined phytotoxicity of arsenic (As) [arsenate; As(V)] and salinity (NaCl) on early seedling growth (ESG) of saline-tolerant and non-tolerant rice varieties. Germination percentage (GP), germination speed ...
The objective of this work was to determine new approaches that could improve the germination quality Burkea africana seeds under reproducible conditions and by means available farmers with a view its propagation. tests concerned influence three pre-germinative treatments. It is about light scarification (Scl), medium (Scm) deep (Scd) in order some parameters are latency time, time germination,...
Extensive and kinetically well-defined water exchanges occur during germination of seeds. A putative role for aquaporins in this process was investigated in Arabidopsis. Macro-arrays carrying aquaporin gene-specific tags and antibodies raised against aquaporin subclasses revealed two distinct aquaporin expression programs between dry seeds and young seedlings. High expression levels of a restri...
In this study, the biocontrol efficacies of 14 endophytic bacterial strains were tested against Blumeria graminis f. sp. tritici (Bgt) in pot experiments under greenhouse conditions. Bacillus subtilis strain E1R-j significantly reduced disease index and exhibited the best control (90.97%). When different formulations of E1R-j were sprayed 24 h before Bgt inoculation, fermentation liquid without...
Salinity is an abiotic stress that reduces the seed germination and productivity of tomatoes. Magnetic treatment has been shown to have a positive effect on germination, seedling growth, various crop species. Therefore, three experiments were conducted evaluate whether treating saline water or seeds with magnetic field can improve tomatoes (Solanum lycopersicum) under salinity stress. To growth...
One of the keys to successful shallot cultivation with True Seed Shallot (TSS) is determined by viability and vigor at nursery. The aim study was determine effect varieties types natural Plant Growth Regulatory (PGR) on germination TSS index. conducted Technology Laboratory Agricultural Development Polytechnic Yogyakarta Magelang in July 2021 using a factorial Completely Randomized Design (CRD)...
The use of chemical pesticides leads to negative impacts such as pesticide residue problem and weed resistance. Thus, an economical and environmentally safe method such as allelopathy needs to be explored for controlling weeds in agricultural areas. Therefore, a study was conducted to determine the allelopathic effects of the aqueous leaf extract and leaf debris (incorporated into the soil) of ...
Understanding the responses of seeds to detriment interaction external factors is one challenges research, especially with little explored species such as Sonchus oleraceus L. Thus, objective was investigate effect cultivation system, storage time and temperature on physiological potential Seeds were used two systems (organic conventional) in three times (0, 90 180 days) submitted at temperatur...
