高溫處理及培養基成分對水稻花藥培養之效果 Taiwan Agricultural Research Institute
葉常青; 蔡新聲; C.C. Yeh; H.S. Tsay.
[[abstract]]水稻花藥培養初期以35±1°C的高溫處理1~2天,再移至25±1°C恆溫培養,可提高癒合組織的誘導率,且不影響其分化率。培養後期的高溫處理則無效。 1 mg/l NAA及4 mg/l kinetin之植物生長素能提高花藥癒合組織之綠苗形成率,但不利於形成後綠苗之生長。 N6無機鹽較MS無機鹽更能抑制花藥癒合組織的褐化,且癒合組織有較旺盛之生長勢。 Rice anthers at uninucleate stage were cultured in medium and incubated at 25°C under darkness for heat trea tment and medium composition studies. It was found that heat treatment of 35°C to the cultured anthers for 1-2 days at the initial culture stage incr eased the percentage of callus inducti on. Nevertheless, no effect was found to the subsequent differentiation of anther-derived callus. There was no beneficial effect either on callus induction or plant regeneration when heat trea tment was given to anthers which have been cultured for 20 days. The plant growth...

高蛋白水稻之育種研究-2.稉稻早晚熟品系間雜交後代之米粒蛋白質含量、抽穗期及其他性狀之遺傳 Taiwan Agricultural Research Institute
郭益全; 謝順景; I.C. Kuo; S.C. Hsieh.
[[abstract]]為探討早熟E基因與米粒蛋白質含量之關係,乃利用攜有不同來源之早熟基因的isogenic系統為材料,進行早晚熟稻間之雜交,以究明各雜交後代集團之米粒蛋白質含量等性狀之遺傳與變異及各性狀彼此間之相關關係等。玆將主要試驗結果摘要如下:早熟親本(BB-11-5-8-6,Bl-1-4-11及BI-14-4-2-6)之米粒蛋白質含量為9.6%,較晚熟親本(40-20-5-6)之7.8%約高1.8%。F2集團蛋白質之平均含量或與低蛋白親本相近或低於兩親之中間值,表示蛋白質含量低者對高者似為顯性或部份顯性。早晚熟稻間雜交組合之F2世代分離成3早熟性:1晚熟性之比例,表示抽穗期受1對主效基因所控制。而由超越分離現象知抽穗期可能尚受微效基因之修飾。F2世代早熟性與蛋白質含量呈負相關,表示早熟植株之米粒蛋白質含量較晚熟者為高。一般而言,各性狀之遺傳相關值遠較環境相關值為大;而表現型相關值則介於兩者之間。米粒蛋白質含量與各性狀間之相關值均為負值,與穗重之負相關則達極顯著之水準,餘者之顯著性概因組合之不同而異。估得米粒蛋白質含量之遺傳率介於0.31~0.56之間,控制米粒蛋白質含量之有效基因對數為1~2對。綜合本試驗結果,推論控制米粒蛋白質含量之因子與早熟E基因之間有連鎖關係,故認為由早晚熟稻閒之雜交集團應可選獲高蛋白質含量之早熟豐產的理想因子型。 Various early maturing isogenic lines of rice having the same genetic background were crossed with the late maturing lines, and protein content, days to heading as well as various...

高蛋白水稻之育種研究-Ⅰ.稉稻早晚熟品系間雜交後代之米粒蛋白質含量及其他農藝性狀之變異 Taiwan Agricultural Research Institute
郭益全; 謝順景; 宋素英; I.C. Kuo; S.C. Hsieh; S.Y. Song.
[[abstract]]利用早晚熟性之isogenic系統的水稻為材料,藉各性狀頻度分布之圖形來描述雜種集團之米粒蛋白質含量及其他農藝性狀之遺傳變異。結果獲知早熟系統為相對短稈、穗短而輕之品系,並觀察到米粒蛋白質含量、株高、穗長及穗重等四性狀與抽穗期之早晚有某種關係存在,而早熟基因團則不影響原遺傳因子型之分蘗能力。文中並曾就各性狀之頻度分布圖形來初步描述各該性狀之族羣特徵。 Genetic variation of protein content and various agronomic traits in the hybrid population of early x late isogenic lines was studied. Variation in protein content and other traits in F2 varied greatly from different cross combinations. From the F2 distribution curve in comparison with that of parental lines, it is assumed that the low protein content is dominant over high protein content. Early maturing is found to be related with high protein content. Further, genetic variations of plant height, panicle number, panicle length, panicle weight, percent seed setting and...

黃麻及鐘麻浸練與調製對纖維品質之關係研究-Ⅰ.黃麻 Taiwan Agricultural Research Institute
凌千里;季景元; C.L. Ling; C.Y. Chi.
[[abstract]](一)浸練,為對黃麻纖維品質最具影響之因子,本研究乃從事(Ⅰ)黃麻鮮皮浸水時不同處理及浸水日數對纖維品質之影響,及(Ⅱ)基部未分離黃麻纖維之處理對於其品質之影響,兩項試驗,以探究改造黃麻浸練技術,期使本省得以生產品質優良之纖維,供省內製袋,並進而拓展外銷,爭取外匯。 (二)鮮皮浸水時不同處理及浸水日數對纖維品質之影響,試驗結果,綜述如下: 1.精洗率與浸練日數有關,浸練6天者,平均精洗率為9.7%,9天者為9.2%,12天為8.7%,16天為81%,即洗練日數愈短,精洗率愈高。 2.精洗麻拉力之高低,與浸練用水關係不大,浸練時覆蓋麻桿,或壓麻距水面深20~30公分,所得纖維,其拉力較不覆蓋者為高,不同之浸練天數為對纖維拉力影響最大之因子,浸練6天者平均拉力負荷為33.66~26.85磅,16天者為15.67~10.46磅,且其差異均呈極顯著標準,故縮短浸練,為提高拉力最有效之方法。 3.結節力、耐摩力、耐屈力等纖維品質,與拉力相仿,浸練用水及覆蓋情形等處理間差異均不大,浸練日數間之差異,則均呈顯著標準,即浸練愈久、結節力、耐摩力、耐屈力愈低。 4.於本省南部夏季,水溫28~32℃,PH值6~7,以生育日數123~140天之原料麻,利用浸水醱酵法浸練黃麻,上覆麻桿,或機械剝皮無麻桿時,壓麻深20~30公分,浸水5~6天,所練得纖維,不但精洗率高,品質亦最佳,如水溫較高,原料麻生育日斐較短,則可視實際纖維分離情形,再縮短浸水天數,以利纖維品質之提高。 (三)基部未分離纖維之處理對於品質之影響,試驗所結果綜述如下: 1.使基部未分離纖維分離之各種處理,以纖維乾後斬除基部未分離部份者最節省時工,惟比之浸練7天後,纖維能自然醱酵分離者,所需之時工多約半倍。...

黃麻扦插採種法之研究 Taiwan Agricultural Research Institute
季景元; 周學淳; 李雨霖; C.Y. Chi; H.S. Chow; Y.L. Li.
[[abstract]]本省農家,過去栽培黃麻,多在麻田一角,或農道旁邊,留少數麻株,採種自給,亦有留整塊麻田,採種出售,惟多去雜不淨,品種既易退化,後作作業,又不方便,土地利用上亦不經濟,且採種期常遭颱風損害,影響採種量,而扦插採種,則可兼顧纖維及種子,慎選插梢,確保品種純良,且育種上交配亦較便利,病蟲害或颱風損害麻株後,扦插仍可採得種子,作者等乃自民國 37 年起,分別在臺北臺灣省農業試驗所及該所臺南棉麻試驗分所,從事抒插採種法之研究,迄 47 年已有相當結果,並經示範推廣,獲有成效,茲應各界需要,將歷年研究結果整理,草擬本報告,將要點摘述如下: (一) 扦插適當時期,約於 8 月上中旬,麻株開花期及幼果期,剪取插梢扦插,蘇活率及採種量最高。 (二) 扦插方法中,目前以麻桿繫插法,蘇活率最高,採種量亦最多,惟較費工,直插法及斜插法最為簡單,在正常之環境下,一般麻農尚可採用 (三) 扦插田最好有流動水,否則扦插後,晨夕宜換水,若插梢置於清水發根後移栽,則易死亡,蘇活率低。種子產量不多,實不適用。 (四) 黃麻扦插在嘉義施用之肥料三要素中,磷肥有增加採種量之效,鉀肥多施,並無增產之效。 (五) 扦插時毋需去葉,花期及乳熟期剪取之插梢,宜用 50 公分者,乳熟期剪取主莖或分枝為插梢者,蘇活率及採種量,無甚差異。 (六) 扦插後經過肥培管理,另生新根,對於養分之吸收力較強,故一般之採種量,較留株採種者為高,以現有推廣品種水上青皮而論,其抨插採種之每公頃平均採種量為 400 至 600 公斤,每株平均可得種子 5 公克,種子採收期約在 11 月底,較留株採種者稍遲。 Jute (Corchorus Capsularis, L) iS one of the most important long vegetable...

凌千里; C.L. Ling.
[[abstract]]本研究以黃麻各品種(系)之植株莖徑,纖維細胞之組織,與其對纖維品質間之相關,舉行試驗期能從基本研究中,提供選育品種,栽培方法之依據,俾本省能以生產品質優良之黃麻纖維。 (一) 纖維細胞束 1黃麻每一纖維細胞束之細胞數,以FS-61-I-2098之26.62±10.22個為最多,臺農選1號之22.50±8.25個為最少,粗莖者顯著多於細莖者。2第一層細胞束中之細胞數均多於第三及第五層尤其中、梢部,第一層比第三及第五層多2-3倍。3纖維細胞束長、濶以TN-7-57為最大,臺農1號為最小,粗莖者多於細莖者。4細胞束羣之層數,粗莖者大於細莖者,基部多於中部,梢部最少,臺農選1號粗莖基部達11~13 層為最多。 (二) 單纖維細胞 1. 單纖維細胞直徑及膜厚,以長果種FS-61-I-2098之17.62±2.86及5.88±1.23μ最大;細胞長度則以TN-7-57之2618±639.31μ為最長,FS-61-I-2098之2196±549.33μ為最短,該品系之長幅比126.60為最小。2. 粗莖之細胞直徑及膜厚平均大於細莖,細胞長度則短於細莖,故粗莖之長幅比較小。3. 植株中部之細胞直徑、膜厚及長度均大於基、梢部,尤其細胞長度差異最為明顯,致中部之細胞長幅比162.64為最大。 (三) 纖維品質 黃麻臺農選1號、TN-7-57,臺農1號等3品種(系)之拉力負荷、耐屈力、長度及色澤等纖維品質差異不大,FS-61-I-2098則較遜。 (四) 纖維細胞組織與纖維品質間之相關 1. 纖維細皰束之澗度與纖維拉力負荷呈顯著負相關r=-0.413. 2. 纖維細胞膜厚與纖維耐屈力呈顯著正相關r=0.587。3. 纖維細胞長度與纖維拉力負荷呈極顯著正相關r=0.563. 4....

龍眼果實脫水試驗 Taiwan Agricultural Research Institute
陳景福; 黃本田; 李彬書; C.F. Chen; P.T. Wong; P. S. Lee.
[[abstract]]龍眼為亞熱帶經濟果樹之一。以臺灣而言,歷年產量皆居全省果產之第四位,果肉鮮美,但不耐久藏,在豐產之年,因產量激增,供過於求,價格下跌,則果農經儕勢將遭受損失,如予以適當之脫水處理,使果品得以不變質不變味而更延長其壽命(Shelf life),以增加果實之商品價值;或使以出口外銷以換取外匯,則於果農經濟至有裨益。 以高雄縣大崗山、大樹鄉及臺南一帶所產之新鮮龍眼為原料,計有鈕子眼、福眼種及晚生種三個品種,利用省農業試驗所鳳山熱帶園藝試驗分所園產加工實驗工廠之小型廂式脫水機(Cabinet dehydrater)及熱室氣流動乾燥法以作脫水試驗。 Longan (Euphoria longana Lam.) is one of the economic fruit trees in the sub-tropical zone. In Taiwan, its yearly production occupied the fourth rank among the annual total fruit yields. The fruit flesh are delicate and palatable, but it cannot be stored for a longer time. During the harvesting season, though its production increa-sed suddenly but low in price, thus it will be influencing the economics of the farmers- in-fruit. For this reason, the preservation of longan by...
