实验于１９９２年至１９９３年冬季进行，旨在验证一个营救小麦种质资源的简易方法。供试材料经收获后老化处理。自然老化的种胚（生活力为５０％）在琼脂加蔗糖培养基上无菌培养较长时间（４０ｄ）后，大多数能够长出根和芽，但只有芽鞘而没有叶子的苗子即使到了４０ｄ也不发根。经过培养发根的幼苗定植田间后能发育成正常的植株并结出可育的种子。
The experiment took place in the winter of 1992 to 1993, and was designed to validate an easy way to rescue wheat germplasm. Materials tested after the aging treatment. Naturally aged embryos (viability of 50%) After agar-agar supplemented with sucrose medium for a long time (40 days), most of the seedlings that grow roots and shoots, 40d does not hair roots. After cultivating hairy roots of seedlings colonize the field can develop into normal plants and bear fertile seeds.
