Book Description
Root length density (RLD) distributions of budded D24 durian clone grown in different environmental conditions were studied. Root densities declined both horizontally towards the edge of the canopy and vertically with soil depths. Relatively about 34-49% of total RLD were found within the first quarter of the canopy radius while 20-30% were located in the second and third quarter. Only less than 15% of total RLD were found in the last quarter of the canopy radius. Vertically, about 72-87% of RLD were located in the top 45 cm from the soil surface with about 31-42% were on the top first 15 cm. Penetration of roots were small beyond the 75 cm soil depth. This study showed that RLD distribution of budded D24 durian clone were dependent on the environment and results also showed that the pattern did conform to some general pattern of distribution.

Book Description
During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.
