【摘要】 分析了黑龙江省主栽的８个玉米杂交种蜡熟后１０ｄ内籽粒在田间自然条件下脱水干燥的速率。结果以东农２４９最快，达１．１１７％／ｄ，合玉１５和四单１９最慢，分别为０．４２３％／ｄ和０．５７０％／ｄ。影响蜡熟后籽粒脱水快慢的既有外部气象原因，也有杂交种本身的原因，如籽粒类型、苞叶长短和松紧等。更多还原

【Abstract】 The natural dry rate of kernel in field after wax ripening in 8 maize hybrids planted in Heilongjiang province was analyzed Hybrid NEAU 249 showed the fastest dry rate l. 117%/d, but Heyu 15 and Sidan 19 were the lowest, 0 423%/d and 0 570%/d respectively The dry rate of kernel was affected by both climatic condition and hydrid nature such as kernel type, husk length etc.更多还原
