Effect of plant growth regulators on paddy rice

Abstract

The effect of 4 plant growth regulators (FOR), BAS 111, DCiB, EL 500, Terpal C, on growth and yield of paddy rice was studied in field experiments in Southern China. PGR‐application was practiced by seed soaking, root dipping at transplanting and leaf spraying at elongation stage respectively, using a 2, 5 × 10−5 M concentration of the particular PGR. There was only a minor stem reducing effect of the PGRs at the early stage of tillering, most pronounced after seed soaking. But at harvest time all trials reached the same plant height. In spite of this, seed soaking with EL 500, BAS 111 and Terpal C increased grain yield between 10 and 13 % in the first crop. The results are discussed in connection with a direct PGR‐effect on the generative phase of rice.

Rice straw as a feedstock for biofuels: Availability, recalcitrance, and chemical properties

“…These results demonstrated that maximum rice cultivation area is in India (418.5 lakh hectare) followed by China (298.8 lakh hectare) and Indonesia (128.8 lakh hectare) but maximum rice yield is located in the United States of America followed by China and Japan. Rice plant height also varies from a minimum in China (36.2 cm) to maximum in Thailand (600 cm) …”

“…Rice plant height also varies from a minimum in China (36.2 cm) to maximum in Th ailand (600 cm). 19,[24][25][26][27][28][29] was produced in Asia with India as the second-largest producer aft er China (Table 4). 4 By exporting about 10.8 million tons of rice, India is expected to retain its top position in 2017 followed by Th ailand, Vietnam, Pakistan, and the USA.…”

“…So, growth enhancing facilities lead to the increasing yield and production performance [5]. PGRs (Plant Growth Regulators) stimulate the growth of plant height, tiller number and yield of rice plant [6]. Humic acid enhances cell permeability, which in turn made for more rapid entry of minerals into root cells and so resulted in higher uptake of plant nutrients in rice plant [7].…”
