Growth response to temperature of two maize (Zea mays L.) hybrids with differing levels of cold tolerance : a thesis presented in partial fulfillment of the requirements for the degree of Master of Agricultural Science in Plant Science (Seed Technology), Massey University [PDF]

open access: yes, 1993
Low temperatures are a hazard to maize production especially in high altitude and high latitude areas (Eagles, 1979; Hardacre and Eagles, 1986) where it may cause substantial yield reductions through its accumulated effect on vegetative and reprodutive ...

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.

Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Exploring Chemical Variability in the Essential Oil of Artemisia absinthium L. in Relation to Different Phenological Stages and Geographical Location

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The plant essential oils (EOs) play a fundamental role in the adaptation to different habitats and environmental conditions. To verify the influence of these factors on the EO of Artemisia absinthium L., we conducted a pharmacognostic study on this species, collected during both the vegetative (V) and flowering (F) stages, in two different ...

Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Оцінка властивостей особин рослин як основа прогнозування стану популяцій рідкісних та зникаючих видів

open access: yes, 2011
Оцінка властивостей особин рослин є основою досліджень ценопопуляцій і дає можливість прогнозування стану популяцій, що особливо актуально при вивченні рідкісних та зникаючих видів.

Chemodiversity of Essential Oils From Eugenia uniflora L. Collected in Different Phytophysiognomies of the Coastal Region of Rio de Janeiro

open access: yesChemistry &Biodiversity, EarlyView.
Essential oils from Eugenia uniflora collected in different coastal phytophysiognomies of Rio de Janeiro showed notable chemodiversity. GC‐MS and GC‐FID analyses revealed nine chemotypes, mainly rich in curzerene and selina‐1,3,7(11)‐trien‐8‐one. ABSTRACT This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora ...
