ABSTRACT Soybean [ Glycine max (L.) Merr.] seeds accumulate sucrose, raffinose family oligosaccharides (RFO), phytin, and small amounts of galactopinitols fagopyritols during normal seed maturation. RFO phytin are indigestible by non‐ruminant animals contribute to decreased feed efficiency, reduced mineral adsorption, phosphorous pollution in manure. Low raffinose, stachyose, may have imbibitional chilling sensitivity field emergence. The objective was characterize the profiles soluble...

Abstract Sucrose, raffinose and stachyose accumulate in soybean [ Glycine max L. (Merrill)] embryos during seed maturation. To determine the relationship of plant maternal composition on composition, soluble carbohydrates three 1-cm 2 leaf punches at growth stages (R2, R3, R6) coat cup exudates planta were analysed four 30-min intervals plants (R5) with low-raffinose, low-stachyose (LRS) seeds expressing mutant stc1 phenotype; low-phytin (LRSP1, LRSP2) mips or normal raffinose, phytin...

Abstract The leaf roller Salbia lotanalis Druce (Lepidoptera: Crambidae), a potential biological control agent of Miconia calvescens de Candolle (Melastomataceae), was studied in Costa Rica. Larvae were collected from field site near San José and the insect reared laboratory to study its biology behavior. Chaetotaxy morphology final-instar larvae described. Using head capsule width measurements, we determined five larval instars S. lotanalis. easily on M. seedlings life cycle completed 71.3...

Miconia calvescens de Candolle (Melastomataceae) is an invasive tree considered the most serious threat to natural ecosystems of Hawaii and other Pacific islands. The success M. as species greatly owing its shade tolerance shaded habitat it creates, where many native plant that are light-demanding cannot survive. Salbia lotanalis Druce (Lepidoptera: Crambidae), a neotropical leaf roller attacking calvescens, was evaluated for two mechanisms by which reduces area host plant: feeding...
