【 摘 要 】

Solution of guazatine triacetate (1, 1'-iminodi [octamethylene] diguanidium triacetate, an agricultural fungicide ; BEFRAN(R)) was sprayed onto wheat plants at a rate of 0.025 or 0.25% at seedling, pre- and post -anthesis stages. Guazatine promoted seedling growth without root fraction. When guazatine was sprayed at pre anthesis, the weight of a head was elevated by 25-27% mainly by increased number of grains and when sprayed at post-anthesis. it was elevated by 20% only by increased weight of a grain. At seedling and anthesis stages, the apparent photosynthetic rate increased by 8-16% but the transpiration rate was practically unchanged. Consequently water use efficiency increased up to 15% by guazatine.
