First Detection Of Naturally Introgressed Bt Cry1ab In Asian Corn Borer [Ostrinia Furnacalis (Guenée)] - Resistant Traditional Maize (Silangan) In The Philippines, Merdelyn T. Caasi-Lit, Eureka Teresa C. Ocampo, Artemio Salazar, Jefferson Paril, Bryan Novio, Bernard Panabang, Angelyn Marta Marmeto

Resistance against insect pests is one of the most promising and highly favored characteristics of an economically important crop. In the Philippines, the Asian corn borer (ACB), Ostrinia furnacalis (Guenée), is the most destructive insect pest of maize. The discovery of Bacillus thuringiensis and the Bt toxin, which led to the development of Bt corn, effectively controlled this pest. In this study, four traditional varieties of maize that showed resistance against ACB were tested for the presence of Bt Cry1Ab protein. Out of these four, a traditional variety from San Carlos City, Pangasinan, which was initially thought to have natural …
Epinasty Accompanies Potassium Nitrate-Induced Flower Bud Break In 'Carabao' Mango [Research Note], Ulysses Besas, Calixto Protacio
Epinasty Accompanies Potassium Nitrate-Induced Flower Bud Break In 'Carabao' Mango [Research Note], Ulysses Besas, Calixto Protacio
The Philippine Agricultural Scientist
The hypothesis that potassium nitrate application promotes epinasty in ‘Carabao’ mango through increased ethylene production was investigated. The degree of drooping, apical primordium growth as affected by shoot ethylene and levels after potassium nitrate spraying were monitored. Evidence presented established for the first time in ‘Carabao’ mango that epinasty occurred just before flower emergence, coinciding with visible bud break, and extended up to 18 days, marking floral anthesis. The possible reasons could be the higher levels of ethylene at 0.31% and earlier increase of ethylene in the shoot apex at four hours and apical primordium growth. Increased ethylene levels at …

The substrate of rice (Oryza sativa) straw employed in this study was procured from local market and stored in polyethene bags until needed. The study was conducted to find out the effects of process optimization of ethanol production from enzymatically saccharified biomass of acid-pretreated rice straw. The results indicated that acid pretreatment has reduced lignin content about 50%. Resultantly, pretreatment raised cellulose contents up to 52% making it suitable for enzymatic saccharification. Optimization of saccharification illustrated that parameters such as biomass, enzyme concentration, temperature, incubation time and agitation indeed affected the action of cellulase on pretreated biomass releasing …
Spectral Lights Based Treatment Enhanced Biomass Accumulation And Secondary Metabolites Production In Callus Culture Of Citrus Reticulata, Faiza Anum, Naveed Iqbal Raja, Tahira Sultana, Abeer Kazmi, Amir Ali, Bushra Qayyum, Anza Afzal, Aneela Nijibat, Zia-Ur-Rehman Mashwani, Abeer Kazmi

Citrus reticulata is a common fruit, belongs to the family Rutaceae. It contains terpenes, phenolics, flavonoids, and vitamin C in conjugation with sugars, amino acids, minerals, organic acids and other biologically important compounds. Application of light elicitation strategies in in vitro plant cultures is acquiring more interest for their potential in feasible biomass accumulation and therapeutically important secondary metabolites production. The present study was designed to investigate the effects of different monochromatic lights (white, red, blue, green, and yellow) on the proliferation and secondary metabolites accumulation in callus cultures of Citrus reticulata raised in response to treatment with AgNPs and …

One of the new strategies to increase the effectiveness of chemical fertilizers, prevent the waste of chemical fertilizers, and increase the yield of agricultural products, is the use of natural compound such as zeolite. This study was conducted to investigate the effects of zeolite (0, 5, 10, and 15 t ha-1) on agronomic and biochemical responses as well as yield components of maize (cv. Simon) under normal (90% field capacity), moderate (75% FC), and severe (60% FC) drought stress conditions during 2017-2019. The results showed that moderate and severe drought stress significantly decreased plant height (10.9% and 19.7%, …
