The growth regulator, PIX (mepiquat chloride l,l-dimethyl-piperdinium chloride), when applied to cotton (Gossypium hirsutum L.) and pecan (Carya illinoensis Koch), caused internode shortening. PIX did not elicit an increase in resistance in cotton to the tobacco budworm[Heliothis virescens (Fab.)], or in pecan to pecan scab (Cladosporium caryigenum (Ell. et Lang) Gottwald]. Also, changes in con...

The relationship between a tree's crown radius and diameter at breast height (DBH) has a variety of uses including forest competition studies, tree crown densities, spacing and stoclung relationships, wildlife habitat suitability models, and tree volume estimations. Estimating DBH from mean crown radius (MCR) is of interest to natural resource managers because MCR can be estimated from high res...

As woody oil crop, pecan [Carya illinoinensis (Wangenh.) K. Koch] may be a solution to the shortage of edible in future. In this study, fruit traits, kernel nutrition and fatty acid composition 10 varieties were determined assess potential pecans for exploitation as oil, well further screen that could used resources understand their development prospects cultivation mountainous hills. The study...

Meloidogyne sp. from five pecan (Carya illinoensis) orchards in Texas were distinctive in host range and iszoyme profiles from common species of Meloidogyne but were morphologically congruent with Meloidogyne partityla Kleynhans, a species previously known only in South Africa. In addition to pecan, species of walnut (Juglans hindsii and J. regia) and hickory (C. ovata) also were hosts. No repr...
