(31) The stele includes all primary tissues derived from the procambium consists of pericycle, phloem and xylem.

(32) Both xylem and phloem form a continuous branched system in the whole plant body.

(33) Under the condition of shading in seedling period, the lignified degree of cotton stem declined,(www.Sentencedict.com) cambium and phloem were undeveloped and pint diameter increased.

(34) GA 3 application had the same effect on Hevea brasiliensis phloem as that on Melia azedarach.

(35) The root primordium of Pinus bungeana belongs to induced primordium, which is formed from the cross region of vascular cambium, phloem tissues and pith rays.

(36) Phloem elements and adjacent tissues are the principal feeding sites for most aphids.

(37) The rest of phloem also produced callus through dedifferentiation. In addition, there was callus from xylem.

(38) The aim of this research is to extract and utilize secretion of phloem of Tilia mongolica that use them to increase the zoophobous ability and phylactic power of non-resistant tree species.

(39) Primary vectors for transmitting phytoplasma are insects feeding on the sap of phloem, such as leafhopper, and psylla.

(40) The yellow-green fluorescence appeared in the large phloem parenchymatous cells when the section of life material was observed by fluorescent microscope with blue light.

(41) But boron also exhibits rapid and significant phloem mobility in species for which sorbitol, mannitol, or dulcitol are the primary photosynthates since these polyols can effectively complex boron.

(42) Some segments of hypha, swelled hypha, pelotons and conidiophore were in colonies in cork and secondary phloem.

(43) Cortex (pl. cortices or cortexes) A primary tissue in roots and stems of vascular plants derived from the corpus meristem, that extends inwards from the epidermis to the phloem.
