CALLUS INDUCTION AND MICROPROPAGATION OF PINEAPPLE (Ananus comocus L.)
(Department of Biotechnology, Sher-e-Bangla Agricultural University, 2015-12) AKTER, FATEMA
The present study was undertaken in Biotechnology Laboratory of the Department of Biotechnology, Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka 1207 during the period from January. 2014 to December. 2014 to evaluate the effect of different plant growth regulators on callus induction, shoot proliferation, root formation and to develop micropropagation protocol of pineapple. Crown tip of pineapple fruits were used as explants and inoculated in MS media supplemented with different cone. of Benzyl adenine (BA), Kinetine (KIN). Indolebutyric acid (IBA). Naphthaleneaeetie acid (NAA) alone or in combination with each other. The treatment 3.0 mgIL KIN + 2.5 mg/L NAA showed the highest percentage (800/0) of callus induction. But minimum days (21.20) to callus induction and maximum weight of callus (2.80 gm) was observed with 2.0 mg/L KIN + 1.5 mg/L NAA treatment. The highest 85% shoot induction was obtained with 3.0 mgfL KIN +1.0 mg/L NAA treatment and minimum 7.60 days was recorded with the same treatment. The highest number of shoots (18.40) after 6 weeks of subculture was recorded in 3.0 mg/L KIN + 1.0 mg/L IBA and the longest shoot (9.04 cm) was found with 3.0 mg/L KIN+2.0 mg/L IBA. The treatment 2.0 mg/L IBA+ 1.5 mg/L NAA showed the highest percentage (75%) of root induction, minimum 16 days to root induction and the longest root (7 cm). But the highest number of roots (15.60) per explants was recorded with 3.0 mg/L IBA+ 1.0 mg/L NAA after 6 weeks of subculture to rooting media. Regenerated plantlets showed, 85% survival in growth chamber conditions and 82% in shade house stage of hardening with Sand : Soil : Cow-dung (1:1:1) and 78 % in open atmosphere at direct sunlight.
EFFECT OF SALT INDUSTRIES BYPRODUCT ON GROWTH AND YIELD OF SWEET PEPPER IN SOILLESS CULTURE
(DEPT. OF HORTICULTURE, 2016) AKTER, FATEMA
The experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to determine the effect of salt industries byproduct on growth and yield of sweet pepper. Five concentrations of salt industries byproduct (SIB) are considered as treatments, viz. S strength Rahman and Inden (2012) + 0 mlL Inden (2012) + 0.25 mlL mlL -1 SIB, S 4 -1 SIB, S 3 -1 SIB, S 2 1 = ¾ strength Rahman and = ¾ strength Rahman and Inden (2012) + 0.5 = ¾ strength Rahman and Inden (2012) + 0.75 mlL = ¾ strength Rahman and Inden (2012) + 1.0 mlL -1 SIB. The experiment was conducted in a randomized completely block design with three replications. Different concentration of salt industries by product showed significant variation in most of the parameters. The highest plant height, the maximum number of fruit/plant, individual fruit weight, fruit length, fruit diameter, fruit volume, and yield were found highest in S But all the parameters were drastically reduced when S 5 3. treatment was applied. Therefore, S treatment can be used for sweet pepper cultivation in soilless culture system in Bangladesh.
WEB BASED INTERACTION SYSTEM BETWEEN PRODUCT OWNER AND SHIPPING AGENT
(Daffodil International University, 2018-12-12) SHUVO, K. M. ASADUZZAMAN; TUSHAR, MEHADI HASAN; AKTER, FATEMA
In Bangladesh shipping agents are not as much available as product owner needs. Here, product owner can’t find shipping agent just because they are not in one platform. He needs to go door to door to find one agent for the deal which is liable to raise the product cost. Hence, to develop a project to minimize this problem is a time demand since there is no remarkable platform for making an easy communication between Shipping agent and product owner. The aim of this project is to help shipping agents and product owner to discover better and appropriate arrangements for them through a web based application to make their business bargain effective and cost efficient with the minimum cost. In our website there are lots of shipping agents with whom product owner can make deal according to their range of abilities which will help the destitute individuals by having the item in correct time. In the season of emergency, this site can help shipping agents and product owner to discover better and appropriate arrangements for them also.
