چکیده

برای بررسی وضعیت گل‌دهی، تشکیل میوه‌چه و میوه در پرتقال تامسون ناول و نارنگی‌های انشوی سوجی‌یاما و میاگاوا در شرایط اقلیمی شرق مازندران، آزمایشی به‌صورت تجزیة مرکب در قالب طرح بلوک‌های کامل تصادفی در سه باغ با مدیریت مختلف و در سه سال متوالی با پنج تکرار به اجرا درآمد. شمار گل، میوه‌چه و میوه ثبت و درصد تشکیل باقی‌مانده تا برداشت میوه‌چه و میوه، نسبت به شمار گل محاسبه شد. در همة رقم‌ها، کمترین شمار گل، میوه‌چه و میوه و در مقابل، بیشترین درصد تشکیل میوه‌چه و میوه، در سال سوم مشاهده شد. باغ 3 کمترین شمار گل، میوه‌چه و میوه و کمترین درصد تشکیل میوه‌چه و میوه را به خود اختصاص داد. به‌طور میانگین، رقم میاگاوا بیشترین شمار میوه‌چه و میوه را داشت. در مقابل، بیشترین درصد تشکیل میوه‌چه و میوه به رقم سوجی‌یاما تعلق داشت. پرتقال تامسون با اینکه از نظر تولید گل رتبة اول را داشت ولی شمار و نیز درصد تشکیل میوه‌چه و میوه در آن، کاهش زیادی نسبت به دو رقم دیگر نشان داد. باتوجه ‌به نتایج، تشکیل گل و میوه در رقم‌های مختلف نسبت به هم روند همسانی داشتند. همچنین عامل‌های محیطی و مدیریتی، تأثیر زیادی بر شمار گل، میوه‌چه و میوه و درصد تشکیل آن‌ها نشان دادند.

چکیده [English]

To investigate flowering, fruitlet and fruit set in Thomson navel orange and Satsuma mandarin cv. Miyagawa and Sugiyama in climatic conditions of eastern Mazandaran, an experiment was performed by combined analysis in randomized complete block design in three different orchards and in three consecutive years with five replications. Number of flowers, fruitlets and fruits were recorded and later fruitlet and fruit set percent were calculated in comparison to flower number. The lowest flower, fruitlet and fruit number and the highest fruitlet and fruit set percent were obtained in the third year. In contrast, orchard 3, had the lowest flower, fruitlet and fruit number as well as fruitlet and fruit set percent. Miyagawa produced maximum fruitlet and fruit number but Sugiyama had the highest fruitlet and fruit set percent. Although, Thompson navel orange had the highest number of flower, but the number and the percentage of fruitlet and fruit set decreased dramatically compared to the two other varieties. In general, it could be concluded that flower and fruit set in different varieties had a similar trends and climatic conditions and management systems might have great effect on them.
