| dc.description | Rice (Oryza sativa L.) is the staple cereal food for about half portion of the world's
populace. However, more than 90 % of rice is consumed in Asia, where it is the staple
food for a greater part of the populace, including 560 million hungry people in the area
(Mohanty, 2013). In Asian countries, Rice gives about half of the total dietary
carbohydrate providing 50-80% starch and providing 50-80% of the daily calorie
consumption (Khush, 2005).
Aromatic rice (Oryza sativa L.) is favored by consumer everywhere throughout the
world because of its flavor and palatability. Small grain aromatic (SGA) rice has been
the central elements for preparation of numerous fabulous dishes in Bangladesh and
Eastern India.
The imperative element of this type of rice is its satisfactory aroma which has been
considered as a high value added trait for rice. Grain nature of rice play a vital role in
customers' acceptability and after yield, it is the second significant breeding
consideration (Jewel et al., 2011). | en_US |
| dc.description.abstract | A field experiment was conducted to study the effect of 6-Benzyl aminopurine (6-BAP)
on morpho-physiological, yield and yield characters of three aromatic rice varieties cv.
Chinigura (V1), Kataribhog (V2) and Kalijira (V3). The 6-BAP was sprayed 0, 20, 40, 60
and 80 ppm at vegetative and pre flowering stages. Results showed that the morphophysiological, yield and yield attributes were significantly different among the varieties
studied under the application of different levels of 6-BAP. There was a significant
relationship among the varieties and different levels of 6-BAP on both vegetative and
harvesting stages regarding tillers hill-1
. A statistically significant variaties was observed
in plant length, root depth, panicle length, effective and non-effective tiller, grain yield,
biological yield, harvesting index, chlorophyll-a, total chlorophyll content, and poline
content except straw yield and 1000 grain weight. Among three varieties, Kataribhog had
more yielding ability by using 60 ppm T4 6-BAP than those of chinigura and kalijira.
The highest plant height (172.9 cm) was found in V1 variety using 60 ppm of 6-BAP.
The highest panicle length was in V1 variety using 40 ppm of 6-BAP and the lowest was
found in V2 variety under control treatment. The maximum amount of grain per panicle
(287.00) was found in V2 variety in the treatment T4 (60 ppm) and (241.1) was the
lowest value which was found in V1 variety in the control T1 treatment. The maximum
amount of chlorophyll-a (24.59 mg g-1) found at V1×T4 and the lowest amount of
chlorophyll a (14.87 mg g-1
) showed by the treatment V2 × T2. The highest amount of
total chlorophyll content (25.95 mg g-1
) was in V1×T4 treatments while the lowest
amount (18.35 mg g-1
) was at V3×T5 treatments. The highest proline content (0.35 mg g1
) was recorded in V1×T2 and the lowest proline content (0.26 mg g-1
) was recorded in
V2×T4. Some yield contributing characters of aromatic rice such as grain number per
panicle, grain weight per panicle and total grain yield were influenced due to the
interaction effect of variety and levels of 6-BAP. The spraying with 60 ppm 6-BAP had
the better stimulation on growth on yield of Kataribhog and Kalijira but 80 ppm for
Chinigura. The highest yield was in Kataribhog rice variety (1.66 t ha-1
) spraying 60 ppm
6-BAP twice at vegetative and preflowering stages. Plant growth regulators promote the
growth and yield of aromatic rice varieties which might be an alternative eco-friendly
tool for rice production. Out of the three rice varieties Kataribhog performed better
considering growth and yield parameters. | en_US |
