Bottom Line: Seed's germination rate was determined by measuring root and shoot lengths, percent germination, germination index, and inhibition percentage.Biochemical parameters, namely, pigment, carbohydrate, protein, and phenol content, were estimated.Activities of catalase and polyphenol oxidase which are stress marker enzymes were also measured.

ABSTRACT
Triticum vulgare (Wheat) based products are the major dietary source of food in developing countries. In India, it grows in association with boundary plantations of Populus deltoids (poplar). During winter, poplar enters in dormancy which cause a heavy leaf fall at the time of wheat seed germination. Large number of poplar senescence leaves may adversely affect the wheat. Therefore, the present study was performed to examine the effect of senescence poplar leaves on wheat germ and some other biochemical parameters. Seed's germination rate was determined by measuring root and shoot lengths, percent germination, germination index, and inhibition percentage. Biochemical parameters, namely, pigment, carbohydrate, protein, and phenol content, were estimated. Activities of catalase and polyphenol oxidase which are stress marker enzymes were also measured. Results revealed that germination and other biochemical parameters of wheat were severely affected by senescence poplar leaves even at very low concentration. So, intercropping of poplar along with wheat may be chosen carefully as wheat is the major dietary staple.

Effect of PSL extract on sugar contents of wheat. Error bars represents Mean ± S.D of three different experiments. Data were subjected to one-way ANOVA analysis and differences among treatments were determined by Tukey's test. Different letters mean statistical differences at P < 0.05.

Mentions: Total sugar content changed slightly in the presence of PSL extracts (Figure 2). Initially, it increased at 0.001% PSL concentration but decreased thereafter from 0.01 to 10% (5.87% reduction). Result of one-way ANOVA revealed that soluble sugar content of wheat at 0.001 and 0.01% PSL did not significantly differ compared to control. In addition, soluble sugar of wheat in the presence of 0.01% onward was also not significantly differed. Significant difference between treated and untreated wheat supported sensitivity of carbohydrate metabolism to stress and allelochemicals because they interfere with biosynthetic processes [24].
