Abstract

Embryos excised from dry corn (Zea mays L.) kernels were planted several ways to determine the best method of stand establishment. Embryos of 20 sources were (i) planted in peat pots, and seedlings were transplanted to the field while still in the pots; (ii) germinated in petridishes, transferred to peat pots with seedlings later transplanted to the field; (iii) planted directly in the field; (iv) planted directly in the field, surrounded by ground endosperm of other seeds from the same ear; and (v) whole kernels of the same sources were planted in the field as controls. Treatments (i) and (iii) were most successful, each producing about ½ as many mature plants as the control; (ii) and (iv) each produced about 1/5 as many mature plants as the control. Treatment (iii) produced faster, more vigorous growth than (i), while (ii) and (iv) were about equal to each other but considerably behind (i) and (iii) in speed and vigor of growth. All seedlings frcim excised embryos grew less rapidly and less vigorously than those from whole kernels.
