✦ Synopsis

In field experiments with Japanese mint using different growth retardants, chlormequat chloride (2-chloroethyltrimethylammonium chloride) increased the oil content significantly and inhibited growth to some extent only, whilst ethephon (2-chloroethyl phosphonic acid) at 0.06% concentration significantly decreased growth but had no significant effect on oil content . Among the two oil components studied, menthone content only was significantly increased by 0 .06% ethephon whereas the other growth retardants were ineffective . Correlation studies indicated a strong negative relationship of leaf/stem ratio with plant height and herb yield while a strong positive relationship was obtained between the latter two characters . The oil content of the plant was negatively correlated with herb yield and plant height but it was related positively with leaf/stem ratio . * CIMAP Communication No . 688 .
