The actual mechanisms involved in this bud abscission remain unclear. This study was conducted to examine the role of nutrients in flower bud abscission and alternate bearing. For this reason, 30-year old [eight lightly cropping (OFF) and eight heavily cropping (ON)] pistachio trees, cv. Owhadi, were selected and used for nutrient measurements. Nutrients [nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg)] were measured in flower buds, leaves, fruits, current shoots, 1-yr-old shoots and roots of both OFF and ON trees at monthly intervals from 10 days after full bloom until harvest. The flower bud abscission percentage was recorded every 15 days, beginning 70 days after full bloom until the end of experiment. Time and fruiting state had a significant effect on the nutrient contents in many organs of alternate bearing pistachio trees. N and P concentrations declined during the period that coincides with that of seed development in most organs, in both OFF and ON trees. N and P concentrations in many organs from ON trees were most times lower than that of OFF ones. In contrast to N and P, in many organs concentrations of K, Ca, and Mg increased throughout the growing season. Ca and Mg concentrations of most organs were greater in ON trees than in OFF trees. There was a significant negative correlation between N and K concentrations in flower bud and leaf, and P concentration in flower bud, leaf, and 1-yr-old shoot with flower bud abscission. It was concluded that nutrients could have an important role in the alternate bearing in pistachio.<br \/>\nAuthor Keywords: alternate bearing; flower bud abscission; mineral content; pistachio<br \/>\nKeyWords Plus: KERMAN PISTACHIO; BUD ABSCISSION; CROP LOAD; VERA-L; LEAVES; FRUIT; MATURE; NITROGEN; GROWTH; YIELD <\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-47655","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Addresses: Baninasab B (reprint author), Isfahan Univ Technol, Coll Agr, Dept Hort, Esfahan 84156, Iran\r\nIsfahan Univ Technol, Coll Agr, Dept Hort, Esfahan 84156, Iran\r\nIsfahan Univ Technol, Coll Agr, Dept Soil Sci, Esfahan 84156, Iran\r\n\r\nE-mail Addresses: bbanin@cc.iut.ac.ir \r\n\r\nPublisher: TAYLOR & FRANCIS INC, 325 CHESTNUT ST, SUITE 800, PHILADELPHIA, PA 19106 USA, http:\/\/www.tandf.co.uk \r\nDiscipline: ENVIRONMENT\/ECOLOGY\r\n\r\nCC Editions\/Collections:  Agriculture, Biology & Environmental Sciences (ABES) \r\n","annee":"2007","mois":"0","numero":"38:1-2","page":"241-258","auteurs":[{"ID":47651,"post_author":"0","post_date":"2018-12-04 04:20:18","post_date_gmt":"2018-12-04 03:20:18","post_content":"","post_title":"Baninasab,","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"baninasab","to_ping":"","pinged":"","post_modified":"2018-12-04 04:20:18","post_modified_gmt":"2018-12-04 03:20:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/baninasab\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47652,"post_author":"0","post_date":"2018-12-04 04:20:18","post_date_gmt":"2018-12-04 03:20:18","post_content":"","post_title":"Rahemi,","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"rahemi","to_ping":"","pinged":"","post_modified":"2018-12-04 04:20:18","post_modified_gmt":"2018-12-04 03:20:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/rahemi\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47653,"post_author":"0","post_date":"2018-12-04 04:20:19","post_date_gmt":"2018-12-04 03:20:19","post_content":"","post_title":"Shariatmadari,","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"shariatmadari","to_ping":"","pinged":"","post_modified":"2018-12-04 04:20:19","post_modified_gmt":"2018-12-04 03:20:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/shariatmadari\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":47654,"post_author":"0","post_date":"2018-12-04 04:20:19","post_date_gmt":"2018-12-04 03:20:19","post_content":"","post_title":"COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"communications-in-soil-science-and-plant-analysis","to_ping":"","pinged":"","post_modified":"2018-12-04 04:20:19","post_modified_gmt":"2018-12-04 03:20:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/communications-in-soil-science-and-plant-analysis\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
