摘要:
The present invention relates to a defloration agent for apple trees. The present defloration agent comprises 3-(2-methyl-4-chlorophenoxy)butyric acid (MCPB) or an ester thereof and 2-chloroethylphosphonic acid (ethephon). The present invention provides an excellent defloration effect even when the temperature is low in the blossoming season.

A method of decreasing the physiological fruit drop from fruit trees, which comprises treating at least the overground portion of a growing citrus, peach, apple, pear or persimmon tree with a liquid agricultural composition comprising brassinolide in a concentration of about 1.times.10.sup.-5 ppm to about 5 ppm.
摘要:
A method for improving pigmentation of the rind of anthocyanin-containing apples comprising treating fruit-bearing apple trees or apples before or after harvesting with an effective amount of an agent which comprises 5-aminolevulinic acid, a salt thereof or a mixture thereof as an active component.

In an ADPCM encoding and decoding system comprising an encoder having an adaptive predictor and an adaptive quantizer and a decoder having an adaptive predictor and an inverse adaptive quantizer, the adaptive predictors each comprise: an adaptive-zero predictor of an arbitrary order and an adaptive-pole predictor of an arbitrary order, for input signals with time-varying frequency components; a fixed-pole predictor of an arbitrary order, for input signals the frequency composition of which remains substantially invariant over time; and an offset predictor for rejecting an offset component of the input signals, these elements being connected in series. The adaptive-zero and adaptive-pole predictors generate estimates for voice signals with time-varying frequency components. The fixed-pole predictor generates estimates for voiceband data signals the frequency components of which remain substantially invariant over time. The adaptive predictors effectively operate for voice and voiceband data signals, providing a higher prediction gain. The quantizer provides a stably higher signal-to-quantization noise ratio for modem signals.
摘要:
A method of thinning lateral flowers of apples, comprising applying of flower thinning effective amount of a pyrazole compound represented by general formula (I) ##STR1## wherein R.sub.1 represents an alkyl group having 1 to 4 carbon atoms; andR.sub.2 and R.sub.3, which are the same or different, each represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms,to flowers of apples. A compound in which R.sub.1 and R.sub.2 are each a methyl group, and R.sub.3 is a hydrogen atom is preferred. The pyrazole compounds are applied at a flowering stage of apples, preferably in a period from immediately after full bloom to terminal flowers of apples to 2 days thereafter, typically in a proportion of from about 5 mg to about 75 g per tree at a coverage in a range of from about 20 mg/10a to about 2,000 g/10a.
