Trunk injection of iron compounds as a treatment for overcoming iron chlorosis in apple trees

Trunk injection of iron compounds as a treatment for overcoming iron chlorosis in apple trees. Barney, Danny L.; Walser, Ronald H.; Davis, Tim D.; Williams, C. Frank (Dep. Agron. Hortic., Brigham Young Univ., Provo, UT 84602, USA). HortScience, 20(2), 236-8 (English) 1985. CODEN: HJHSAR. ISSN: 0018-5345. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Severely chlorotic Red Delicious apple (Malus domestica) trees growing on a calcareous soil were treated for Fe chlorosis with pressure injections of 1.0% (wt./wt.) solns. of FeSO4.7H2O, ferric citrate [3522-50-7], or Fe-Sequestrene-330 (Fe-330) [90093-27-9]. Injections were made in Sept. of 1981 and in Apr., June, and July of 1983. All treatments increased chlorophyll concns. compared to controls, and treatments made in Sept. of 1981 and in Apr. and June of 1983 increased shoot growth during the 1983 growing season compared to controls. Although the treatments did result in a temporary increase in foliar Fe content, there was not a strong correlation between foliar Fe and chlorophyll concn. FeSO4 and Fe-330 were more effective than ferric citric in alleviating chlorosis. Injections made in Apr. and June of 1983 greatly increased bloom in May of 1984, compared to trees injected in July of 1983 and the untreated controls. Hence, injections should be made early in the season (before July) to promote bloom the following growing season.

Retention and distribution of iron added to cow's milk and human milk as various salts and chelates

Retention and distribution of iron added to cow's milk and human milk as various salts and chelates. Kwock, Rhodinne O.; Keen, Carl L.; Hegenauer, Jack; Saltman, Paul; Hurley, Lucille S.; Loennerdal, Bo (Dep. Nutr., Univ. California, Davis, CA 95616, USA). J. Nutr., 114(8), 1454-61 (English) 1984. CODEN: JONUAI. ISSN: 0022-3166. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Section cross-reference(s): 17 Weanling C57BL/6J mice were fed an evapd. cow's milk diet or human milk supplemented with vitamins and minerals (except for Fe). Following an adjustment period, individual groups received a single dose of milk radioactively labeled with Fe(II)Cl2, Fe(II)SO4, Fe(III)NTA [16448-54-7], Fe(III)EDTA [17099-81-9], Fe(III)citrate [3522-50-7], or Fe(III)lactobionate [84240-23-3]. Whole-body retention was measured after 4 days; animals were then killed and individual tissues were counted for radioactivity. Fe from FeCl2, FeSO4, and FeNTA were the best retained from both milk diets. Fe citrate had a significantly lower Fe retention than all other groups in either diet and is probably not an effective chelate for delivering Fe to milk diets. Fe bioavailability was higher from the human milk diets than from the cow's milk diets from all vehicles used except citrate and lactobionate. Absorption of Fe citrate was similar from the 2 milk diets, whereas percent retention from Fe lactobionate was higher from cow's milk than from human milk. Tissue distribution of retained Fe was similar for the milk diets and among the groups, indicating that, once absorbed, Fe from the different vehicles is metabolized in a similar manner.
