چکیده
این تحقیق طی سال‌های 1390 و 1391 در موسسه تحقیقات اصلاح و تهیه نهال و بذر کرج با هدف ارزیابی اثر نوع دانه گرده دهنده بر میزان میزان قند، پروتئین، اسید های چرب و اسید های آمینه در بذور حاصل از دورگ گیری بادام A200با شاهرود 12، A230 و تونو در مراحل قبل و بعد از جوانه زنی براساس آزمایش طرح بلوک های تصادفی با 3 تکرار انجام شد.. نتایج نشان داد که در اثر گرده ی رقم "آ230"قبل از جوانه زنی بذر هیبرید "آ200" دارای مقدار قند کل 77 /29میلی گرم بر گرم ماده ی خشک می باشد.این در حالی است که کمترین مقدار قند در اثر گرده ی "تونو" بعد از جوانه زنی بذر بوده است. بیشترین مقدار پروتین دراثر گرده زای"آ230"بوده است و در مقابل کمترین آن از آن "تونو" بعد از جوانه زنی است. میزان متیل اولئات در اثر گرده "آ230" با کمترین مقدار یعنی (74/74%) قبل از جوانه زنی بذر و دراثر گرده رقم "تونو" بیشترین مقدار (79/71%) بعد از جوانه زنی را دارا بود. همچنین بین گرده زاها از نظر اثر گرده بر میزان اسید های آمینه در قبل و بعد از جوانه زنی تفاوت معنی داری مشاهده شد. به طوری که بیشترین مقدار اسید آمینه آسپاراتیک اسید مربوط به رقم "شاهرود 12"قبل از جوانه زنی (570/0%) و کمترین مقدار مربوط به تاثیر گرده رقم "شاهرود 12" بعد از جوانه زنی (136/0%) بود.

چکیده [English]
This study was carried out during 2011 and 2012 on randomized complete bloke design (RCBD) in triplicate with the aim to assess the effect of pollen of A230, Shahrood12 and Tuono on seed germination rate and some of the changes the inner material of seed of A-200 cultivar (mother parent) such as the amino acid, protein, soluble sugar and fatty acids in Steps of before and after germination. The overall results of this study showed that the effect of pollen of A230, Shahrood12 and Tuono on inner material of seeds of A-200 cultivar was significant. The maximum amount of soluble sugars in seed of A-200 from the hybridizing of A230 before germination (29.77%) was observed while the minimum amount of soluble sugars in seed of A-200 from the hybridizing of Shahrood 12 after germination (14.94%) was obtained. Also the maximum amount of total protein in the seeds of A-200 from crossing with of A-230 was observed while the minimum amount of total protein in seed of A-200 from the hybridizing of touno after germination was obtained. Check the resulting of fatty acids levels in seed of A-200 from the hybridizing of A-230, Shahrood 12 and Touno, showed that showed that the effect of pollinizers on fatty acids of seeds of A-200 cultivar was significant. So that, the most and lowest of the fatty acids (methyl oliat) with 74.74% and 71.79% correspond to Touno and A-230respectively. As well as, in this study, it was found that the effect of pollen on the amount of amino acids in seed of A200 from the hybridizing of A-230, Shahrood 12 and Touno, the before and after germination was significant difference. So that, the most and lowest of the Aspartic acid with 0.570% (before germination) and 0.136% (after germination) was correspond to Shahrood 12 and Shahrood 12 respectively.
