【本資訊由中國糧油儀器網提供】 玉米胚乳占玉米整粒的80%以上，如果胚乳出現發育不良的情況，其籽粒的充實度將差，玉米籽粒容重將有一定的降低。玉米容重器cedingyumiziliyuyichuanbiaodazhuyaoshoudaosanbeitipeiruyichuanxiaoyingyingxiang。zhejinyibushuomingleyumipeiruyichuanchayikenengduiyumirongzhongdeyingxiang，jiyumipinzhongduiyumirongzhongdeyingxiang。
使用玉米容重器分析了29個ge山shan東dong省sheng玉yu米mi品pin種zhong容rong重zhong的de差cha異yi，發fa現xian玉yu米mi容rong重zhong受shou到dao基ji因yin型xing的de顯xian著zhu影ying響xiang。受shou基ji因yin型xing控kong製zhi的de粒li型xing是shi決jue定ding容rong重zhong的de重zhong要yao因yin素su，不bu同tong粒li型xing之zhi間jian容rong重zhong差cha異yi顯xian著zhu，爆bao裂lie型xing玉yu米mi容rong重zhong值zhi高gao於yu硬ying粒li型xing，硬ying粒li型xing玉yu米mi容rong重zhong普pu遍bian高gao於yu馬ma齒chi型xing玉yu米mi的de容rong重zhong。這zhe可ke能neng是shi因yin為wei圓yuan形xing爆bao裂lie型xing玉yu米mi在zai容rong量liang筒tong內nei排pai列lie間jian隙xi小xiao於yu扁bian平ping形xing籽zi粒li，且qie圓yuan形xing籽zi粒li種zhong皮pi光guang滑hua，故gu圓yuan形xing籽zi粒li比bi扁bian平ping形xing籽zi粒li容rong重zhong高gao。
玉yu米mi生sheng長chang發fa育yu主zhu要yao是shi胚pei乳ru的de生sheng長chang發fa育yu於yu容rong重zhong有you較jiao大da關guan係xi，所suo以yi胚pei乳ru的de發fa育yu情qing況kuang直zhi接jie關guan係xi到dao玉yu米mi的de產chan量liang。玉yu米mi胚pei乳ru的de發fa育yu可ke以yi概gai括kuo為wei兩liang個ge過guo程cheng，一yi是shi胚pei乳ru細xi胞bao的de分fen裂lie增zeng殖zhi和he生sheng長chang，在zai此ci過guo程cheng中zhong澱dian粉fen粒li在zai胚pei乳ru細xi胞bao中zhong形xing成cheng；第二是澱粉的持續合成和積累，在此過程中胚乳細胞中的澱粉粒將逐漸膨大。
