In this paper, a bionic perception method of navel orange plucking position based on Fmincon and Proportional Differential (PD) angle control is proposed to solve the problems wind disturbance green branches in dynamic unstructured environment. Different from these algorithms that limited two-dimensional images, realizes picking three-dimensional. Meanwhile, robot algorithm are achieved simulta...

abstract navel oranges are cultivated in many countries including iran and in comparable to with other cultivars of citrus have an especial importance in the world the quality and quantity of this product in fluenced by many factors. this research was carried out to investigate the effect of 2,4-d and k2so4 and their interaction on quantitative and qualitative characteristics of sweet orange cv...

In order to ensure edible safety, more regard has been paid to pesticide contamination on agricultural product. Conventional techniques are used to measure pesticide contamination. However, the conventional analyses are not possible because of their destructive characteristic and the limitation of time and labor. Spectral technique can provide a rapid, nondestructive means to assess quality and...

Expanding leaves of Capsicum frutescens L. cv. California Wonder, Cucumis melo L. cv. Hales Best, and Citrus sinensis L. Osbeck cv. Washington Navel showed a marked diurnal periodicity in the incorporation of (14)C from photosynthetically fixed (14)CO(2) into amino acids. Incorporation was virtually nil at the beginning of the photoperiod, reached a maximum in the 6th to 7th hour and decreased ...

A putative citrus vacuolar processing thiolprotease cDNA (Cit-vac) was isolated from a cDNA library of Citrus fruits (Citrus sinensis L. Osbeck var Washington navel). The cDNA is 58 and 57% identical with vacuolar processing seed proteases from castor bean and soybean, respectively. The Citvac sequence shows a typical signal peptide for entering into the endoplasmic reticulum and two glycosylat...
