| چکیده | ||
| آزمایش حاضر به منظور بررسی اثر زمان برداشت میوه (بذر) بر جوانه زنی بذر و رشد دانهال گیاه انبه1 به صورت طرح کاملاً تصادفی با پنج تیمار (پنج مرحله برداشت میوه به ترتیب 85، 95، 105، 115 و 125 روز پس از گل دهی کامل) و چهار تکرار در منطقه میناب (استان هرمزگان) در سال 1386 انجام گردید. نتایج نشان دادند که بیشترین درصد جوانه زنی بذر (67/70 درصد) در تیمار مرحله پنج (125 روز پس از گل دهی کامل) وجود داشت، ولی ارتفاع شاخساره، قطر ساقه، تعداد و سطح برگ در دانهال های شش و 12 ماهه در تیمارهای مرحله اول (85 روز پس از گل دهی کامل) بیشتر بود. همچنین وزن خشک شاخساره و شاخص وزن ریشه (وزن خشک ریشه/ طول ریشه) در دانهال های 12 ماهه نیز از بذور برداشت شده مرحله اول بیشتر بود. بنابراین پیشنهاد می گردد برای دستیابی به رشد و قدرت بهتر دانهال ها، از بذرهای انبه در مراحل اولیه رسیدگی میوه (در زمانی که میوه بالغ نشده است) استفاده شود. | ||

| چکیده [English] | ||
| This experiment was conducted to evaluate the effect of fruit (seed) maturity on seed germination and seedling growth in mango (Mangifera indica L.) in Minab (Hormozgan province) in 2007. A completely randomized design with 5 treatments consisted of five stage of fruit harvest (85, 95, 105, 115 and 125 days after anthesis, respectively) and 4 replications was used. The results revealed that the maximum seed germination (70.67%) was found in treatment T5 (125 days after anthesis) at a time when the fruit was matured. But, the shoot length, stem diameter, leaf number and leaf area of 6 or 12 months old seedlings were also found better in treatment T1 and T2 (85 and 95 days after anthesis, respectively). Also, shoot dry weight and root index (root dry weight/ root length) of 12 months old seedlings were also found better in treatment T1 (85 days after anthesis). Therefore, the seeds of mango should be collected before fruit ripening, at a time when the fruit is immature for better seedling growth and vigor index. | ||
