Biochar impact on development and productivity of pepper and tomato grown in fertigated soilless media
Ellen R. Graber,Yael Meller Harel,Max Kolton,Eddie Cytryn,A. Silber,Dalia Rav David,Ludmilla Tsechansky,Menahem Borenshtein,Yigal Elad +8 more
TL;DR: Two related alternatives are conjecture to explain the improved plant performance under biochar treatment: the biochar stimulated shifts in microbial populations towards beneficial plant growth promoting rhizobacteria or fungi, and low doses of biochar chemicals, many of which are phytotoxic or biocidal at high concentrations, stimulated plant growth at low doses (hormesis).
Journal ArticleDOI
Induction of Systemic Resistance in Plants by Biochar, a Soil-Applied Carbon Sequestering Agent
Yigal Elad,Dalia Rav David,Yael Meller Harel,Menahem Borenshtein,Hananel Ben Kalifa,A. Silber,Ellen R. Graber +6 more
TL;DR: It is found that soil-applied biochar induces systemic resistance to the foliar fungal pathogens Botrytis cinerea and Leveillula taurica on pepper and tomato and to the broad mite pest on pepper.
Journal ArticleDOI
Expression and Functional Analyses of the Plastid Lipid-Associated Protein CHRC Suggest Its Role in Chromoplastogenesis and Stress
Yael Leitner-Dagan,Marianna Ovadis,Elena Shklarman,Yigal Elad,Dalia Rav David,Alexander Vainstein +5 more
TL;DR: The functionality of CHRC is studied, which is activated in vegetative tissues similar to other PAPs by various biotic and abiotic stresses, and the transgenic LeCHRC-suppressed plants were significantly more susceptible to Botrytis cinerea infection, suggesting CHRC's involvement in plant protection under stress conditions and supporting the general, evolutionarily preserved role of P APs.
Journal ArticleDOI
Effect of colored shade nets on pepper powdery mildew (Leveillula taurica).
TL;DR: Growing sweet pepper under shade nets results in increased yields and also in higher powdery mildew severity, which is negatively associated with the rate of shading and is variably affected by the quality of light filtered through the different colored shade nets.
