Cucumber mosaic virus (CMV) genus Cucumovirus was recently detected in yam in Ghana, Togo and Benin bringing to six the total number of countries reporting CMV infection in yam worldwide. Two serotyp...
Hybrid yam variety TDr 89/02665 was compared with a local cultivar Igbakumo in on-farm trials in southwestern Nigeria in 2006 and 2007. The trials were to determine the productivity of the hybrid yam ...
The structural changes of crystalloplastids during calcium oxalate crystal idioblasts growth in Japanese yam tubers were examined by transmission electron microscopy. Idioblasts developed in the corte...
Five gibberellins in the early-13-hydroxylation pathway (GA53, GA44, GA19, GA20 and GA1), and six gibberellins in the non-13-hydroxylation pathway (GA12, GA15, GA24, GA9, GA36 and GA4), were detected ...
The mechanism of gravitropism in yam tubers was investigated using two cultivars of Chinese yam, cv. Nagaimo which elongates to form a long tuber, and cv. Genkotsujirou which elongates in the initial ...
The plastid-amyloplast system involved in starch synthesis and accumulation in the Japanese yam tuber was observed by electron microscopes. According to observation with a scanning electron microscope...
To make a new growing area for Chinese yam(D.opposita Thunb.), producers need a lot of rhizophore for seed. To establish an efficient cultural technique for its seed propagation, we examined the effec...
To establish a cultural technique for commercial production of a new high yielding variety of Chinese yam (D.opposita Thunb.) "Shintanmaru", we examined the effects of seed rhizophore weight and plant...
Present situation and several ways to improve productivity in Chinese yam(Dioscorea opposita Thunb.)cultivation.
To improve productivity in the cultivation of Chinese yam 'Tanba-yamanoimo' (Dioscorea opposita Thunb.), we investigated the effect of virus free plants on the yield of a high yielding variety 'Shinta...
Chinese Yam is produced by vegetative reproduction and the tubers inherit the genetic shape-traits of the seed tubers. Shape is an important factor affecting commercial classification and price, and i...
The chemical composition of essential oils from leaves of Helichrysum cameroonense Hutch. and Dalziel, Helichrysum cymosum Sensu C. D. Adam, Helichrysum globosum Sch. Bip. ex A. Rich. and flowers of H...
为了探索纳米碳酸钙助剂对鲜切山药保鲜效果的影响,研究了壳聚糖添加纳米碳酸钙助剂对鲜切山药在10℃下品质的影响。结果表明,壳聚糖添加纳米碳酸钙助剂处理后鲜切山药的总酸度、Vc含量和L值分别比单独使用壳聚糖高10.5%、8.4%和6.9%;失重率和总酚含量分别比单独使用壳聚糖低9.2%和8.3%。壳聚糖添加纳米碳酸钙助剂可显著抑制多酚氧化酶和过氧化物酶活性,延缓果实褐变,延长货架期。添加纳米碳酸钙助剂...
Yam anthracnose and virus diseases are the most important biotic constraints affecting yam production in the world. Six Dioscorea alata genotypes were evaluated for their reaction to these diseases ...
Yam cultivation in dry season was tested in the farmer’s field at inland valley in Niger state, Nigeria. Water yam (Dioscorea alata) variety TDa 95/00328 had the greater response to the gibbe...
