Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Buckwheat - an old crop with new health prospects [PDF]

, 2007
Interest in buckwheat has incresed due to it being a valuable raw material for functional food production. It has been reported to have general beneficial effects on health. Buckwheat competes well with weeds and suffers little from other pests.

Influence of drought stress on the metabolite and ion composition in nectar and nectaries of different day‐ and night‐flowering Nicotiana species

Plant Biology, EarlyView.
Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Transgenerational genetic and epigenetic changes induced by gamma-ray in Fagopyrum species

BMC Plant Biology
Background DNA changes induced by stress may be stable through cell division and passed to subsequent generations. Plant improvement programs require that individuals develop a new heritable trait.

Comparative chloroplast genomics and phylogenetics of Fagopyrum esculentum ssp. ancestrale – A wild ancestor of cultivated buckwheat

BMC Plant Biology, 2008
Background Chloroplast genome sequences are extremely informative about species-interrelationships owing to its non-meiotic and often uniparental inheritance over generations.

Biochemical composition of promising leaves genotypes of buckwheat grown in Himachal Pradesh [PDF]

, 2017
Buckwheat originated from China and being cultivated all over the world, and has become a prominent pseudocereal. Among the pseudocereals (amaranthus, buckwheat and quinoa), buckwheat plant is economically important primarily due to their carbohydrate ...

Effects of Cobalt and Zinc Stress on Rehmannia glutinosa Growth, Bioactive Compounds, Antioxidant Activity, and Molecular Insights

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
This study aimed to investigate the effects of cobalt (Co) and zinc (Zn) on the growth, antioxidant activity, total phenolic and flavonoid contents (TPC and TFC), targeted polyphenolic compounds, and molecular dynamics simulations of Rehmannia glutinosa (R. glutinosa) L.

Improving green manure quality with phosphate rocks in Ontario Canada [PDF]

, 2006
Phosphate rock (PR) was applied to one conventional and two organic dairy fields and planted with buckwheat (Fagopyrum esculentum) as a green manure crop. In total, five types of PR were applied at three application rates in order to determine the yield,

Phenolic compound production by different morphological phenotypes in hairy root cultures of Fagopyrum tataricum Gaertn. [PDF]

, 2011
Hairy roots were obtained after inoculating sterile young stems of Fagopyrum tataricum with Agrobacterium rhizogenes R1000. The established roots displayed two morphological phenotypes when cultured on hormone-free medium containing Murashige-Skoog ...

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops

Journal of Applied Entomology, Volume 150, Issue 2, Page 147-157, March 2026.
ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...
