Maize Pollen Availability is a Critical Factor for DH Wheat Development during Extreme Low Temperature | Chapter 10 | Emerging Issues in Science and Technology Vol. 1

With the rapid increase in world population the production of wheat will play a pivotal role on food security and the global economy. Double haploid (DH) technology is a new boon for rapid development of new homozygous lines, which otherwise is achieved in more than seven years through conventional breeding programmes. Limitation of getting maize pollen during low temperature of winter in northern India is a challenge for pseudo-seeds production during wheat maize hybridization for production of DH lines. Pollen of maize is shortly viable and storage of the same at lower temperature and high relative humidity could increase its viability up to a week at 4°C as proposed by earlier studies. Weather conditions greatly influence pollen shedding phenomenon. Cool, humid temperature delays the pollen shed while hot and dry conditions favors the same. The present study was conducted to determine the efficiency of pollen development during extreme cold under four different conditions viz. open condition (under shade from top), in polyhouse, in tunnel (inside polyhouse with hot air supply) and on the ground soil. The plants in tunnel showed early spike emergence and pollen shedding in comparison to plants in natural environment like in open and on the ground. Chlorophyll content was least in plants in tunnel and highest in the plants sowed on the ground. Stem girth and plant height was also less in plants grown under tunnel. Conclusively, for early availability and regular supply of pollen the maize plants should be grown under tunnel with hot air supply.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n
